The TurboJPEG API now supports 4:4:1 (transposed 4:1:1) chrominance +subsampling, which allows losslessly transposed or rotated 4:1:1 JPEG images to +be losslessly cropped, partially decompressed, or decompressed to planar YUV +images. + +2. Fixed various segfaults and buffer overruns (CVE-2023-2804) that occurred +when attempting to decompress various specially-crafted malformed +12-bit-per-component and 16-bit-per-component lossless JPEG images using color +quantization or merged chroma upsampling/color conversion. The underlying +cause of these issues was that the color quantization and merged chroma +upsampling/color conversion algorithms were not designed with lossless +decompression in mind. Since libjpeg-turbo explicitly does not support color +conversion when compressing or decompressing lossless JPEG images, merged +chroma upsampling/color conversion never should have been enabled for such +images. Color quantization is a legacy feature that serves little or no +purpose with lossless JPEG images, so it is also now disabled when +decompressing such images. (As a result, djpeg can no longer decompress a +lossless JPEG image into a GIF image.) + +3. Fixed an oversight in 1.4 beta1[8] that caused various segfaults and buffer +overruns when attempting to decompress various specially-crafted malformed +12-bit-per-component JPEG images using djpeg with both color quantization and +RGB565 color conversion enabled. + +4. Fixed an issue whereby `jpeg_crop_scanline()` sometimes miscalculated the +downsampled width for components with 4x2 or 2x4 subsampling factors if +decompression scaling was enabled. This caused the components to be upsampled +incompletely, which caused the color converter to read from uninitialized +memory. With 12-bit data precision, this caused a buffer overrun or underrun +and subsequent segfault if the sample value read from uninitialized memory was +outside of the valid sample range. + +5. Fixed a long-standing issue whereby the `tj3Transform()` function, when used +with the `TJXOP_TRANSPOSE`, `TJXOP_TRANSVERSE`, `TJXOP_ROT90`, or +`TJXOP_ROT270` transform operation and without automatic JPEG destination +buffer (re)allocation or lossless cropping, computed the worst-case transformed +JPEG image size based on the source image dimensions rather than the +transformed image dimensions. If a calling program allocated the JPEG +destination buffer based on the transformed image dimensions, as the API +documentation instructs, and attempted to transform a specially-crafted 4:2:2, +4:4:0, 4:1:1, or 4:4:1 JPEG source image containing a large amount of metadata, +the issue caused `tj3Transform()` to overflow the JPEG destination buffer +rather than fail gracefully. The issue could be worked around by setting +`TJXOPT_COPYNONE`. Note that, irrespective of this issue, `tj3Transform()` +cannot reliably transform JPEG source images that contain a large amount of +metadata unless automatic JPEG destination buffer (re)allocation is used or +`TJXOPT_COPYNONE` is set. + +6. Fixed a regression introduced by 3.0 beta2[6] that prevented the djpeg +`-map` option from working when decompressing 12-bit-per-component lossy JPEG +images. + +7. Fixed an issue that caused the C Huffman encoder (which is not used by +default on x86 and Arm CPUs) to read from uninitialized memory when attempting +to transform a specially-crafted malformed arithmetic-coded JPEG source image +into a baseline Huffman-coded JPEG destination image. + + +2.1.91 (3.0 beta2) +================== + +### Significant changes relative to 2.1.5.1: + +1. Significantly sped up the computation of optimal Huffman tables. This +speeds up the compression of tiny images by as much as 2x and provides a +noticeable speedup for images as large as 256x256 when using optimal Huffman +tables. + +2. All deprecated fields, constructors, and methods in the TurboJPEG Java API +have been removed. + +3. Arithmetic entropy coding is now supported with 12-bit-per-component JPEG +images. + +4. Overhauled the TurboJPEG API to address long-standing limitations and to +make the API more extensible and intuitive: + + - All C function names are now prefixed with `tj3`, and all version +suffixes have been removed from the function names. Future API overhauls will +increment the prefix to `tj4`, etc., thus retaining backward API/ABI +compatibility without versioning each individual function. + - Stateless boolean flags have been replaced with stateful integer API +parameters, the values of which persist between function calls. New +functions/methods (`tj3Set()`/`TJCompressor.set()`/`TJDecompressor.set()` and +`tj3Get()`/`TJCompressor.get()`/`TJDecompressor.get()`) can be used to set and +query the value of a particular API parameter. + - The JPEG quality and subsampling are now implemented using API +parameters rather than stateless function arguments (C) or dedicated set/get +methods (Java.) + - `tj3DecompressHeader()` now stores all relevant information about the +JPEG image, including the width, height, subsampling type, entropy coding +algorithm, etc., in API parameters rather than returning that information +through pointer arguments. + - `TJFLAG_LIMITSCANS`/`TJ.FLAG_LIMITSCANS` has been reimplemented as an +API parameter (`TJPARAM_SCANLIMIT`/`TJ.PARAM_SCANLIMIT`) that allows the number +of scans to be specified. + - Optimized baseline entropy coding (the computation of optimal Huffman +tables, as opposed to using the default Huffman tables) can now be specified, +using a new API parameter (`TJPARAM_OPTIMIZE`/`TJ.PARAM_OPTIMIZE`), a new +transform option (`TJXOPT_OPTIMIZE`/`TJTransform.OPT_OPTIMIZE`), and a new +TJBench option (`-optimize`.) + - Arithmetic entropy coding can now be specified or queried, using a new +API parameter (`TJPARAM_ARITHMETIC`/`TJ.PARAM_ARITHMETIC`), a new transform +option (`TJXOPT_ARITHMETIC`/`TJTransform.OPT_ARITHMETIC`), and a new TJBench +option (`-arithmetic`.) + - The restart marker interval can now be specified, using new API +parameters (`TJPARAM_RESTARTROWS`/`TJ.PARAM_RESTARTROWS` and +`TJPARAM_RESTARTBLOCKS`/`TJ.PARAM_RESTARTBLOCKS`) and a new TJBench option +(`-restart`.) + - Pixel density can now be specified or queried, using new API parameters +(`TJPARAM_XDENSITY`/`TJ.PARAM_XDENSITY`, +`TJPARAM_YDENSITY`/`TJ.PARAM_YDENSITY`, and +`TJPARAM_DENSITYUNITS`/`TJ.PARAM_DENSITYUNITS`.) + - The accurate DCT/IDCT algorithms are now the default for both +compression and decompression, since the "fast" algorithms are considered to be +a legacy feature. (The "fast" algorithms do not pass the ISO compliance tests, +and those algorithms are not any faster than the accurate algorithms on modern +x86 CPUs.) + - All C initialization functions have been combined into a single function +(`tj3Init()`) that accepts an integer argument specifying the subsystems to +initialize. + - All C functions now use the `const` keyword for pointer arguments that +point to unmodified buffers (and for both dimensions of pointer arguments that +point to sets of unmodified buffers.) + - All C functions now use `size_t` rather than `unsigned long` to +represent buffer sizes, for compatibility with `malloc()` and to avoid +disparities in the size of `unsigned long` between LP64 (Un*x) and LLP64 +(Windows) operating systems. + - All C buffer size functions now return 0 if an error occurs, rather than +trying to awkwardly