Struct PixmapMut 

pub struct PixmapMut<'a> {
    width: u16,
    height: u16,
    buf: &'a mut [u8],
}

A mutable view into premultiplied RGBA8 pixmap data.

Fields

width: u16

Width of the pixmap in pixels.

height: u16

Height of the pixmap in pixels.

buf: &'a mut [u8]

Buffer of the pixmap in RGBA8 format.

Implementations

impl<'a> PixmapMut<'a>

pub fn new(width: u16, height: u16, buf: &'a mut [u8]) -> Option<Self>

Create a new mutable pixmap view.

Returns None if buf is not exactly width * height * 4 bytes long.

pub fn width(&self) -> u16

Return the width of the pixmap.

pub fn height(&self) -> u16

Return the height of the pixmap.

pub fn data_mut(&mut self) -> &mut [u8]

Returns a mutable reference to the underlying data as premultiplied RGBA8 bytes.
