* Fix filter primitive bounds computations.Gravatar senorblanco2015-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make each filter responsible for expanding its destination bounds. Previously, we were using a union of all intermediate bounds sizes via join() calls in many image filters' computeFastBounds(), due to the fact that those filters could only produce bitmaps the same size as their inputs. Now, we compute optimal bounds for each filter as follows: 1) Pass the (unmodified) clip bounds to the root node of the DAG in the first recursive call to onFilterImage() as the Context's fClipBounds. 2) Reverse-map the clip: when recursing up the DAG in filterInput[GPU](), apply filter-specific expansion to the clip by calling calling onFilterNodeBounds(... kReverse). This allows upstream nodes to have a clip that respects the current node's requirements. This is done via helper function mapContext(). 3) Forward-map the source bitmap: just prior to applying the crop rect in applyCropRect(), we determine the filter's preferred bounds by mapping the source bitmap bounds forwards via onFilterNodeBounds(..., kForward). NOTE: GMs affected by this change: fast_slow_blurimagefilter: fast and slow paths now produce the same result spritebitmap: drawSprite() and drawBitmap() paths now produce the same result filterfastbounds: fast bounds are optimized; all drop-shadow results now appear apply-filter: snug and not-snug cases give same results dropshadowimagefilter: drawSprite() results now show shadows draw-with-filter: no artifacts on erode edges; blur edges no longer clipped displacement, imagefiltersbase, imagefiltersclipped, imagefilterscropexpand, imagefiltersscaled, matriximagefilter, resizeimagefilter, localmatriximagefilter, testimagefilters: fixed incorrect clipping imagefilterstransformed, morphology: no artifacts on erode edges BUG=skia:1062,skia:3194,skia:3939,skia:4337,skia:4526 Review URL: https://codereview.chromium.org/1308703007

| | | | | | | | | | | | (This is essentially a revert of https://codereview.chromium.org/503833002/.) This was necessary back when SkPaint was flattened even for in-process use. Now that we only flatten SkPaint for cross-process use, there's no need to serialize UniqueIDs. Note: SkDropShadowImageFilter is being constructed with a croprect and UniqueID (of 0) in Blink. I've made the uniqueID param default to 0 temporarily, until this rolls in and Blink can be changed.

* Reimplement deserialization of SkImageFilter's uniqueID.Gravatar senorblanco2014-08-26
| | | | | | | | | | | | | | | | | | | | | | | 9fa60d ("Simplify flattening to just write enough ... ") simplified just a tad too much. In particular, it disabled deserialization of SkImageFilter's uniqueID, which in turn caused the failure of SkImageFilter's cache, which caused a large regression in Chrome's SVG filter performance. The medium-term fix is to switch to the new SkRecordDraw SkPicture backend, which will make the unique IDs unnecessary. This change is an "in case of emergecy" CL, in the event that there are problems switching on the new backend in Chrome. For that reason, it's minimalist: only the filters used by Chrome are modified, and whitespace changes are kept to a minimum. In this way, it should be easy to revert once the new backend goes in.

We want to *not* rely on private constructors, and not rely on calling through the inheritance hierarchy for either flattening or unflattening(CreateProc). Refactoring pattern: 1. guard the existing constructor(readbuffer) with the legacy build-flag 2. If you are a instancable subclass, implement CreateProc(readbuffer) to create a new instances from the buffer params (or return NULL). If you're a shader subclass 1. You must read/write the local matrix if your class accepts that in its factory/constructor, else ignore it.

* Factory methods for heap-allocated SkImageFilter objects.Gravatar commit-bot@chromium.org2014-03-10
| | | | | | | | | | | | | | | | | | This is part of an effort to ensure that all SkPaint effects can only be allocated on the heap. This patch makes the constructors of SkImageFilter and its subclasses non-public and instead provides factory methods for creating these objects on the heap.

* Implement correct clipping for image filters.Gravatar senorblanco@chromium.org2014-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | Image filters in Skia currently clip the size of the the offscreen bitmap used for filtering to the device clip bounds. This means that any pixel-moving filter (e.g., blur) has edge artifacts at the clip boundaries. This is problematic for tiling, where a single SkPicture is played back with a clip set to the tile boundaries. By implementing the onFilterBounds() traversal, and using it in saveLayer() when a filter is present, we can clip the layer to the expanded clip rect. Note that this requires that the traversal be performed in reverse as compared to computeFastBounds(). (It's also done in device space, unlike computeFastBounds()). New test imagefiltersclipped tests pixel-moving filters when clipped by various clip rects. New test imageblurtiled tests tiled (compositor-style) rendering of blurred text. There should be no artifacts at the tile boundaries.
