* Decouple the SkFlattenable from SkReader32/SkWriter32.Gravatar djsollen@google.com2012-04-12
| | | | | | | | | | The current impl for SkFlattenable read/write buffers is that they extend from SkReader32 and SkWriter32, but that dependency must be abstract if we are to add any other serialization format.

* Cleanup code related to SkFlattenable::flatten()Gravatar djsollen@google.com2012-03-29
| | | | | | | | | | | | | | | | | The following changes were made by this CL: 1. Make flatten() a protected method as callers should use SkFlattenableWriteBuffer to flatten an object 2. Make flatten a const method (including subclasses) 3. Mark subclass implementation of flatten with SK_OVERRIDE 4. Ensure overridden flatten impls call their parent 5. Remove no-op implementations of flatten from subclasses Additionally, if necessary the unflattening constructor was also moved to the protected section of the subclasses header if it was not already there. git-svn-id: http://skia.googlecode.com/svn/trunk@3540 2bbb7eff-a529-9590-31e7-b0007b416f81

* fix bug where we wrote uninitialized data to the flatten stream for shaders.Gravatar reed@google.com2011-05-10
| | | | | | | | | | | | | | | | | | | Both shader and gradient_shader write matrices to the flatten stream. However, they were just calling write(&matrix, sizeof(SkMatrix)) and the matrix can contain lazily-computed function ptrs as part of its internal cache. Thus two matrices that are logically the same may write different bytes. This is a problem because picture relies on flattening objects and then using the flatten stream as a key into its cache. This matrix-write bug effectively kills the effectiveness of the cache for shaders. The fix is to write proper read/write functions for matrix (and region btw). These call through to the existing low-level flatten routines (which just write into a memory ptr). git-svn-id: http://skia.googlecode.com/svn/trunk@1290 2bbb7eff-a529-9590-31e7-b0007b416f81

* expand SkShader's flag kConstInY to 16 and 32 variants, allowing a shaderGravatar reed@android.com2009-08-27
| | | | | | | | | | | | (like gradients) to support predithering. If they do, then they would suppress kConstInY16, since they no longer are const. The blitters now check for each flag separately, so we don't have to give up const-in-Y in the 32bit case, since in that mode we don't care about dithering. git-svn-id: http://skia.googlecode.com/svn/trunk@339 2bbb7eff-a529-9590-31e7-b0007b416f81
* add shader flag kConstInY_FlagGravatar reed@android.com2009-06-12
| | | | | | | | | | | this signals blitters that the shader will return the same results for a given x value, independent of y. Useful inside blitRect(), where it can cache the first call to shadeSpan() and reuse it on all subsequent scans. Works with (non-rotated) linear-gradients, and Nx1 bitmaps. git-svn-id: http://skia.googlecode.com/svn/trunk@214 2bbb7eff-a529-9590-31e7-b0007b416f81
