* Remove uniqueID from all filter serialization.Gravatar senorblanco2015-03-18
| | | | | | | | | | | | (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. (Blink can't be changed first, since unlike the other filters, there's no constructor that takes a cropRect but not a uniqueID.) BUG=skia: Review URL: https://codereview.chromium.org/1019493002

* Allow negative values in SkBlurImageFilter sigma.Gravatar senorblanco2014-09-09
| | | | | | | | | | | | | | | | | | | | | There are two ways negative sigma values may occur: in the original filter parameters, or after multiplication by a negative scaling CTM. The former case is invalid according to the spec, so we continue to check for it at validation time. In the latter case, we should interpret it as a horizontal flip in the kernel pixel access, and simply take the absolute value (since the filter kernel is symmetric). Also refactor all this logic into a single place for the CPU, GPU and onFilterBounds() paths.

* 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.

| | | | | | | | | | | | | | | | | | factory/public-constructor for the class. 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 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.

* Apply the CTM to filter parameters for SkBlurImageFilter, ↵Gravatar senorblanco@chromium.org2014-01-20
| | | | | | | | | | | | SkDropShadowImageFilter, SkDisplacementMapEffect and SkMorphologyImageFilter. I had resisted this (and may later put in an assert that the CTM contains no rotation, skew or perspective), but it just makes the filters play better with Skia generally. This revealed that the displacement map was not handling clipping or upstream cropping at all well (the color would "swim" through the displacement at the edge of the clip rect). Fixed by passing through the correct offsets to the bitmap accesses in both raster and GPU paths. Same for morphology.

* 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.

* Fixed bad bitmap size crashesGravatar commit-bot@chromium.org2013-12-04
| | | | | | | | | | | | | | | There were 2 issues : 1 ) If the size of an SkBitmap's underlying SkPixelRef's alocated memory is too small to fit the bitmap, then the deserialization will now check this and set an error appropriately. 2 ) If a device fails to allocate its pixels, the device will be deleted and NULL will be returned to avoid attempting to draw on a bad device.