return -1 in an unsigned data type (which could easily be +misinterpreted as a very large value.) + - Decompression scaling is now enabled explicitly, using a new +function/method (`tj3SetScalingFactor()`/`TJDecompressor.setScalingFactor()`), +rather than implicitly using awkward "desired width"/"desired height" +arguments. + - Partial image decompression has been implemented, using a new +function/method (`tj3SetCroppingRegion()`/`TJDecompressor.setCroppingRegion()`) +and a new TJBench option (`-crop`.) + - The JPEG colorspace can now be specified explicitly when compressing, +using a new API parameter (`TJPARAM_COLORSPACE`/`TJ.PARAM_COLORSPACE`.) This +allows JPEG images with the RGB and CMYK colorspaces to be created. + - TJBench no longer generates error/difference images, since identical +functionality is already available in ImageMagick. + - JPEG images with unknown subsampling configurations can now be +fully decompressed into packed-pixel images or losslessly transformed (with the +exception of lossless cropping.) They cannot currently be partially +decompressed or decompressed into planar YUV images. + - `tj3Destroy()` now silently accepts a NULL handle. + - `tj3Alloc()` and `tj3Free()` now return/accept void pointers, as +`malloc()` and `free()` do. + - The C image I/O functions now accept a TurboJPEG instance handle, which +is used to transmit/receive API parameter values and to receive error +information. + +5. Added support for 8-bit-per-component, 12-bit-per-component, and +16-bit-per-component lossless JPEG images. A new libjpeg API function +(`jpeg_enable_lossless()`), TurboJPEG API parameters +(`TJPARAM_LOSSLESS`/`TJ.PARAM_LOSSLESS`, +`TJPARAM_LOSSLESSPSV`/`TJ.PARAM_LOSSLESSPSV`, and +`TJPARAM_LOSSLESSPT`/`TJ.PARAM_LOSSLESSPT`), and a cjpeg/TJBench option +(`-lossless`) can be used to create a lossless JPEG image. (Decompression of +lossless JPEG images is handled automatically.) Refer to +[libjpeg.txt](libjpeg.txt), [usage.txt](usage.txt), and the TurboJPEG API +documentation for more details. + +6. Added support for 12-bit-per-component (lossy and lossless) and +16-bit-per-component (lossless) JPEG images to the libjpeg and TurboJPEG APIs: + + - The existing `data_precision` field in `jpeg_compress_struct` and +`jpeg_decompress_struct` has been repurposed to enable the creation of +12-bit-per-component and 16-bit-per-component JPEG images or to detect whether +a 12-bit-per-component or 16-bit-per-component JPEG image is being +decompressed. + - New 12-bit-per-component and 16-bit-per-component versions of +`jpeg_write_scanlines()` and `jpeg_read_scanlines()`, as well as new +12-bit-per-component versions of `jpeg_write_raw_data()`, +`jpeg_skip_scanlines()`, `jpeg_crop_scanline()`, and `jpeg_read_raw_data()`, +provide interfaces for compressing from/decompressing to 12-bit-per-component +and 16-bit-per-component packed-pixel and planar YUV image buffers. + - New 12-bit-per-component and 16-bit-per-component compression, +decompression, and image I/O functions/methods have been added to the TurboJPEG +API, and a new API parameter (`TJPARAM_PRECISION`/`TJ.PARAM_PRECISION`) can be +used to query the data precision of a JPEG image. (YUV functions are currently +limited to 8-bit data precision but can be expanded to accommodate 12-bit data +precision in the future, if such is deemed beneficial.) + - A new cjpeg and TJBench command-line argument (`-precision`) can be used +to create a 12-bit-per-component or 16-bit-per-component JPEG image. +(Decompression and transformation of 12-bit-per-component and +16-bit-per-component JPEG images is handled automatically.) + + Refer to [libjpeg.txt](libjpeg.txt), [usage.txt](usage.txt), and the +TurboJPEG API documentation for more details. + + +2.1.5.1 +======= + +### Significant changes relative to 2.1.5: + +1. The SIMD dispatchers in libjpeg-turbo 2.1.4 and prior stored the list of +supported SIMD instruction sets in a global variable, which caused an innocuous +race condition whereby the variable could have been initialized multiple times +if `jpeg_start_*compress()` was called simultaneously in multiple threads. +libjpeg-turbo 2.1.5 included an undocumented attempt to fix this race condition +by making the SIMD support variable thread-local. However, that caused another +issue whereby, if `jpeg_start_*compress()` was called in one thread and +`jpeg_read_*()` or `jpeg_write_*()` was called in a second thread, the SIMD +support variable was never initialized in the second thread. On x86 systems, +this led the second thread to incorrectly assume that AVX2 instructions were +always available, and when it attempted to use those instructions on older x86 +CPUs that do not support them, an illegal instruction error occurred. The SIMD +dispatchers now ensure that the SIMD support variable is initialized before +dispatching based on its value. + + +2.1.5 +===== + +### Significant changes relative to 2.1.4: + +1. Fixed issues in the build system whereby, when using the Ninja Multi-Config +CMake generator, a static build of libjpeg-turbo (a build in which +`ENABLE_SHARED` is `0`) could not be installed, a Windows installer could not +be built, and the Java regression tests failed. + +2. Fixed a regression introduced by 2.0 beta1[15] that caused a buffer overrun +in the progressive Huffman encoder when attempting to transform a +specially-crafted malformed 12-bit-per-component JPEG image into a progressive +12-bit-per-component JPEG image using a 12-bit-per-component build of +libjpeg-turbo (`-DWITH_12BIT=1`.) Given that the buffer overrun was fully +contained within the progressive Huffman encoder structure and did not cause a +segfault or other user-visible errant behavior, given that the lossless +transformer (unlike the decompressor) is not generally exposed to arbitrary +data exploits, and given that 12-bit-per-component builds of libjpeg-turbo are +uncommon, this issue did not likely pose a security risk. + +3. Fixed an issue whereby, when using a 12-bit-per-component build of +libjpeg-turbo (`-DWITH_12BIT=1`), passing samples with values greater than 4095 +or less than 0 to `jpeg_write_scanlines()` caused a buffer overrun or underrun +in the RGB-to-YCbCr color converter. + +4. Fixed a floating point exception that occurred when attempting to use the +jpegtran `-drop` and `-trim` options to losslessly transform a +specially-crafted malformed JPEG image. + +5. Fixed an issue in `tjBufSizeYUV2()` whereby it returned a bogus result, +rather than throwing an error, if the `align` parameter was not a power of 2. +Fixed a similar issue in `tjCompressFromYUV()` whereby it generated a corrupt +JPEG image in certain cases, rather than throwing an error, if the `align` +parameter was not a power of 2. + +6. Fixed an issue whereby `tjDecompressToYUV2()`, which is a wrapper for +`tjDecompressToYUVPlanes()`, used the desired YUV image dimensions rather than +the actual scaled image dimensions when computing the plane pointers and +strides to pass to `tjDecompressToYUVPlanes()`. This caused a buffer overrun +and subsequent segfault if the desired image dimensions exceeded the scaled +image dimensions. + +7. Fixed an issue whereby, when decompressing a 12-bit-per-component JPEG image +(`-DWITH_12BIT=1`) using an alpha-enabled output color space such as +`JCS_EXT_RGBA`, the alpha channel was set to 255 rather than 4095. + +8.

