26 #ifdef PIXARLOG_SUPPORT
30 * PixarLog Compression Support
32 * Contributed by Dan McCoy.
34 * PixarLog film support uses the TIFF library to store companded
35 * 11 bit values into a tiff file, which are compressed using the
38 * The codec can take as input and produce as output 32-bit IEEE float values
39 * as well as 16-bit or 8-bit unsigned integer values.
41 * On writing any of the above are converted into the internal
42 * 11-bit log format. In the case of 8 and 16 bit values, the
43 * input is assumed to be unsigned linear color values that represent
44 * the range 0-1. In the case of IEEE values, the 0-1 range is assumed to
45 * be the normal linear color range, in addition over 1 values are
46 * accepted up to a value of about 25.0 to encode "hot" highlights and such.
47 * The encoding is lossless for 8-bit values, slightly lossy for the
48 * other bit depths. The actual color precision should be better
49 * than the human eye can perceive with extra room to allow for
50 * error introduced by further image computation. As with any quantized
51 * color format, it is possible to perform image calculations which
52 * expose the quantization error. This format should certainly be less
53 * susceptible to such errors than standard 8-bit encodings, but more
54 * susceptible than straight 16-bit or 32-bit encodings.
56 * On reading the internal format is converted to the desired output format.
57 * The program can request which format it desires by setting the internal
58 * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values:
59 * PIXARLOGDATAFMT_FLOAT = provide IEEE float values.
60 * PIXARLOGDATAFMT_16BIT = provide unsigned 16-bit integer values
61 * PIXARLOGDATAFMT_8BIT = provide unsigned 8-bit integer values
63 * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer
64 * values with the difference that if there are exactly three or four channels
65 * (rgb or rgba) it swaps the channel order (bgr or abgr).
67 * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly
68 * packed in 16-bit values. However no tools are supplied for interpreting
71 * "hot" (over 1.0) areas written in floating point get clamped to
72 * 1.0 in the integer data types.
74 * When the file is closed after writing, the bit depth and sample format
75 * are set always to appear as if 8-bit data has been written into it.
76 * That way a naive program unaware of the particulars of the encoding
77 * gets the format it is most likely able to handle.
79 * The codec does it's own horizontal differencing step on the coded
80 * values so the libraries predictor stuff should be turned off.
81 * The codec also handle byte swapping the encoded values as necessary
82 * since the library does not have the information necessary
83 * to know the bit depth of the raw unencoded buffer.
85 * NOTE: This decoder does not appear to update tif_rawcp, and tif_rawcc.
86 * This can cause problems with the implementation of CHUNKY_STRIP_READ_SUPPORT
87 * as noted in http://trac.osgeo.org/gdal/ticket/3894. FrankW - Jan'11
