* Image filters: optimize crop rect application.Gravatar senorblanco2016-04-01
| | | | | | | | | | | | | | | | | | | If a filter does not affect transparent black, there's no reason to allow the crop rect to expand beyond the optimal size determined by onFilterNodeBounds(). So don't enlarge the bounds unless the filter affects transparent black. In order to determine which filters affect transparent black, I've pulled the inverse of the canComputeFastBounds() logic into a non-recursive, affectsTransparentBlack() virtual, and left canComputeFastBounds() as a non-virtual, recursive function that calls it.

| | | | | | | | | | | | | | | | | traversal which respects the CropRect. This is useful when you want the device-space bounds of a primitive after filtering. (This may also eventually subsume computeFastBounds()). This CL generalizes filterBounds() and onFilterBounds() to take a mapping direction. It also makes filterBounds() responsible for calling onFilterNodeBounds() and applying the crop rect, simplifying onFilterBounds().

* Fix SkMergeImageFilter crop rect computation.Gravatar senorblanco2015-11-25
| | | | | | | | | | | | | | | | | | | | | The crop rect should be applied to the union of the input bounds, not to the src input's bounds. These are often the same, since the saveLayer offscreen size is computed as the union of all the required bounds, but is not correct if the input primitive is not used (e.g., if all inputs are connected to SkImageSources). But this will change as we move to more accurate intermediate bounds computations (getting rid of the join() hacks as described in skbug.com/3194). Since we can't know this without actually processing the inputs, split SkMergeImageFilter processing into: - filter all inputs - applyCropRect to the union'ed bounds - allocate the destination - do the merge BUG=3194 Review URL: https://codereview.chromium.org/1475793002

| | | | | | | | | | | | (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.

* Clean up SkImageFilter constructors.Gravatar senorblanco2014-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now that all creation of SkImageFilters goes through factory Create() methods, there's no real reason for the convenience constructors. Some SkImageFilter subclasses which actually have zero DAG-able inputs were passing NULL to the superclass constructor. This actually means 1 input, with a NULL value, not zero inputs. This becomes more relevant for the upcoming cache infrastructure, where this indicates that the filter will use its src input, where in fact some of these filters do not (they are image generators only). Limiting SkImageFilter to a single constructor resolves this ambiguity. Along the way, I removed all of the default parameters to the constructors, since the Create methods always call them with the full argument list.

* Implement support for expanding crop rects in image filtersGravatar senorblanco@chromium.org2014-03-14

Until now, crop rects in Skia have only been able to reduce the size of the destination bounds, but not expand them. SVG semantics require the latter as well. The heart of the change is in applyCropRect(), which now assigns each edge, instead of doing an intersection with the crop rect. In order to support this (and still work well with tiled drawing) we need to clip the resulting crop rect to the clipping region of the filters. This uses the Context struct previously landed from https://codereview.chromium.org/189913021/. Many of the pixel loops are not yet ready to handle a destination rect larger than the source rect. So we provide a convenience version of applyCropRect() which creates an offscreen and pads it out with transparent black. Once the pixel loops and shaders have been fixed to support larger destination bounds, they should be switched back to the non-drawing version of applyCropRect().

* 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.

* Make SkImageFilter crop rects relative to the primitive origin, instead of ↵Gravatar senorblanco@chromium.org2014-01-03
| | | | | | | | | | | | | | | | | | relative to their parent's crop rect. This is required by SVG semantics, and is more sane anyway. To do this, this patch changes the "offset/loc" parameter in filterImage() / onFilterImage() from an inout-param to an out-param only, so that the calling filter can know how much the input filter wants its result offset (and doesn't include the original primitive position). This offset can then be applied to the current filter's crop rect. (I've renamed the parameter "offset" in all cases to make this clear.) This makes the call sites in SkCanvas/SkGpuDevice responsible for applying the resulting offset to the primitive's position, which is actually a fairly small change. This change also fixes SkTileImageFilter and SkOffsetImageFilter to correctly handle an input offset, which they weren't before. This required modifying the GM's, since they assumed the broken behaviour. NOTE: this will require rebaselining the imagefiltersgraph test, since it has a new test case. NOTE: this will "break" the Blink layout tests css3/filters/effect-reference-subregion-chained-hw.html and css3/filters/effect-reference-subregion-hw.html, but it actually makes them give correct results. It should be suppressed on the skia roll, and I'll rebaseline it.

| | | | | | | | | | | | | | | | | | | In some cases, the allocated array into which the data will be read is using getArrayCount() to allocate itself, which should be safe, but some cases use fixed length arrays or compute the array size before reading, which could overflow if the stream is compromised. To prevent that from happening, I added a check that will verify that the number of bytes to read will not exceed the capacity of the input buffer argument passed to all the read...Array() functions. I chose to use the byte array for this initial version, so that "size" represents the same value across all read...Array() functions, but I could also use the element count, if it is preferred. Note : readPointArray and writePointArray are unused, so I could also remove them BUG= R=reed@google.com, mtklein@google.com, senorblanco@chromium.org Author: sugoi@chromium.org Review URL: https://codereview.chromium.org/37803002 git-svn-id: http://skia.googlecode.com/svn/trunk@12058 2bbb7eff-a529-9590-31e7-b0007b416f81