      YUV Image Format Notes

      Technically, the JPEG format uses the YCbCr colorspace (which is technically not a colorspace but a color transform), but per the convention of the digital video community, the TurboJPEG API uses "YUV" to refer to an image format consisting of Y, Cb, and Cr image planes.

      -

      Each plane is simply a 2D array of bytes, each byte representing the value of one of the components (Y, Cb, or Cr) at a particular location in the image. The width and height of each plane are determined by the image width, height, and level of chrominance subsampling. The luminance plane width is the image width padded to the nearest multiple of the horizontal subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of 4:1:1, 1 in the case of 4:4:4 or grayscale.) Similarly, the luminance plane height is the image height padded to the nearest multiple of the vertical subsampling factor (2 in the case of 4:2:0 or 4:4:0, 1 in the case of 4:4:4 or grayscale.) This is irrespective of any additional padding that may be specified as an argument to the various YUV functions. The chrominance plane width is equal to the luminance plane width divided by the horizontal subsampling factor, and the chrominance plane height is equal to the luminance plane height divided by the vertical subsampling factor.

      -

      For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is used, then the luminance plane would be 36 x 35 bytes, and each of the chrominance planes would be 18 x 35 bytes. If you specify a line padding of 4 bytes on top of this, then the luminance plane would be 36 x 35 bytes, and each of the chrominance planes would be 20 x 35 bytes.

Originally, the analog equivalent of this transformation allowed the same signal to drive both black & white and color televisions, but JPEG images use YCbCr primarily because it allows the color data to be optionally subsampled for the purposes of reducing bandwidth or disk space. YCbCr is the most common JPEG colorspace, and YCbCr JPEG images can be compressed from and decompressed to any of the extended RGB pixel formats or grayscale, or they can be decompressed to YUV planar images.

JPEG height (in pixels) [decompression only, read-only].

+
TJPARAM_PRECISION 

JPEG data precision (bits per sample) [decompression only, read-only].

+

The JPEG image uses the specified number of bits per sample.

+

Value

    +
  • 8, 12, or 16
    • +
+

12-bit data precision implies TJPARAM_OPTIMIZE unless TJPARAM_ARITHMETIC is set.

+
TJPARAM_COLORSPACE 

JPEG colorspace.

+

The JPEG image uses (decompression) or will use (lossy compression) the specified colorspace.

+

Value

    +
  • One of the JPEG colorspaces [default for lossy compression: automatically selected based on the subsampling level and pixel format]
    • +
+
TJPARAM_FASTUPSAMPLE 

Chrominance upsampling algorithm [lossy decompression only].

+

Value

    +
  • 0 [default] Use smooth upsampling when decompressing a JPEG image that was compressed using chrominance subsampling. This creates a smooth transition between neighboring chrominance components in order to reduce upsampling artifacts in the decompressed image.
    • +
  • 1 Use the fastest chrominance upsampling algorithm available, which may combine upsampling with color conversion.
    • +
+
TJPARAM_FASTDCT 

DCT/IDCT algorithm [lossy compression and decompression].

+

Value

    +
  • 0 [default] Use the most accurate DCT/IDCT algorithm available.
    • +
  • 1 Use the fastest DCT/IDCT algorithm available.
    • +
+

This parameter is provided mainly for backward compatibility with libjpeg, which historically implemented several different DCT/IDCT algorithms because of performance limitations with 1990s CPUs. In the libjpeg-turbo implementation of the TurboJPEG API:

    +
  • The "fast" and "accurate" DCT/IDCT algorithms perform similarly on modern x86/x86-64 CPUs that support AVX2 instructions.
    • +
  • The "fast" algorithm is generally only about 5-15% faster than the "accurate" algorithm on other types of CPUs.
    • +
  • The difference in accuracy between the "fast" and "accurate" algorithms is the most pronounced at JPEG quality levels above 90 and tends to be more pronounced with decompression than with compression.
    • +
  • The "fast" algorithm degrades and is not fully accelerated for JPEG quality levels above 97, so it will be slower than the "accurate" algorithm.
    • +
+
TJPARAM_OPTIMIZE 

Optimized baseline entropy coding [lossy compression only].

+

Value

    +
  • 0 [default] The JPEG image will use the default Huffman tables.
    • +
  • 1 Optimal Huffman tables will be computed for the JPEG image. For lossless transformation, this can also be specified using TJXOPT_OPTIMIZE.
    • +
+

Optimized baseline entropy coding will improve compression slightly (generally 5% or less), but it will reduce compression performance considerably.

+
TJPARAM_PROGRESSIVE 

Progressive entropy coding.

+

Value

    +
  • 0 [default for compression, lossless transformation] The lossy JPEG image uses (decompression) or will use (compression, lossless transformation) baseline entropy coding.
    • +
  • 1 The lossy JPEG image uses (decompression) or will use (compression, lossless transformation) progressive entropy coding. For lossless transformation, this can also be specified using TJXOPT_PROGRESSIVE.
    • +
+

Progressive entropy coding will generally improve compression relative to baseline entropy coding, but it will reduce compression and decompression performance considerably. Can be combined with TJPARAM_ARITHMETIC. Implies TJPARAM_OPTIMIZE unless TJPARAM_ARITHMETIC is also set.

+
TJPARAM_SCANLIMIT 

Progressive JPEG scan limit for lossy JPEG images [decompression, lossless transformation].

+

Setting this parameter will cause the decompression and transform functions to return an error if the number of scans in a progressive JPEG image exceeds the specified limit. The primary purpose of this is to allow security-critical applications to guard against an exploit of the progressive JPEG format described in this report.

