tiny_skia::Pixmap Class Reference

Owned RGBA pixel buffer. Always premultiplied alpha internally. More...

#include <tiny_skia/Pixmap.h>

Public Member Functions
PixmapView	view () const
	Immutable view.
MutablePixmapView	mutableView ()
	Mutable view — the primary drawing target.
std::span< const std::uint8_t >	data () const
	Raw byte data (premultiplied RGBA), const.
std::span< std::uint8_t >	data ()
	Raw byte data (premultiplied RGBA), mutable.
std::optional< PremultipliedColorU8 >	pixel (std::uint32_t x, std::uint32_t y) const
	Returns the pixel at (x, y), or nullopt if out of bounds.
std::optional< Pixmap >	cloneRect (const IntRect &rect) const
	Clones a rectangular region into a new Pixmap.
void	fill (const Color &color)
	Fills the entire pixmap with a color (premultiplied internally).
std::vector< std::uint8_t >	release ()
	Releases the raw byte buffer (premultiplied alpha).
std::vector< std::uint8_t >	releaseDemultiplied ()
	Releases the byte buffer after converting to straight (non-premultiplied) alpha. Use this for PNG encoding.

Static Public Member Functions
static std::optional< Pixmap >	fromSize (std::uint32_t width, std::uint32_t height)
	Creates a zero-filled pixmap. Returns nullopt for zero dimensions.
static std::optional< Pixmap >	fromVec (std::vector< std::uint8_t > data, IntSize size)
	Creates a pixmap from existing data. Returns nullopt if size mismatches.

Detailed Description

Create with Pixmap::fromSize() and obtain a MutablePixmapView via mutableView() for drawing. Call releaseDemultiplied() to extract straight-alpha bytes for PNG encoding.
