◆ SkPaintFilterCanvas()

SkPaintFilterCanvas::SkPaintFilterCanvas ( SkCanvas * canvas )

The new SkPaintFilterCanvas is configured for forwarding to the specified canvas. Also copies the target canvas matrix and clip bounds.

◆ getBaseLayerSize()

SkISize SkPaintFilterCanvas::getBaseLayerSize ( ) const

inlineoverridevirtual

Gets the size of the base or root layer in global canvas coordinates. The origin of the base layer is always (0,0). The area available for drawing may be smaller (due to clipping or saveLayer).

Returns: integral width and height of base layer

example: https://fiddle.skia.org/c/@Canvas_getBaseLayerSize

◆ onFilter()

virtual bool SkPaintFilterCanvas::onFilter ( SkPaint & paint ) const

protectedpure virtual

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).

Implemented in DebugPaintFilterCanvas, and OveridePaintFilterCanvas.