+

Value

    +
  • maximum number of progressive JPEG scans that the decompression and transform functions will process [default: 0 (no limit)]
    • +
+
See also
TJPARAM_PROGRESSIVE
+
TJPARAM_ARITHMETIC 

Arithmetic entropy coding.

+

Value

    +
  • 0 [default for compression, lossless transformation] The lossy JPEG image uses (decompression) or will use (compression, lossless transformation) Huffman entropy coding.
    • +
  • 1 The lossy JPEG image uses (decompression) or will use (compression, lossless transformation) arithmetic entropy coding. For lossless transformation, this can also be specified using TJXOPT_ARITHMETIC.
    • +
+

Arithmetic entropy coding will generally improve compression relative to Huffman entropy coding, but it will reduce compression and decompression performance considerably. Can be combined with TJPARAM_PROGRESSIVE.

+
TJPARAM_LOSSLESS 

Lossless JPEG.

+

Value

    +
  • 0 [default for compression] The JPEG image is (decompression) or will be (compression) lossy/DCT-based.
    • +
  • 1 The JPEG image is (decompression) or will be (compression) lossless/predictive.
    • +
+

In most cases, compressing and decompressing lossless JPEG images is considerably slower than compressing and decompressing lossy JPEG images. Also note that the following features are not available with lossless JPEG images:

    +
  • Colorspace conversion (lossless JPEG images always use TJCS_RGB, TJCS_GRAY, or TJCS_CMYK, depending on the pixel format of the source image)
    • +
  • Chrominance subsampling (lossless JPEG images always use TJSAMP_444)
    • +
  • JPEG quality selection
    • +
  • DCT/IDCT algorithm selection
    • +
  • Progressive entropy coding
    • +
  • Arithmetic entropy coding
    • +
  • Compression from/decompression to planar YUV images

TJPARAM_LOSSLESSPT 

Lossless JPEG point transform (Pt)

+

Value

    +
  • 0 through precision - 1, where precision is the JPEG data precision in bits [default for compression: 0]
    • +
+

A point transform value of 0 is necessary in order to generate a fully lossless JPEG image. (A non-zero point transform value right-shifts the input samples by the specified number of bits, which is effectively a form of lossy color quantization.)

+

TJPARAM_LOSSLESS, TJPARAM_PRECISION
+
TJPARAM_RESTARTBLOCKS 

JPEG restart marker interval in MCU blocks (lossy) or samples (lossless) [compression only].

+

The nature of entropy coding is such that a corrupt JPEG image cannot be decompressed beyond the point of corruption unless it contains restart markers. A restart marker stops and restarts the entropy coding algorithm so that, if a JPEG image is corrupted, decompression can resume at the next marker. Thus, adding more restart markers improves the fault tolerance of the JPEG image, but adding too many restart markers can adversely affect the compression ratio and performance.

+

Value

    +
  • the number of MCU blocks or samples between each restart marker [default: 0 (no restart markers)]
    • +
+

Setting this parameter to a non-zero value sets TJPARAM_RESTARTROWS to 0.

+
TJPARAM_RESTARTROWS 

JPEG restart marker interval in MCU rows (lossy) or sample rows (lossless) [compression only].

+

See TJPARAM_RESTARTBLOCKS for a description of restart markers.

+

Value

    +
  • the number of MCU rows or sample rows between each restart marker [default: 0 (no restart markers)]
    • +
+

Setting this parameter to a non-zero value sets TJPARAM_RESTARTBLOCKS to 0.

TJPARAM_XDENSITY 

JPEG horizontal pixel density.

+

Value

    +
  • The JPEG image has (decompression) or will have (compression) the specified horizontal pixel density [default for compression: 1].
    • +
+

This value is stored in or read from the JPEG header. It does not affect the contents of the JPEG image. Note that this parameter is set by tj3LoadImage8() when loading a Windows BMP file that contains pixel density information, and the value of this parameter is stored to a Windows BMP file by tj3SaveImage8() if the value of #TJPARAM_DENSITYUNIT is 2.

In order to convert between CMYK and RGB, it is necessary to use a color management system (CMS.) A CMS will attempt to map colors within the printer's gamut to perceptually similar colors in the display's gamut and vice versa, but the mapping is typically not 1:1 or reversible, nor can it be defined with a simple formula. Thus, such a conversion is out of scope for a codec library.

-

The number of bytes returned by this function is larger than the size of the uncompressed source image. The reason for this is that the JPEG format uses 16-bit coefficients, and it is thus possible for a very high-quality JPEG image with very high-frequency content to expand rather than compress when converted to the JPEG format. Such images represent a very rare corner case, but since there is no way to predict the size of a JPEG image prior to compression, the corner case has to be handled.

jpegBufpointer to a buffer containing the JPEG image to decompress
handlehandle to a TurboJPEG instance that has been initialized for decompression
jpegBufpointer to a byte buffer containing the JPEG image to decompress
jpegSizesize of the JPEG image (in bytes)
dstBufpointer to an image buffer that will receive the decompressed image. This buffer should normally be pitch * scaledHeight bytes in size, where scaledHeight can be determined by calling TJSCALED() with the JPEG image height and one of the scaling factors returned by tjGetScalingFactors(). The dstBuf pointer may also be used to decompress into a specific region of a larger buffer.

If this is different than the width of the JPEG image being decompressed, then TurboJPEG will use scaling in the JPEG decompressor to generate the largest possible image that will fit within the desired width. If width is set to 0, then only the height will be considered when determining the scaled image size.
pitchbytes per line in the destination image. Normally, this is scaledWidth * tjPixelSize[pixelFormat] if the decompressed image is unpadded, else TJPAD(scaledWidth * tjPixelSize[pixelFormat]) if each line of the decompressed image is padded to the nearest 32-bit boundary, as is the case for Windows bitmaps. (NOTE: scaledWidth can be determined by calling TJSCALED() with the JPEG image width and one of the scaling factors returned by tjGetScalingFactors().) You can also be clever and use the pitch parameter to skip lines, etc. Setting this parameter to 0 is the equivalent of setting it to scaledWidth * tjPixelSize[pixelFormat].
heightdesired height (in pixels) of the destination image. If this is different than the height of the JPEG image being decompressed, then TurboJPEG will use scaling in the JPEG decompressor to generate the largest possible image that will fit within the desired height. If height is set to 0, then only the width will be considered when determining the scaled image size.
dstBufpointer to a buffer that will receive the packed-pixel decompressed image. This buffer should normally be pitch * destinationHeight samples in size. However, you can also use this parameter to decompress into a specific region of a larger buffer. NOTE: If the JPEG image is lossy, then destinationHeight is either the scaled JPEG height (see TJSCALED(), TJPARAM_JPEGHEIGHT, and tj3SetScalingFactor()) or the height of the cropping region (see tj3SetCroppingRegion().) If the JPEG image is lossless, then destinationHeight is the JPEG height.
pitchsamples per row in the destination image. Normally this should be set to destinationWidth * tjPixelSize[pixelFormat], if the destination image should be unpadded. (Setting this parameter to 0 is the equivalent of setting it to destinationWidth * tjPixelSize[pixelFormat].) However, you can also use this parameter to specify the row alignment/padding of the destination image, to skip rows, or to decompress into a specific region of a larger buffer.

