* Use Color Processor for color bitmap text draws on gpu.Gravatar egdaniel2014-10-31
| | | | | | | | | | | | | | | | | | | This change is here since previously color bitmap text was rendered using a geometry processor in the coverage stage. The problem with this is that we cannot correctly do xfer modes with this method. So I now make color bitmap text draw using a color stage in the same was as a draw bitmap call. One issue that arrises from this fix is that we end up adding this final color processor after any previous color processors. Thus if we have a custom blend implemented as a color processor it will be before this text one and we won't blend correctly. This issue will get fixed once an xfer processor is fully implemented. I have hacked a test locally to show that if we can add the text color processor to the begining of the color stages we do blend correctly in all cases (so the xfer processor will be a fix).

* Draw more accurate thick-stroked Beziers (disabled)Gravatar caryclark2014-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Draw thick-stroked Beziers by computing the outset quadratic, measuring the error, and subdividing until the error is within a predetermined limit. To try this CL out, change src/core/SkStroke.h:18 to #define QUAD_STROKE_APPROXIMATION 1 or from the command line: CPPFLAGS="-D QUAD_STROKE_APPROXIMATION=1" ./gyp_skia Here's what's in this CL: bench/BezierBench.cpp : a microbench for examining where the time is going gm/beziers.cpp : random Beziers with various thicknesses gm/smallarc.cpp : a distillation of bug skia:2769 samplecode/SampleRotateCircles.cpp : controls added for error, limit, width src/core/SkStroke.cpp : the new stroke implementation (disabled) tests/StrokerTest.cpp : a stroke torture test that checks normal and extreme values The new stroke algorithm has a tweakable parameter: stroker.setError(1); (SkStrokeRec.cpp:112) The stroke error is the allowable gap between the midpoint of the stroke quadratic and the center Bezier. As the projection from the quadratic approaches the endpoints, the error is decreased proportionally so that it is always inside the quadratic curve. An overview of how this works: - For a given T range of a Bezier, compute the perpendiculars and find the points outset and inset for some radius. - Construct tangents for the quadratic stroke. - If the tangent don't intersect between them (may happen with cubics), subdivide. - If the quadratic stroke end points are close (again, may happen with cubics), draw a line between them. - Compute the quadratic formed by the intersecting tangents. - If the midpoint of the quadratic is close to the midpoint of the Bezier perpendicular, return the quadratic. - If the end of the stroke at the Bezier midpoint doesn't intersect the quad's bounds, subdivide. - Find where the Bezier midpoint ray intersects the quadratic. - If the intersection is too close to the quad's endpoints, subdivide. - If the error is large proportional to the intersection's distance to the quad's endpoints, subdivide.

* Strip old backend recording down to essentialsGravatar mtklein2014-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | Feature-wise, this removes: 1) BBH support; 2) peephole optimizations; 3) record-time text op specializations; 4) the guarantee that SkPaints are flattened. This deletes the optimizations GM, which only exists to test the peepholes of the old backend. SkRecord optimizations are unit tested, and if that ever fails we can think about adding another GM like this, but they're different enough we'd want to start from scratch anyway. We need to keep the code that plays back the specialized text ops around for a while for compatibility with existing .SKPs that have those ops recorded.

Each patch defines a method genMesh that produces the geometry to draw.

Later they call function like setColor or pointAt to set the values at a specific index, the SkMeshPatch object handles the indices based on the format and makes it transparent to the client.
