Struct Pixmap

pub struct Pixmap { /* private fields */ }

A pixmap of premultiplied RGBA8 values backed by u8.

Implementations

impl Pixmap

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_as_u8_slice(&self) -> &[u8]

Returns a reference to the underlying data as premultiplied RGBA8.

The pixels are in row-major order. Each pixel consists of four bytes in the order [r, g, b, a].

pub fn data_as_u8_slice_mut(&mut self) -> &mut [u8]

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

The pixels are in row-major order. Each pixel consists of four bytes in the order [r, g, b, a].

pub fn take_u8(self) -> Vec<u8>

Consume the pixmap, returning the data as the underlying Vec of premultiplied RGBA8.

The pixels are in row-major order.

pub fn take_png(self) -> Vec<u8>

Encode the pixmap into a PNG file.

Trait Implementations

impl Clone for Pixmap

fn clone(&self) -> Pixmap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Pixmap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