Retrieve information about a JPEG image without decompressing it, or prime the decompressor with quantization and Huffman tables.

+

Decompress a 16-bit-per-sample lossless JPEG image into a 16-bit-per-sample packed-pixel RGB, grayscale, or CMYK image.

+

The parameters that describe the JPEG image will be set when this function returns.

Parameters
- - - - - - - + + + + + +
handlea handle to a TurboJPEG decompressor or transformer instance
jpegBufpointer to a buffer containing a JPEG image or an "abbreviated table specification" (AKA "tables-only") datastream. Passing a tables-only datastream to this function primes the decompressor with quantization and Huffman tables that can be used when decompressing subsequent "abbreviated image" datastreams. This is useful, for instance, when decompressing video streams in which all frames share the same quantization and Huffman tables.
jpegSizesize of the JPEG image or tables-only datastream (in bytes)
widthpointer to an integer variable that will receive the width (in pixels) of the JPEG image. If jpegBuf points to a tables-only datastream, then width is ignored.
heightpointer to an integer variable that will receive the height (in pixels) of the JPEG image. If jpegBuf points to a tables-only datastream, then height is ignored.
jpegSubsamppointer to an integer variable that will receive the level of chrominance subsampling used when the JPEG image was compressed (see Chrominance subsampling options.) If jpegBuf points to a tables-only datastream, then jpegSubsamp is ignored.
jpegColorspacepointer to an integer variable that will receive one of the JPEG colorspace constants, indicating the colorspace of the JPEG image (see JPEG colorspaces.) If jpegBuf points to a tables-only datastream, then jpegColorspace is ignored.
handlehandle to a TurboJPEG instance that has been initialized for decompression
jpegBufpointer to a byte buffer containing the JPEG image to decompress
jpegSizesize of the JPEG image (in bytes)
dstBufpointer to a buffer that will receive the packed-pixel decompressed image. This buffer should normally be pitch * destinationHeight samples in size. However, you can also use this parameter to decompress into a specific region of a larger buffer. NOTE: If the JPEG image is lossy, then destinationHeight is either the scaled JPEG height (see TJSCALED(), TJPARAM_JPEGHEIGHT, and tj3SetScalingFactor()) or the height of the cropping region (see tj3SetCroppingRegion().) If the JPEG image is lossless, then destinationHeight is the JPEG height.
pitchsamples per row in the destination image. Normally this should be set to destinationWidth * tjPixelSize[pixelFormat], if the destination image should be unpadded. (Setting this parameter to 0 is the equivalent of setting it to destinationWidth * tjPixelSize[pixelFormat].) However, you can also use this parameter to specify the row alignment/padding of the destination image, to skip rows, or to decompress into a specific region of a larger buffer. NOTE: If the JPEG image is lossy, then destinationWidth is either the scaled JPEG width (see TJSCALED(), TJPARAM_JPEGWIDTH, and tj3SetScalingFactor()) or the width of the cropping region (see tj3SetCroppingRegion().)

◆ tj3GetScalingFactors()

+ +
+
+ + + + + + + + +
DLLEXPORT tjscalingfactor* tj3GetScalingFactors (int * numScalingFactors)
+
+ +

Returns a list of fractional scaling factors that the JPEG decompressor supports.

+
Parameters
+ + +
numScalingFactorspointer to an integer variable that will receive the number of elements in the list
+
+
+
Returns
a pointer to a list of fractional scaling factors, or NULL if an error is encountered (see tj3GetErrorStr().)

+
+ +

◆ tj3Init()

+ +
+
+ + + + + + + + +
DLLEXPORT tjhandle tj3Init (int initType)
+
+ +

Create a new TurboJPEG instance.

+
Parameters
+ + +
initTypeone of the initialization options
+
+
+
Returns
a handle to the newly-created instance, or NULL if an error occurred (see tj3GetErrorStr().)
+ +
+
+ +

◆ tj3JPEGBufSize()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
DLLEXPORT size_t tj3JPEGBufSize (int width,
int height,
int jpegSubsamp 
)
+
+ +

The maximum size of the buffer (in bytes) required to hold a JPEG image with the given parameters.

+

The number of bytes returned by this function is larger than the size of the uncompressed source image. The reason for this is that the JPEG format uses 16-bit coefficients, so it is possible for a very high-quality source image with very high-frequency content to expand rather than compress when converted to the JPEG format. Such images represent very rare corner cases, but since there is no way to predict the size of a JPEG image prior to compression, the corner cases have to be handled.

+
Parameters
+ + + + +
widthwidth (in pixels) of the image
heightheight (in pixels) of the image
jpegSubsampthe level of chrominance subsampling to be used when generating the JPEG image (see Chrominance subsampling options.) TJSAMP_UNKNOWN is treated like TJSAMP_444, since a buffer large enough to hold a JPEG image with no subsampling should also be large enough to hold a JPEG image with an arbitrary level of subsampling. Note that lossless JPEG images always use TJSAMP_444.
+
+
+
Returns
the maximum size of the buffer (in bytes) required to hold the image, or 0 if the arguments are out of bounds.

Decompression scaling is a function of the IDCT algorithm, so scaling factors are generally limited to multiples of 1/8. If the entire JPEG image will be decompressed, then the width and height of the scaled destination image can be determined by calling TJSCALED() with the JPEG width and height (see TJPARAM_JPEGWIDTH and TJPARAM_JPEGHEIGHT) and the specified scaling factor. When decompressing into a planar YUV image, an intermediate buffer copy will be performed if the width or height of the scaled destination image is not an even multiple of the MCU block size (see tjMCUWidth and tjMCUHeight.) Note that decompression scaling is not available (and the specified scaling factor is ignored) when decompressing lossless JPEG images (see TJPARAM_LOSSLESS), since the IDCT algorithm is not used with those images. Note also that TJPARAM_FASTDCT is ignored when decompression scaling is enabled.

Losslessly transform a JPEG image into another JPEG image.

+

Lossless transforms work by moving the raw DCT coefficients from one JPEG image structure to another without altering the values of the coefficients. While this is typically faster than decompressing the image, transforming it, and re-compressing it, lossless transforms are not free. Each lossless transform requires reading and performing entropy decoding on all of the coefficients in the source image, regardless of the size of the destination image. Thus, this function provides a means of generating multiple transformed images from the same source or applying multiple transformations simultaneously, in order to eliminate the need to read the source coefficients multiple times.

