Get rid of leaks in SkCodec::NewFromStream.

SkCodec::NewFromStream claims to delete the passed in SkStream on
failure. This allows the caller to pass an SkStream to the function
and not worry about deleting it depending on the return value.

Most of our SkCodecs did not honor this contract though. Update them
to delete the stream on failure. Further, update SkCodec::NewFromStream
to delete the stream if it did not match any subclass, and delete the
SkCodec if we decided to return NULL because it was too big.

Add a test which tests streams which represent the beginnings of
supported format types but do not contain enough data to create an
SkCodec. The interesting part of the test is when we run it on ASAN,

9 years agoImplement approx-match support in image filter saveLayer() offscreen.
senorblanco [Thu, 2 Apr 2015 11:54:56 +0000 (04:54 -0700)]
Implement approx-match support in image filter saveLayer() offscreen.

Currently, the GPU-side image filter implementation creates
exact-match textures for the offscreen backing stores for
saveLayer().  This is because several filters have GPU
implementations which depend on the texture coordinates
being 0..1.

The fix is three-fold:

1) Store the actual requested size in the SkGpuDevice, so
that when wrapping it in an SkBitmap for passing to
filterImage(), we can give it the original size.
2) Fix the filters (SkMagnifierImageFilter,
SkLightingImageFilter, SkMatrixConvolutionImageFilter,
SkMatrixImageFilter) whose GPU implementation depends on
0..1 texture coordinates.
3) Remove the exception for GPU-side image filters in
SkCanvas::internalSaveLayer().

For the lighting filters, there were two bugs which were
cancelling each other out: the sobel filter matrix was
being computed upside down, but then we'd negate the
resulting normal. This worked fine in the exact-match case,
but in the approx-match case we'd sample garbage along
the edge pixels. Also, we never implemented the edge pixels
according to spec in the GPU case. It requires a
different fragment shader for each edge of the nine-patch,
which meant we couldn't use asFragmentProcessor(), and had
to implement the drawing via a filterImageGPU() override.
In order to avoid polluting the public API, I inserted a
new base class, SkLightingImageFilterInternal above
Sk[Diffuse|Specular]LightingImageFilter to handle the
implementation.

For the SkMatrixConvolutionImageFilter, it seems the
GLSL clamp() function occasionally returns values outside
the clamped range, resulting in access of garbage
texels even in GL_NEAREST. The fix here is to clamp to a
rect inset by half a texel. There was also a bug in
the unpremultiply step when fConvolveAlpha is false.

For SkMatrixImageFilter, the fix was to make the generic
draw path be more careful about when to use texture domain.
If the bitmap already has a texture, use texture domain
if the srcRect is smaller than the entire texture (not
the entire bitmap).

N.B.: this change will cause some minor pixel diffs in the
GPU results of the following GMs (and possibly more):
matriximagefilter, matrixconvolution, imagefiltersscaled,
lighting, imagemagnifier, filterfastbounds,
complexclip_aa_Layer_invert, complexclip_aa_layer,
complexclip_bw_layer_invert, complexclip_bw_layer.

SkPDF: SkPDFGraphicState Lookup hashtabled

In Release, running `dm --src skp --config pdf`, I get a
speedup of about 1.2%.

SkPDFGraphicState class:
-   Holds the subset of SkPaint that maps to a PDF Graphics
    State
-   These fields are easily comparable, making hashtable
    comparisons easy.

SkPDFCanon:
-   findGraphicState() takes a SkPDFGraphicState, not a SkPaint
-   fGraphicStateRecords is a SkHashSet, not a SkTDArray

SkPDFGraphicState:
-   mode_for_pdf() replaces logic inside equivalent(), but is
    only called once per lookup.
-   emitObject() no longer modifies the SkPDFGraphicState to
    cache the SkPDFDict stucture.  (Since it is de-duped,
    this get no speedup).
-   Static Functions that don't use the canon return a plain
    SkPDFDict now.  No need for fPopulated.

SkTHash.h
-   SkHashSet::forall added

SkPDFDevice; SkPDFShader

9 years agoImplement approx-match support in image filter saveLayer() offscreen.
senorblanco [Tue, 31 Mar 2015 15:35:15 +0000 (08:35 -0700)]
Implement approx-match support in image filter saveLayer() offscreen.

Currently, the GPU-side image filter implementation creates
exact-match textures for the offscreen backing stores for
saveLayer().  This is because several filters have GPU
implementations which depend on the texture coordinates
being 0..1.

The fix is three-fold:

1) Store the actual requested size in the SkGpuDevice, so
that when wrapping it in an SkBitmap for passing to
filterImage(), we can give it the original size.
2) Fix the filters (SkMagnifierImageFilter,
SkLightingImageFilter) whose GPU implementation depends on
0..1 texture coordinates.
3) Remove the exception for GPU-side image filters in
SkCanvas::internalSaveLayer().

For the lighting filters, there were two bugs which were
cancelling each other out: the sobel filter matrix was
being computed upside down, but then we'd negate the
resulting normal. This worked fine in the exact-match case,
but in the approx-match case we'd sample garbage along
the edge pixels. Also, we never implemented the edge pixels
according to spec in the GPU case. It requires a
different fragment shader for each edge of the nine-patch,
which meant we couldn't use asFragmentProcessor(), and had
to implement the drawing via a filterImageGPU() override.
In order to avoid polluting the public API, I inserted a
new base class, SkLightingImageFilterInternal above
Sk[Diffuse|Specular]LightingImageFilter to handle the
implementation.

N.B.: this change will cause some minor pixel diffs in the
GPU results of the following GMs (and possibly more):
