Constructor Details

PaintFilterCanvas

public PaintFilterCanvas(@RawPtr
 @RawPtr @NonNull Canvas canvas)

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

Method Details

onFilter

public abstract boolean onFilter(Paint paint)

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. Picture, TextBlob), clients may need to override the relevant methods (i.e. drawPicture, drawTextBlob).

getBaseLayerWidth

public int getBaseLayerWidth()

Description copied from class: Canvas

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).

Overrides:

getBaseLayerWidth in class Canvas

Returns:

integral width of base layer

getBaseLayerHeight

public int getBaseLayerHeight()

Description copied from class: Canvas

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).

Overrides:

getBaseLayerHeight in class Canvas

Returns:

integral height of base layer

getCommandContext

public @Nullable Context getCommandContext()

Description copied from class: Canvas

Returns GPU context of the GPU surface associated with Canvas.

Overrides:

getCommandContext in class Canvas

Returns:

GPU context, if available; null otherwise