Parameters
- - - + + + + + + +
componentIDID number of the image plane (0 = Y, 1 = U/Cb, 2 = V/Cr)
heightheight (in pixels) of the YUV image
subsamplevel of chrominance subsampling in the image (see Chrominance subsampling options.)
handlehandle to a TurboJPEG instance that has been initialized for lossless transformation
jpegBufpointer to a byte buffer containing the JPEG source image to transform
jpegSizesize of the JPEG source image (in bytes)
nthe number of transformed JPEG images to generate
dstBufspointer to an array of n byte buffers. dstBufs[i] will receive a JPEG image that has been transformed using the parameters in transforms[i]. TurboJPEG has the ability to reallocate the JPEG destination buffer to accommodate the size of the transformed JPEG image. Thus, you can choose to:
    +
  1. pre-allocate the JPEG destination buffer with an arbitrary size using tj3Alloc() and let TurboJPEG grow the buffer as needed,
    2. +
  2. set dstBufs[i] to NULL to tell TurboJPEG to allocate the buffer for you, or
    3. +
  3. pre-allocate the buffer to a "worst case" size determined by calling tj3JPEGBufSize() with the transformed or cropped width and height and the level of subsampling used in the source image. Under normal circumstances, this should ensure that the buffer never has to be re-allocated. (Setting TJPARAM_NOREALLOC guarantees that it won't be.) Note, however, that there are some rare cases (such as transforming images with a large amount of embedded EXIF or ICC profile data) in which the transformed JPEG image will be larger than the worst-case size, and TJPARAM_NOREALLOC cannot be used in those cases.
    4. +
+If you choose option 1, then dstSizes[i] should be set to the size of your pre-allocated buffer. In any case, unless you have set TJPARAM_NOREALLOC, you should always check dstBufs[i] upon return from this function, as it may have changed.
dstSizespointer to an array of n size_t variables that will receive the actual sizes (in bytes) of each transformed JPEG image. If dstBufs[i] points to a pre-allocated buffer, then dstSizes[i] should be set to the size of the buffer. Upon return, dstSizes[i] will contain the size of the transformed JPEG image (in bytes.)
transformspointer to an array of n tjtransform structures, each of which specifies the transform parameters and/or cropping region for the corresponding transformed JPEG image.

Save an uncompressed image from memory to disk.

+

The size of the buffer (in bytes) required to hold a YUV image plane with the given parameters.

Parameters
- - - - - - - + + + + +
filenamename of a file to which to save the uncompressed image. The image will be stored in Windows BMP or PBMPLUS (PPM/PGM) format, depending on the file extension.
bufferpointer to an image buffer containing RGB, grayscale, or CMYK pixels to be saved
widthwidth (in pixels) of the uncompressed image
pitchbytes per line in the image buffer. Setting this parameter to 0 is the equivalent of setting it to width * tjPixelSize[pixelFormat].
heightheight (in pixels) of the uncompressed image
pixelFormatpixel format of the image buffer (see Pixel formats.) If this parameter is set to TJPF_GRAY, then the image will be stored in PGM or 8-bit (indexed color) BMP format. Otherwise, the image will be stored in PPM or 24-bit BMP format. If this parameter is set to TJPF_CMYK, then the CMYK pixels will be converted to RGB using a quick & dirty algorithm that is suitable only for testing (proper conversion between CMYK and other formats requires a color management system.)
flagsthe bitwise OR of one or more of the flags.
componentIDID number of the image plane (0 = Y, 1 = U/Cb, 2 = V/Cr)
widthwidth (in pixels) of the YUV image. NOTE: this is the width of the whole image, not the plane width.
stridebytes per row in the image plane. Setting this to 0 is the equivalent of setting it to the plane width.
heightheight (in pixels) of the YUV image. NOTE: this is the height of the whole image, not the plane height.
subsamplevel of chrominance subsampling in the image (see Chrominance subsampling options.)
-
Returns
0 if successful, or -1 if an error occurred (see tjGetErrorStr2().)
+
Returns
the size of the buffer (in bytes) required to hold the YUV image plane, or 0 if the arguments are out of bounds.

Losslessly transform a JPEG image into another JPEG image.

-

Lossless transforms work by moving the raw DCT coefficients from one JPEG image structure to another without altering the values of the coefficients. While this is typically faster than decompressing the image, transforming it, and re-compressing it, lossless transforms are not free. Each lossless transform requires reading and performing Huffman decoding on all of the coefficients in the source image, regardless of the size of the destination image. Thus, this function provides a means of generating multiple transformed images from the same source or applying multiple transformations simultaneously, in order to eliminate the need to read the source coefficients multiple times.

+

The plane width of a YUV image plane with the given parameters.

+

Refer to YUV Image Format Notes for a description of plane width.

Parameters
- - - - - - - - + + +
handlea handle to a TurboJPEG transformer instance
jpegBufpointer to a buffer containing the JPEG source image to transform
jpegSizesize of the JPEG source image (in bytes)
nthe number of transformed JPEG images to generate
dstBufspointer to an array of n image buffers. dstBufs[i] will receive a JPEG image that has been transformed using the parameters in transforms[i]. TurboJPEG has the ability to reallocate the JPEG buffer to accommodate the size of the JPEG image. Thus, you can choose to:
    -
  1. pre-allocate the JPEG buffer with an arbitrary size using tjAlloc() and let TurboJPEG grow the buffer as needed,
    2. -
  2. set dstBufs[i] to NULL to tell TurboJPEG to allocate the buffer for you, or
    3. -
  3. pre-allocate the buffer to a "worst case" size determined by calling tjBufSize() with the transformed or cropped width and height. Under normal circumstances, this should ensure that the buffer never has to be re-allocated (setting TJFLAG_NOREALLOC guarantees that it won't be.) Note, however, that there are some rare cases (such as transforming images with a large amount of embedded EXIF or ICC profile data) in which the output image will be larger than the worst-case size, and TJFLAG_NOREALLOC cannot be used in those cases.
    4. -
-If you choose option 1, dstSizes[i] should be set to the size of your pre-allocated buffer. In any case, unless you have set TJFLAG_NOREALLOC, you should always check dstBufs[i] upon return from this function, as it may have changed.
dstSizespointer to an array of n unsigned long variables that will receive the actual sizes (in bytes) of each transformed JPEG image. If dstBufs[i] points to a pre-allocated buffer, then dstSizes[i] should be set to the size of the buffer. Upon return, dstSizes[i] will contain the size of the JPEG image (in bytes.)
transformspointer to an array of n tjtransform structures, each of which specifies the transform parameters and/or cropping region for the corresponding transformed output image.
flagsthe bitwise OR of one or more of the flags
componentIDID number of the image plane (0 = Y, 1 = U/Cb, 2 = V/Cr)
widthwidth (in pixels) of the YUV image
subsamplevel of chrominance subsampling in the image (see Chrominance subsampling options.)

