* fixing onSkipScanlines png errorGravatar emmaleer2015-05-27
| | | | | | | There was a bug in onSkipScanlines where NULL was being passed instead of the SrcRow to png_read_rows. This caused SkipScanlines to appear to be skipping, as fCurrScanline was updated and SkipScanlines returned success, however png_read_rows was not actually reading anything, and no lines were skipped.

* Implementing filling for SkBmpCodecGravatar msarett2015-04-10
| | | | | | | | | | | | | | | The bmp codec currently returns kIncompleteInput when the stream is truncated, which we treat as a partial success. However, we neglect the fill the remaining pixels in the image, leaving these uninitialized. This CL addresses this problem by initializing the remaining pixels in the image to default values.

* ***Disables swizzles to 565.Gravatar msarett2015-04-09
| | | | | | | | | | | | | | | | | | | | | | | We may want to enable swizzles to 565 for images that are encoded in a format similar to 565, however, we do not want to take images that decode naturally to kN32 and then convert them to 565. ***Enable swizzles to kIndex_8. For images encoded in a color table format, we suggest that they be decoded to kIndex_8. When we decode, we only allow conversion to kIndex_8 if it matches the suggested color type (except wbmp which seems good as is). ***Modify dm to test images that decode to kIndex_8.

* Enable both static and dynamically linked libpngGravatar djsollen2015-04-03
| | | | | | | | | | | All platforms except android are configured to use the statically linked copy of libpng. Android uses the system provided dynamic copy for SkImageDecoder and the static copy for SkCodec. The exception being android framework builds that currently use the dynamic copy everywhere. This CL also enables NEON optimizations for libpng. Review URL: https://codereview.chromium.org/1058823002
* 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
* SkCodec::onGetScanlineDecoder must call rewind.Gravatar scroggo2015-04-01
| | | | | | | | | | | | | | | | | | | | This mirrors the behavior in onGetPixels, and allows the implementation to share code for handling calls to rewindIfNeeded. This also fixes a bug where getScanlineDecoder was calling rewindIfNeeded and treating the result as a bool. In SkPngCodec, factor out the code to call rewindIfNeeded, and call it in both onGetPixels and onGetScanlineDecoder. Update the test to include testing the scanline decoder. Rename "gen" to "codec" now that it must be an SkCodec. BUG=skia:3257 Depends on https://codereview.chromium.org/1048423003/ (DIFFERENT ISSUE). Review URL: https://codereview.chromium.org/1050893002

* Add scanline decoding to SkCodec.Gravatar scroggo2015-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an interface for decoding scanlines, and implement that interface in the PNG decoder. Use a separate method to determine whether an image that used a type with alpha was actually opaque. SkScanlineDecoder.h: New interface for decoding scanlines. SkCodec.h: Add getScanlineDecoder. Add a virtual function (with non-virtual caller) for determining whether the image truly had alpha. The client can call this to determine if the image was actually opaque if it reported having alpha. Remove code to sneakily change the passed in alpha type. SkCodec_libpng.*: Split up code onGetPixels into helper functions that can be shared with the scanline decoder. Implement scanline decoding. Implement onReallyHasAlpha. SkSwizzler.*: Add a new SrcConfig as a default, which is invalid. Add a function for setting fDstRow directly. Assert fDstRow is not NULL.
