* Fix GIF transparency.Gravatar jei.mayol2015-02-04
| | | | | | | | | | | | | | | | | | | The GIF decoder, in the onDecode() function, tries to obtain the transparency info from the temporary SavedImage object, temp_save, but the decoder had been changed to save extension block data to the GifFileType object instead. As a result, find_transpIndex() can't find the correct transaprency index and returns -1. This had been reported in Android 4.4. AOSP pulled skia changes related to giflib 5.x changes after Android 4.3, which is why the problem is not reproducible in versions before KitKat.

* Upstream support for giflib >= 5.1.Gravatar mtklein2015-01-20
| | | | | | | | | | | | | | DGifCloseFile now takes two arugments. The second argument appears to be an optional out-param with more information on failures. ( c.f. http://giflib.sourceforge.net/gif_lib.html ) PS 1 is the original patch we received from google3. I've updated it a bit to be pedantically legal C++98.

* Qualify the return value of SkImageDecoder::decodeGravatar scroggo2014-10-22
| | | | | | | | | | | | | | | | | | | | | | | Add a new enum to differentiate between a complete decode and a partial decode (with the third value being failure). Return this value from SkImageDecoder::onDecode (in all subclasses, plus SkImageDecoder_empty) and ::decode. For convenience, if the enum is treated as a boolean, success and partial success are both considered true. Note that the static helper functions (DecodeFile etc) still return true and false (for one thing, this allows us to continue to use SkImageDecoder::DecodeMemory as an SkPicture::InstallPixelRefProc in SkPicture::CreateFromStream). Also correctly report failure in SkASTCImageDecoder::onDecode when SkTextureCompressor::DecompressBufferFromFormat fails.

* Sanitize bitmaps produced by libgifGravatar halcanary@google.com2013-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Motivation: fix the bug linked to below. Some rare GIFs in the wild have a color table of size smaller than 256 and have one or more pixels with values that index out side of the colortable. Since it would be expensive to check the index every time we do a color lookup, we sanitize it at the source, in SkImageDecoder_libgif.cpp. The new function sanitize_indexed_bitmap checks each pixel to see if the index is outside of its allowed mask, and if so, sets that pixel to point at color 0. The bit mask optimization in this function relies on the fact that GIF requires the color table size to be a power of 2. To test: $ skia_images_gif_suppressDecoderWarnings=0 \ ..../render_pictures \ --bbh grid 256 256 --clone 1 --config 8888 --mode tile 256 256 \ -r ..../http___www_cafe24_com_.skp -w /tmp This should show verbose errors.

* GIF decode: optional error messages and fault tolerance.Gravatar halcanary@google.com2013-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new runtime configuration variable, images.gif.suppressDecoderWarnings, which suppresses warning and errors from the GIF library. It defaults to "true", which is current behavior. (This setting can be changed by setting the environment variable skia_images_gif_suppressDecoderWarnings="false".) Some conditions which were errors before are now warnings: - If the image width or height is greater than the GIF screen width or height (respectively) we expand the screen to hold the image. - If the offset of the image inside the screen would place the image outside of the screen, we shift the image to fix this. - If the image lacks a color table, we create a default color table. - If the image is truncated, then the rest of the image is filled with the fill color. In all four cases, if images.gif.suppressDecoderWarnings is set to false, then a warning message is printed via SkDebugf. In the event of another kind of error, SkGIFImageDecoder::onDecode() will still return false. But with this change, if images.gif.suppressDecoderWarnings is set to false, a description of the error is printed via SkDebugf. Also, added a new unit test GifTest, which tests the deconing of both good GIf files and corrupted files that should now work with this change. This unit test is disabled on Win32, iOS, and Mac.

| | | | | | | | | | | | | | | | | | | | Only affects factories, static functions that will use the factories, and subset decoding, which all require rewinding. The decoders themselves continue to take an SkStream. This is merely documentation stating which functions will possibly rewind the passed in SkStream. This is part of the general change to coordinate SkStreams with Android's streams, which don't necessarily support rewinding in all cases. Update callers to use SkStreamRewindable.

In bench refactoring, I'm trying to register a function pointer of type T(*)(), which can't be done as is (passing P=void doesn't work).

| | | | | | | | | | | | | | | Now that Android is using an SkBitmap::Allocator to reuse bitmap memory, remove the unnecessary code to handle bitmap reuse inside the decoders themselves. Leaves in the code for bitmap reuse in decodeSubset, which still may reuse bitmaps, and cropBitmap, which is called by decodeSubset.
