pub struct Pixmap { /* private fields */ }
Expand description

A container that owns premultiplied RGBA pixels.

The data is not aligned, therefore width == stride.

Implementations

Allocates a new pixmap.

A pixmap is filled with transparent black by default, aka (0, 0, 0, 0).

Zero size in an error.

Pixmap’s width is limited by i32::MAX/4.

Decodes a PNG data into a Pixmap.

Only 8-bit images are supported. Index PNGs are not supported.

Loads a PNG file into a Pixmap.

Only 8-bit images are supported. Index PNGs are not supported.

Encodes pixmap into a PNG data.

Saves pixmap as a PNG file.

Returns a container that references Pixmap’s data.

Returns a container that references Pixmap’s data.

Returns pixmap’s width.

Returns pixmap’s height.

Fills the entire pixmap with a specified color.

Returns the internal data.

Byteorder: RGBA

Returns the mutable internal data.

Byteorder: RGBA

Returns a pixel color.

Returns None when position is out of bounds.

Returns a mutable slice of pixels.

Returns a slice of pixels.

Consumes the internal data.

Byteorder: RGBA

Returns a copy of the pixmap that intersects the rect.

Returns None when Pixmap’s rect doesn’t contain rect.

Draws a filled rectangle onto the pixmap.

See PixmapMut::fill_rect for details.

Draws a filled path onto the pixmap.

See PixmapMut::fill_path for details.

Strokes a path.

See PixmapMut::stroke_path for details.

Draws a Pixmap on top of the current Pixmap.

See PixmapMut::draw_pixmap for details.
