* store SkAlphaType inside SkBitmap, on road to support unpremulGravatar reed@google.com2013-10-21
| | | | | | | | | BUG= R=bsalomon@google.com, scroggo@google.com Review URL: https://codereview.chromium.org/25275004 git-svn-id: http://skia.googlecode.com/svn/trunk@11877 2bbb7eff-a529-9590-31e7-b0007b416f81
* 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.

* Change SkImageDecoders to take an SkStreamRewindable.Gravatar scroggo@google.com2013-09-25
| | | | | | | | | | | | | | | | | | | | 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.

* Rewrite SkTRegistry to take any trivially-copyable type.Gravatar mtklein@google.com2013-09-04
| | | | | | | | | | | | | | Obviously these are all currently function pointers of type T(*)(P) for various T and P. 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). This also lets us register things like primitives, which is conceivable useful.

| | | | | | | | | | | | | | Only call getLength() if hasLength() returned true. Otherwise, copy the stream into an SkDynamicMemoryWStream and copy it into alloc'ed space.

* Remove bitmap reuse from SkImageDecoder.Gravatar scroggo@google.com2013-07-09
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | skimage_main.cpp: More changes in the interest of testing our decoders. force_all_opaque before writing PNG files. Test reencoding the image to its original type (if possible), and then test redecoding it (to make sure the encoding was successful). Add an option to turn off this behavior. Merge decodeFileAndWrite with decodeFile. SkImageDecoder: Add kUnknown_Type to SkImageEncoder::Types. Add a static function to get the Format of an SkStream. In getFormatName(), remove an incorrect assert. When calling the flavor of DecodeStream that returns the Format, check the stream if the decoder returns kUnknown_Format.
