* Get rid of leaks in SkCodec::NewFromStream.Gravatar scroggo2015-04-03
| | | | | | | | | | | | | | | | | | | | 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, which will report that we leaked something without the other changes. BUG=skia:3257 Review URL: https://codereview.chromium.org/1058873006

* Add a method to read a stream without advancing it.Gravatar scroggo2015-04-02
| | | | | | | | | | | | | | | | | | | | | Add a virtual method on SkStream which will do a "peek" some bytes, so that those bytes are read, but the next call to read will be unaffected. Implement peek for SkMemoryStream, where the implementation is simple and obvious. Implement peek on SkFrontBufferedStream. Add tests. Motivated by decoding streams which cannot be rewound.

* Implement approx-match support in image filter saveLayer() offscreen.Gravatar senorblanco2015-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 - Updated for new SkPDFGraphicState interface. BUG=skia:3585 Review URL: https://codereview.chromium.org/1046293002

* SkPDF: Factor SkPDFCatalog into SkPDFObjNumMap and SkPDFSubstituteMapGravatar halcanary2015-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | Motivation: Keep separate features separate. Also, future linearization work will need to have several objNumMap objects share a substituteMap. Also "catalog" has a specific meaning in PDF. This catalog did not map to that catalog. - Modify SkPDFObject::emitObject and SkPDFObject::addResources interface to requiore SkPDFObjNumMap and SkPDFSubstituteMap. - SkPDFObjNumMap const in SkPDFObject::emitObject. - Remove SkPDFCatalog.cpp/.h - Modify SkDocument_PDF.cpp to use new functions - Fold in SkPDFStream::populate - Fold in SkPDFBitmap::emitDict - Move SkPDFObjNumMap and SkPDFSubstituteMap to SkPDFTypes.h - Note (via assert) that SkPDFArray & SkPDFDict don't need to check substitutes. - Remove extra space from SkPDFDict serialization. - SkPDFBitmap SkPDFType0Font SkPDFGraphicState SkPDFStream updated to new interface. - PDFPrimitivesTest updated for new interface.

* Implement approx-match support in image filter saveLayer() offscreen.Gravatar senorblanco2015-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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): matriximagefilter, matrixconvolution, imagefiltersscaled, lighting, imagemagnifier, filterfastbounds, complexclip_aa_Layer_invert, complexclip_aa_layer, complexclip_bw_layer_invert, complexclip_bw_layer.

* Refactor Sk2x<T> + Sk4x<T> into SkNf<N,T> and SkNi<N,T>Gravatar mtklein2015-03-30
| | | | | | | | | | | | | | | | | | | | | The primary feature this delivers is SkNf and SkNd for arbitrary power-of-two N. Non-specialized types or types larger than 128 bits should now Just Work (and we can drop in a specialization to make them faster). Sk4s is now just a typedef for SkNf<4, SkScalar>; Sk4d is SkNf<4, double>, Sk2f SkNf<2, float>, etc. This also makes implementing new specializations easier and more encapsulated. We're now using template specialization, which means the specialized versions don't have to leak out so much from SkNx_sse.h and SkNx_neon.h. This design leaves us room to grow up, e.g to SkNf<8, SkScalar> == Sk8s, and to grown down too, to things like SkNi<8, uint16_t> == Sk8h. To simplify things, I've stripped away most APIs (swizzles, casts, reinterpret_casts) that no one's using yet. I will happily add them back if they seem useful. You shouldn't feel bad about using any of the typedef Sk4s, Sk4f, Sk4d, Sk2s, Sk2f, Sk2d, Sk4i, etc. Here's how you should feel: - Sk4f, Sk4s, Sk2d: feel awesome - Sk2f, Sk2s, Sk4d: feel pretty good No public API changes.
