Struct tiny_skia::PixmapRef

source · [−]

pub struct PixmapRef<'a> { /* private fields */ }

Expand description

A container that references premultiplied RGBA pixels.

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

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

Implementations

source

impl<'a> PixmapRef<'a>

source

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

Creates a new PixmapRef 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: RGBA).

source

pub fn to_owned(&self) -> Pixmap

Creates a new Pixmap from the current data.

Clones the underlying data.

source

pub fn width(&self) -> u32

Returns pixmap’s width.

source

pub fn height(&self) -> u32

Returns pixmap’s height.

source

pub fn data(&self) -> &'a [u8]ⓘNotable traits for &mut [u8]`impl<'_> Write for &mut [u8]impl<'_> Read for &[u8]`

Returns the internal data.

Byteorder: RGBA

source

pub fn pixel(&self, x: u32, y: u32) -> Option<PremultipliedColorU8>

Returns a pixel color.

Returns None when position is out of bounds.

source

pub fn pixels(&self) -> &'a [PremultipliedColorU8]

Returns a slice of pixels.

source

pub fn clone_rect(&self, rect: IntRect) -> Option<Pixmap>

Returns a copy of the pixmap that intersects the rect.

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

source

pub fn encode_png(&self) -> Result<Vec<u8>, EncodingError>

Encodes pixmap into a PNG data.

source

pub fn save_png<P: AsRef<Path>>(&self, path: P) -> Result<(), EncodingError>

Saves pixmap as a PNG file.
