* Make flattenables no longer depend on global static initializers.Gravatar scroggo@google.com2012-09-21
| | | | | | | | | | | | | | | | | Instead, force all builds to call InitializeFlattenables. Remove the make_debugger script, which was created to force rebuilding without global static initializers so that all flattenables would be linked. It is no longer necessary since all flattenables will be linked thanks to InitializeFlattenables, which now can (and must) be called when global static initializers are turned on.

* Implements a new class, SkSingleInputImageFilter, to handle DAG connectivityGravatar senorblanco@chromium.org2012-08-20
| | | | | | | | | | | | | | | | | | | | | for filters with a single image input. This provides functionality to store, flatten and unflatten a single SkImageFilter input, as well as to recursively evaluate it on the CPU or GPU. The following classes were re-parented to implement DAG connectivity: SkBlurImageFilter, SkDilateImageFilter, SkErodeImageFilter, SkColorFilterImageFilter. The constructors for each have been appended with a new parameter, representing the input filter (default NULL). This change also implements an arbitrary SkBitmap input source for filtering, SkBitmapSource. NOTE: This CL will require gyp file changes when rolling past this revision.

* Update SkFlattenable buffers to be more modular.Gravatar djsollen@google.com2012-08-07
| | | | | | | | | | | | | | | | | This CL is an effort to stage the conversion to named parameters for all SkFlattenable commands. This particular stage only does the following two things... 1. Move flattenable buffers from SkFlattenable.h into their own header. 2. Update and Add new read write methods for better clarity and convenience.

* 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

* This change makes SkImageFilter and SkBlurImageFilter flattenable/unflattenable.Gravatar senorblanco@chromium.org2011-11-16

* Implement Gaussian blurs for images. The caller creates an anGravatar senorblanco@chromium.org2011-11-09
SkBlurImageFilter, sets it on an SkPaint, passes that paint to saveLayer(), draws the primitives which are to be blurred, then calls restore(), which applies the blur. The blurs have separate sizes in the horizontal and vertical direction. This feature is GPU-only for now. NB: Due to the clipping change, there are slight pixel differences on the blurs_gpu and shadows_gpu tests, so those will require rebaselining on all platforms, as will some of the WebKit layout tests (TBD).
