* Image decoder fixes (mostly) around A8.Gravatar scroggo@google.com2013-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Opaquness: When decoding Gray to A8 in libpng, set reallyHasAlpha to true and add a comment why we do not check for the real answer. Add comments in jpeg decoder explaining why A8 is not opaque. Fix a bug where an A8 subset is considered to be opaque. Other fixes: In SkJPEGImageDecoder, only allocate as much memory as needed for each source row, based on the input config. Also pull out common code into a static function. When performing the check for requiring unpremultiplied colors, allow A8 to succeed, since that setting should have no effect on A8. Add the check for requiring unpremultiplied colors to subset decoding. Fix a bug where attempting to sample gray to A8 does not sample.

* Make image decoding more fault resistant, less verbose.Gravatar halcanary@google.com2013-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change address what happens when a jpeg is partially downloaded before failing. Many browsers will render it anyway: we want Skia to do the same. The JpegTest takes a perfectly cromulent jpeg file and only passes into the ImageDecoder the first half of the image. We then verify that the image decoder returns a valid bitmap of the correct dimensions. We also fixed some png library errors, including issue 1691. Also, suppressed the majority of warnings from using libpng and libjpeg. By default, most warnings are *not* suppressed in debug mode. If you have a debug binary and wish to suppress warnings, set the following environment variables to true skia_images_png_suppressDecoderWarnings skia_images_jpeg_suppressDecoderWarnings or from within a program that links to Skia: #if defined(SK_DEBUG) #include "SkRTConf.h" SK_CONF_SET("images.jpeg.suppressDecoderWarnings", true); SK_CONF_SET("images.png.suppressDecoderWarnings", true); #endif I tested this, before (control) and after these changes (test), on 364,295 skps from the cluster telemetry. - number of errors+warnings in control = 2804 - number of errors+warnings fixed = 2283 - number of PNG verbosity fixed = 2152 - number of PNG error fixed = 4 - number of PNG segfault fixed = 3 - number of PNG errors changed to warnings = 62 - number of JPG verbosity fixed = 26 - number of JPG error fixed = 91 Not all errors and warning have been fixed. These numbers were generated using the find_bad_images_in_skps.py program. This program may be useful going forward for testing image-decoding libraries on skp files from the cluster telemetry. find_bad_images_in_skps.py depends on the test_image_decoder program, which simply executes the SkImageDecoder::DecodeFile function and uses its exit status to report success or failure.

* Fixes for decoding to A8.Gravatar commit-bot@chromium.org2013-10-03
| | | | | | | | | | | | | | | | | | | | | | | | src/images/SkImageDecoder_libpng.cpp: A8 images are not opaque, so do not set the opaque flag. This fixes a bug where copyTo does not work as expected (when copying an A8 decoded image to ARGB_8888), leading to a bitmap hash that does not represent the image correctly (in skimage). tools/skimage_main.cpp: In write_bitmap, which is creating the image for visual comparison, copy A8 to 8888, since A8 cannot be encoded. In the section that tests reencoding, do not test reencoding A8, which is known to not work.

* Add an option on SkImageDecoder to skip writing 0s.Gravatar scroggo@google.com2013-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only implemented for PNG. Add a getter and setter, and sets the default to false in the constructor. Also copies the setting in copyFieldsToOther. Fix an indpendent bug where fDitherImage was not being copied in copyFieldsToOther. In SkScaledBitmapSampler::begin, consolidate the settings passed in by passing a const reference to the decoder. The decoder can be referenced for its settings of dither, unpremultiplied, and now skipping writing zeroes. Update callers to use the new API. In png decoder, rather than passing around a pointer to an initial read of getDitherImage, and potentially changing it, look at the field on the decoder itself, and modify it directly. This is a change in behavior - now if that same decoder is used to decode a different image, the dither setting has changed. I think this is okay because A) the typical use case is to use a new decoder for each decode, B) we do not make any promises that a decode does not change the decoder and C) it makes the code in SkScaledBitmapSampler much cleaner. In SkScaledBitmapScampler, add new row procs for skipping zeroes. Now that choosing the row proc has five dimensions (src config, dst config, dither, skip writing zeroes, unpremultiplied), use a new method: each src/dst combination has a function for choosing the right proc depending on the decoder. SkScaledBitmapScampler::RowProc is now public for convenience. Remove Sample_Gray_D8888_Unpremul, which is effectively no different from Sample_Gray_D8888. In cases where unpremultiplied was trivial, such as 565 and when sampling from gray, decoding may now succeed. Add a benchmark (currently disabled) for comparing the speed of skipping writing zeroes versus not skipping. For this particular image, which is mostly transparent pixels, normal decoding took about 3.6 milliseconds, while skipping zeroes in the decode took only about 2.5 milliseconds (this is on a Nexus 4). Presumably it would be slower on an image with a small amount of transparency, but there will be no slowdown for an image which reports that it has no transparency. In SkImageRef_ashmem, always skip writing zeroes, since ashmem memory is guaranteed to be initialized to 0. Add a flag to skip writing zeroes in skimage. Add a regression test for choosing the rowproc to ensure I did not change any behavior accidentally.

| | | | | | | | | | | | | | | | | | | | 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.

Write out a PNG of the region as well as a bitmap obtained with extractSubset for comparison. Rename decodeRegion to decodeSubset, so it will not be confused with SkRegion. (Leave a function called decodeRegion which calls decodeSubset.) Clean up some comments. Use png_set_interlaced_pass instead of modifying pass directly. Make some changes to region decoding to fix problems I discovered during testing: Only call getAddr within a valid range. Check for a NULL fInputStream. Return a boolean for whether cropBitmap succeeded. In cropBitmap, do not attempt to draw to a bitmap to an Index8 bitmap, which crashes. Use extractSubset instead. Remove an assert.

Note: there is one png_structp direct field acces left in SkPNGImageDecoder::onDecodeRegion() for which libpng does not provide a wrapper method (png_ptr->pass = 0). That should be OK for now as the code is only enabled when SK_BUILD_FOR_ANDROID is set, and the Android libpng version is striclty controlled.
