Line2DPathEffect fill the closed path badly.

[庄小龙]

Hello, I run into one issue when use Line2DPathEffect. Can someone help here? Thanks very much.

sample code:

https://fiddle.skia.org/c/8b2d908975bc9c2d02ef9bbd70455a07

The result:

The filled lines don't end on the border. They go beyond or don't get to the border.

And also SkPath2DPathEffect has the same problem.

It's not a great solution, but if you also clip to the path, none of the tiled paths will extend outside the bounds: https://fiddle.skia.org/c/a52b91041898a6c62df27eb90a7be222

There is still the issue that the left-edge is jagged, because of how the tiling starts.

Thanks for your reply.

About the jag at the left edge, the solution I can find out is to use a path with bigger region to draw the Line2DPathEffect. But it may be time costly.

Any other suggestions for the issue?