        Class or Interface

        Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:

        Tree (Class Hierarchy)

        -

        There is a Class Hierarchy page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with java.lang.Object. The interfaces do not inherit from java.lang.Object.

        Deprecated API

        The Deprecated API page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.

        Serialized Form

        Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.

        Constant Field Values

        The Constant Field Values page lists the static final fields and their values.

        setSubsamp

        -
        public void setSubsamp(int newSubsamp)
        -
        Set the level of chrominance subsampling for subsequent compress/encode - operations. When pixels are converted from RGB to YCbCr (see - TJ.CS_YCbCr) or from CMYK to YCCK (see TJ.CS_YCCK) as part - of the JPEG compression process, some of the Cb and Cr (chrominance) - components can be discarded or averaged together to produce a smaller - image with little perceptible loss of image clarity (the human eye is more - sensitive to small changes in brightness than to small changes in color.) - This is called "chrominance subsampling". -

        - NOTE: This method has no effect when compressing a JPEG image from a YUV - planar source. In that case, the level of chrominance subsampling in - the JPEG image is determined by the source. Furthermore, this method has - no effect when encoding to a pre-allocated YUVImage instance. In - that case, the level of chrominance subsampling is determined by the - destination.

        -
        Parameters:
        newSubsamp - the level of chrominance subsampling to use in - subsequent compress/encode oeprations (one of - TJ.SAMP_*)

            +
            Parameters:
            +
            scalingFactor - TJScalingFactor instance that specifies a + fractional scaling factor that the decompressor supports (see + TJ.getScalingFactors()), or TJ.UNSCALED for no scaling. + Decompression scaling is a function of the IDCT algorithm, so scaling + factors are generally limited to multiples of 1/8. If the entire JPEG + image will be decompressed, then the width and height of the scaled + destination image can be determined by calling + scalingFactor.getScaled() + with the JPEG image width and height (see getWidth() and + getHeight().) When decompressing into a planar YUV image, an + intermediate buffer copy will be performed if the width or height of the + scaled destination image is not an even multiple of the MCU block size + (see TJ.getMCUWidth() and TJ.getMCUHeight().) Note that decompression scaling is not available + (and the specified scaling factor is ignored) when decompressing lossless + JPEG images (see TJ.PARAM_LOSSLESS), since the IDCT algorithm is + not used with those images. Note also that TJ.PARAM_FASTDCT is + ignored when decompression scaling is enabled.

However, the buffer + may also be larger, in which case the x, y, and + pitch parameters can be used to specify the region into which + the source image should be decompressed/decoded. NOTE: If the source + image is a lossy JPEG image, then destinationHeight is either + the scaled JPEG height (see setScalingFactor(), + TJScalingFactor.getScaled(), and + getHeight()) or the height of the cropping region (see + setCroppingRegion().) If the source image is a + YUV image or a lossless JPEG image, then destinationHeight is + the height of the source image.
              +
              x - x offset (in pixels) of the region in the destination image into + which the source image should be decompressed/decoded
              +
              y - y offset (in pixels) of the region in the destination image into + which the source image should be decompressed/decoded
              +
              pitch - bytes per row in the destination image. Normally this should + be set to destinationWidth * + TJ.getPixelSize(pixelFormat), if the + destination image will be unpadded. (Setting this parameter to 0 is the + equivalent of setting it to destinationWidth * + TJ.getPixelSize(pixelFormat).) However, + you can also use this parameter to specify the row alignment/padding of + the destination image, to skip rows, or to decompress/decode into a + specific region of a larger image. NOTE: if the source image is a lossy + JPEG image, then destinationWidth is either the scaled JPEG + width (see setScalingFactor(), + TJScalingFactor.getScaled(), and + getWidth()) or the width of the cropping region (see + setCroppingRegion().) If the source image is a + YUV image or a lossless JPEG image, then destinationWidth is + the width of the source image.

              dstBuf - buffer that will receive the packed-pixel + decompressed image. This buffer should normally be + pitch * destinationHeight samples in size. However, the + buffer may also be larger, in which case the x, + y, and pitch parameters can be used to specify + the region into which the source image should be decompressed. NOTE: If + the source image is a lossy JPEG image, then + destinationHeight is either the scaled JPEG height (see + setScalingFactor(), + TJScalingFactor.getScaled(), and + getHeight()) or the height of the cropping region (see + setCroppingRegion().)

              y - y offset (in pixels) of the region in the destination image into + which the source image should be decompressed
              +
              pitch - samples per row in the destination image. Normally this + should be set to destinationWidth * + TJ.getPixelSize(pixelFormat), if the + destination image will be unpadded. (Setting this parameter to 0 is the + equivalent of setting it to destinationWidth * + TJ.getPixelSize(pixelFormat).) However, + you can also use this parameter to specify the row alignment/padding of + the destination image, to skip rows, or to decompress into a specific + region of a larger image. NOTE: if the source image is a lossy JPEG + image, then destinationWidth is either the scaled JPEG width + (see setScalingFactor(), + TJScalingFactor.getScaled(), and + getWidth()) or the width of the cropping region (see + setCroppingRegion().)

-                throws TJException
              -
              Decompress the JPEG source image or decode the YUV source image associated - with this decompressor instance and output a grayscale, RGB, or CMYK image - to the given destination buffer. -

              - NOTE: The output image is fully recoverable if this method throws a - non-fatal TJException (unless - TJ.FLAG_STOPONWARNING is specified.)

