* Support decoding opaque to *premulGravatar scroggo2016-02-03
| | | | | | | | | | | | | | | | | | | | | | If a client requests unpremul or premul from an opaque SkCodec, support it. The opaque image can be treated as any of them, though it will be less efficient to draw than if the client had used opaque. Change the filling code (i.e. for incomplete images) to base its color on the source alpha type. Prior to adding the support to decode opaque to any, it was fine to use either source or dest (which would have yielded the same result). If the client requests non-opaque, we do not want this to switch the fill value from black to transparent. This also allows simplifying the signatures for getFillValue and onGetFillValue. In CodexTest, expect the same result when decoding opaque to *premul, and compare to the opaque version.

* Add reallyHasAlpha() to SkAndroidCodecGravatar msarett2015-12-10
| | | | | | | | | This also modified the default implementation of onReallyHasAlpha() in SkCodec. BUG=skia: Review URL: https://codereview.chromium.org/1518743002
* Switch SkAutoMalloc to SkAutoTMalloc to avoid castGravatar scroggo2015-12-10
| | | | | | | | | | | | Make SkAutoTMalloc's interface look more like SkAutoMalloc: - add free(), which does what you expect - make reset() return a pointer fPtr No public API changes (SkAutoTMalloc is in include/private) BUG=skia:2148 Review URL: https://codereview.chromium.org/1516833003
* Make SkAndroidCodec support gifGravatar msarett2015-11-17
| | | | | | | | | Involves a few bug fixes in SkCodec_libgif and a bit more complexity in SkSwizzler. BUG=skia:4405 Review URL: https://codereview.chromium.org/1445313002

* Make AndroidOptions constGravatar scroggo2015-11-04
| | | | | | | | | Make the struct passed to SkAndroidCodec::getAndroidPixels const. This matches SkCodec, and makes sense, since it is not used as an output. Brought up in crrev.com/1417583009 Review URL: https://codereview.chromium.org/1411693005
* Combine native sampling with samplingGravatar scroggo2015-11-03
| | | | | | | | | | | | In SkSampledCodec, allow the native codec to do its scaling first, then sample on top of that. Since the only codec which can do native scaling is JPEG, and we know what it can do, hard-code for JPEG. Check to see if the sampleSize is something JPEG supports, or a multiple of something it supports. If so, use JPEG directly or combine them.
