8-bit alpha mask for clipping. More...

#include <tiny_skia/Mask.h>

Public Member Functions
std::vector< std::uint8_t >	release ()
	Releases the underlying byte buffer.
void	fillPath (const Path &path, FillRule fillRule, bool antiAlias, Transform transform)
	Draws a filled path onto the mask (white=255 where filled).
void	intersectPath (const Path &path, FillRule fillRule, bool antiAlias, Transform transform)
	Intersects (AND) a path with the current mask contents.
void	invert ()
	Inverts all mask values (255 - x).
void	clear ()
	Clears the mask to zero.

Static Public Member Functions
static std::optional< Mask >	fromSize (std::uint32_t width, std::uint32_t height)
	Creates a zero-filled mask. Returns nullopt for zero dimensions.
static std::optional< Mask >	fromVec (std::vector< std::uint8_t > data, IntSize size)
	Creates a mask from existing data. Returns nullopt if size mismatches.
static Mask	fromPixmap (const PixmapView &pixmap, MaskType maskType)
	Extracts a mask from a pixmap's alpha or luminance channel.

Detailed Description

Create with fromSize() (zero-filled), then draw paths with fillPath() or derive from a pixmap with fromPixmap(). Pass to Painter methods to clip drawing to the mask.