              -
              Parameters:
              dstBuf - buffer that will receive the decompressed/decoded image. - If the source image is a JPEG image, then this buffer should normally be - pitch * scaledHeight bytes in size, where - scaledHeight can be determined by calling - scalingFactor.getScaled(jpegHeight) - with one of the scaling factors returned from TJ.getScalingFactors() or by calling getScaledHeight(int, int). If the - source image is a YUV image, then this buffer should normally be - pitch * height bytes in size, where height is - the height of the YUV image. However, the buffer may also be larger than - the dimensions of the source image, in which case the x, - y, and pitch parameters can be used to specify - the region into which the source image should be decompressed/decoded.
              x - x offset (in pixels) of the region in the destination image into - which the source image should be decompressed/decoded
              y - y offset (in pixels) of the region in the destination image into - which the source image should be decompressed/decoded
              desiredWidth - If the source image is a JPEG image, then this - specifies the desired width (in pixels) of the decompressed image (or - image region.) If the desired destination image dimensions are different - than the source image dimensions, then TurboJPEG will use scaling in the - JPEG decompressor to generate the largest possible image that will fit - within the desired dimensions. Setting this to 0 is the same as setting - it to the width of the JPEG image (in other words, the width will not be - considered when determining the scaled image size.) This parameter is - ignored if the source image is a YUV image.
              pitch - bytes per line of the destination image. Normally, this - should be set to scaledWidth * TJ.pixelSize(pixelFormat) if - the destination image is unpadded, but you can use this to, for instance, - pad each line of the destination image to a 4-byte boundary or to - decompress/decode the source image into a region of a larger image. NOTE: - if the source image is a JPEG image, then scaledWidth can be - determined by calling - scalingFactor.getScaled(jpegWidth) - or by calling getScaledWidth(int, int). If the source image is a - YUV image, then scaledWidth is the width of the YUV image. - Setting this parameter to 0 is the equivalent of setting it to - scaledWidth * TJ.pixelSize(pixelFormat).
              desiredHeight - If the source image is a JPEG image, then this - specifies the desired height (in pixels) of the decompressed image (or - image region.) If the desired destination image dimensions are different - than the source image dimensions, then TurboJPEG will use scaling in the - JPEG decompressor to generate the largest possible image that will fit - within the desired dimensions. Setting this to 0 is the same as setting - it to the height of the JPEG image (in other words, the height will not be - considered when determining the scaled image size.) This parameter is - ignored if the source image is a YUV image.
              pixelFormat - pixel format of the decompressed/decoded image (one of - TJ.PF_*)
              flags - the bitwise OR of one or more of - TJ.FLAG_*

              -
              Parameters:
              desiredWidth - desired width (in pixels) of the YUV image. If the - desired image dimensions are different than the dimensions of the JPEG - image being decompressed, then TurboJPEG will use scaling in the JPEG - decompressor to generate the largest possible image that will fit within - the desired dimensions. Setting this to 0 is the same as setting it to - the width of the JPEG image (in other words, the width will not be - considered when determining the scaled image size.)
              strides - an array of integers, each specifying the number of bytes - per line in the corresponding plane of the output image. Setting the - stride for any plane to 0 is the same as setting it to the scaled - component width of the plane. If strides is NULL, then the - strides for all planes will be set to their respective scaled component - widths. You can adjust the strides in order to add an arbitrary amount of - line padding to each plane.

              - NOTE: The output image is fully recoverable if this method throws a - non-fatal TJException (unless - TJ.FLAG_STOPONWARNING is specified.)

              -
              Parameters:
              dstBuf - buffer that will receive the decompressed/decoded image. - If the source image is a JPEG image, then this buffer should normally be - stride * scaledHeight pixels in size, where - scaledHeight can be determined by calling - scalingFactor.getScaled(jpegHeight) - with one of the scaling factors returned from TJ.getScalingFactors() or by calling getScaledHeight(int, int). If the - source image is a YUV image, then this buffer should normally be - stride * height pixels in size, where height is - the height of the YUV image. However, the buffer may also be larger than - the dimensions of the JPEG image, in which case the x, - y, and stride parameters can be used to specify - the region into which the source image should be decompressed.
              x - x offset (in pixels) of the region in the destination image into - which the source image should be decompressed/decoded
              y - y offset (in pixels) of the region in the destination image into - which the source image should be decompressed/decoded
              desiredWidth - If the source image is a JPEG image, then this - specifies the desired width (in pixels) of the decompressed image (or - image region.) If the desired destination image dimensions are different - than the source image dimensions, then TurboJPEG will use scaling in the - JPEG decompressor to generate the largest possible image that will fit - within the desired dimensions. Setting this to 0 is the same as setting - it to the width of the JPEG image (in other words, the width will not be - considered when determining the scaled image size.) This parameter is - ignored if the source image is a YUV image.
              stride - pixels per line of the destination image. Normally, this - should be set to scaledWidth, but you can use this to, for - instance, decompress the JPEG image into a region of a larger image. - NOTE: if the source image is a JPEG image, then scaledWidth - can be determined by calling - scalingFactor.getScaled(jpegWidth) - or by calling getScaledWidth(int, int). If the source image is a - YUV image, then scaledWidth is the width of the YUV image. - Setting this parameter to 0 is the equivalent of setting it to - scaledWidth.
              desiredHeight - If the source image is a JPEG image, then this - specifies the desired height (in pixels) of the decompressed image (or - image region.) If the desired destination image dimensions are different - than the source image dimensions, then TurboJPEG will use scaling in the - JPEG decompressor to generate the largest possible image that will fit - within the desired dimensions. Setting this to 0 is the same as setting - it to the height of the JPEG image (in other words, the height will not be - considered when determining the scaled image size.) This parameter is - ignored if the source image is a YUV image.
              pixelFormat - pixel format of the decompressed image (one of - TJ.PF_*)
              flags - the bitwise OR of one or more of - TJ.FLAG_*

    +
    +
    Parameters:
    +
    dstBuf - buffer that will receive the packed-pixel + decompressed/decoded image. This buffer should normally be + stride * destinationHeight pixels in size. However, the + buffer may also be larger, in which case the x, + y, and pitch parameters can be used to specify + the region into which the source image should be decompressed/decoded. + NOTE: If the source image is a lossy JPEG image, then + destinationHeight is either the scaled JPEG height (see + setScalingFactor(), + TJScalingFactor.getScaled(), and + getHeight()) or the height of the cropping region (see + setCroppingRegion().) If the source image is a + YUV image or a lossless JPEG image, then destinationHeight is + the height of the source image.
    +
    x - x offset (in pixels) of the region in the destination image into + which the source image should be decompressed/decoded
    +
    y - y offset (in pixels) of the region in the destination image into + which the source image should be decompressed/decoded
    +
    stride - pixels per row in the destination image. Normally this + should be set to destinationWidth. (Setting this parameter + to 0 is the equivalent of setting it to destinationWidth.) + However, you can also use this parameter to skip rows or to + decompress/decode into a specific region of a larger image. NOTE: if the + source image is a lossy JPEG image, then destinationWidth is + either the scaled JPEG width (see setScalingFactor(), TJScalingFactor.getScaled(), and getWidth()) or the width of the + cropping region (see setCroppingRegion().) If + the source image is a YUV image or a lossless JPEG image, then + destinationWidth is the width of the source image.

Lossless transforms operate on MCU blocks, whose size depends on the level of chrominance subsampling used.

      Each plane is simply a 2D array of bytes, each byte representing the value of one of the components (Y, Cb, or Cr) at a particular location in the image. The width and height of each plane are determined by the image width, height, and level of chrominance subsampling. The luminance plane width is the image width padded to the nearest multiple of the horizontal - subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of - 4:1:1, 1 in the case of 4:4:4 or grayscale.)

      For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is used, then the luminance plane would be 36 x 35 bytes, and each of the - chrominance planes would be 18 x 35 bytes.
