◆ onFilter()

bool DebugPaintFilterCanvas::onFilter ( SkPaint &  paint) const
inlineoverrideprotectedvirtual

Called with the paint that will be used to draw the specified type. The implementation may modify the paint as they wish.

The result bool is used to determine whether the draw op is to be executed (true) or skipped (false).

Note: The base implementation calls onFilter() for top-level/explicit paints only. To also filter encapsulated paints (e.g. SkPicture, SkTextBlob), clients may need to override the relevant methods (i.e. drawPicture, drawTextBlob).

Implements SkPaintFilterCanvas.
