Struct tiny_skia::PixmapMut

pub struct PixmapMut<'a> { /* fields omitted */ }

A container that references mutable premultiplied RGBA pixels.

Can be created from Pixmap or from a user provided data.

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

Implementations

impl<'a> PixmapMut<'a>

pub fn from_bytes(data: &'a mut [u8], width: u32, height: u32) -> Option<Self>

Creates a new PixmapMut from bytes.

The size must be at least size.width() * size.height() * BYTES_PER_PIXEL. Zero size in an error. Width is limited by i32::MAX/4.

The data is assumed to have premultiplied RGBA pixels (byteorder: ABGR).

pub fn to_owned(&self) -> Pixmap

Creates a new Pixmap from the current data.

Clones the underlying data.

pub fn width(&self) -> u32

Returns pixmap's width.

pub fn height(&self) -> u32

Returns pixmap's height.

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

Returns the mutable internal data.

Bytes are ordered as RGBA.

pub fn pixels_mut(&mut self) -> &mut [PremultipliedColorU8]

Returns a mutable slice of pixels.

Trait Implementations
