* Replace a lot of 'static const' with 'constexpr' or 'const'.Gravatar mtklein2016-09-01
| | | | | | | | | | | | | | | | | | | | | | | 'static const' means, there must be at most one of these, and initialize it at compile time if possible or runtime if necessary. This leads to unexpected code execution, and TSAN* will complain about races on the guard variables. Generally 'constexpr' or 'const' are better choices. Neither can cause races: they're either intialized at compile time (constexpr) or intialized each time independently (const). This CL prefers constexpr where possible, and uses const where not. It even prefers constexpr over const where they don't make a difference... I want to have lots of examples of constexpr for people to see and mimic. The scoped-to-class static has nothing to do with any of this, and is not changed. * Not yet on the bots, which use an older TSAN.

* Update feSpotLight to match specGravatar ericrk2015-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change updates feSpotLight to match the spec via two changes: 1) specularExponent is ignored if the spotlight has no coneAngle (GPU bug only). This change updates the GPU path so that it matches the CPU path and the spec in this regard. 2) specularExponent is clamped to the 1-128 range. The spec does not specify a clamp for the specularExponent attribute of feSpotLight. Note that the spec *does* specify this clamp for the specularExponent attribute of feSpecularLighting. It looks like we incorrectly applied this to both specularExponent attributes. This change (along with a parallel change in Blink) allows us to pass the SVG filter effects conformance test here: http://www.w3.org/Graphics/SVG/Test/20110816/harness/htmlObject/filters-light-01-f.html Additionally, this brings our behavior in line with Safari and Edge’s behavior on this filter. Two new cases were added to gm/lighting.cpp to catch these issues: - The existing spotlight case exercised the path where our specular exponent was between 1-128 and had a limiting cone angle. - The first new spotlight case exercises the path where our specular exponent is between 1-128 and we do not have a limiting cone angle. - The second new spotlight case exercises the path where the specular exponent is not within the 1-128 range, to ensure that we don’t incorrectly clip to this range.

* Implement approx-match support in image filter saveLayer() offscreen.Gravatar senorblanco2015-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the GPU-side image filter implementation creates exact-match textures for the offscreen backing stores for saveLayer(). This is because several filters have GPU implementations which depend on the texture coordinates being 0..1. The fix is three-fold: 1) Store the actual requested size in the SkGpuDevice, so that when wrapping it in an SkBitmap for passing to filterImage(), we can give it the original size. 2) Fix the filters (SkMagnifierImageFilter, SkLightingImageFilter, SkMatrixConvolutionImageFilter, SkMatrixImageFilter) whose GPU implementation depends on 0..1 texture coordinates. 3) Remove the exception for GPU-side image filters in SkCanvas::internalSaveLayer(). For the lighting filters, there were two bugs which were cancelling each other out: the sobel filter matrix was being computed upside down, but then we'd negate the resulting normal. This worked fine in the exact-match case, but in the approx-match case we'd sample garbage along the edge pixels. Also, we never implemented the edge pixels according to spec in the GPU case. It requires a different fragment shader for each edge of the nine-patch, which meant we couldn't use asFragmentProcessor(), and had to implement the drawing via a filterImageGPU() override. In order to avoid polluting the public API, I inserted a new base class, SkLightingImageFilterInternal above Sk[Diffuse|Specular]LightingImageFilter to handle the implementation. For the SkMatrixConvolutionImageFilter, it seems the GLSL clamp() function occasionally returns values outside the clamped range, resulting in access of garbage texels even in GL_NEAREST. The fix here is to clamp to a rect inset by half a texel. There was also a bug in the unpremultiply step when fConvolveAlpha is false. For SkMatrixImageFilter, the fix was to make the generic draw path be more careful about when to use texture domain. If the bitmap already has a texture, use texture domain if the srcRect is smaller than the entire texture (not the entire bitmap). N.B.: this change will cause some minor pixel diffs in the GPU results of the following GMs (and possibly more): matriximagefilter, matrixconvolution, imagefiltersscaled, lighting, imagemagnifier, filterfastbounds, complexclip_aa_Layer_invert, complexclip_aa_layer, complexclip_bw_layer_invert, complexclip_bw_layer.

* Add standard fonts to all GMs.Gravatar Cary Clark2014-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow GM results to be compared across machines and platforms by standardizing the fonts used by all tests. This adds runtime flags to DM to use either the system font context (the default), the fonts in the resources directory ( --resourceFonts ) or a set of canonical paths generated from the fonts ( --portableFonts ). This CL should leave the current DM results unchanged by default. If the portable font data or resource font is missing when DM is run, it falls back to using the system font context. The create_test_font tool generates the paths and metrics read by DM with the --portableFonts flag set, and generates the font substitution tables read by DM with the --resourceFonts flag set. If DM is run in SkDebug mode with the --reportUsedChars flag set, it generates the corresponding data compiled into the create_test_font tool. All GM tests set their typeface information by calling either sk_tool_utils::set_portable_typeface or sk_tool_utils::portable_typeface . (The former takes the paint, the latter returns a SkTypeface.) These calls can be removed in the future when the Font Manager can be superceded. BUG=skia:2687 R=mtklein@google.com Review URL: https://codereview.chromium.org/407183003

* In image filters, apply the CTM and offset to the crop rect. This is ↵Gravatar senorblanco@chromium.org2013-08-27
| | | | | | | | | | | | | | necessary to compensate for both clipping applied by the compositor (communicated via the CTM) and for cropping applied in upstream image filters (communicated via the offset). This requires a few ugly conversions, since the crop rect is an SkIRect, and the ctm is an SkMatrix. I also had to offset the matrix passed to filter evaluation by drawSprite() and internalDrawBitmap() by the primitive position. This is the same offset that is applied when drawing the primitive, to compensate for the internal saveLayer(). Also apply the total matrix to the filter params in asNewEffect(), so that (for example) lighting params are offset by both the compositor clipping and upstream crop rects.

* Implement crop rect for lighting image filters. Changes for the CPU path ↵Gravatar senorblanco@chromium.org2013-07-26
| | | | | | | | | | | | | | were fairly straightforward: use the bounds rectangle when traversing the pixels, not the source rectangle. For the GPU path, this required modifying the signature of SkImageFilter::asNewEffect() to receive the bounds offset, so that the lighting filters could offset the light position by the offset. It also required modifying the base-class implementation of SkImageFilter::filterImageGPU() (which implements single-pass filters) to intersect against the bounds rect, to pass its offset to asNewEffect(), and to modify the caller's offset (so it's drawn in the correct place). Note: this will require rebaselining the lighting GM. Six new test cases were added, to accommodate a cropped version of each lighting filter.

the caller instantiates a light (distant, point or spot), and an SkDiffuseLightingFilter or SkSpecularLightingImageFilter with that light. A Sobel edge detection filter is applied to the alpha of the incoming bitmap, and the result is used as a height map for lighting calculations.
