Struct pix::Raster

pub struct Raster<F: PixFmt> { /* fields omitted */ }

A raster image with owned pixel data. If the pixel data must be owned elsewhere, consider using RasterB.

Example

use pix::{Raster, Alpha8};
let mut r: Raster<Alpha8> = Raster::new(10, 10);
r.set_pixel(2, 4, Alpha8::new(255));

Methods

impl<F: PixFmt> Raster<F>

pub fn new(width: u32, height: u32) -> Raster<F>

Create a new raster image.

• F Pixel format.
• width Width in pixels.
• height Height in pixels.

pub fn width(&self) -> u32

Get raster width.

pub fn height(&self) -> u32

Get raster height.

pub fn pixel(&self, x: u32, y: u32) -> F

Get one pixel value.

pub fn set_pixel(&mut self, x: u32, y: u32, p: F)

Set one pixel value.

pub fn as_slice(&self) -> &[F]

Get the pixels as a slice.

pub fn as_slice_mut(&mut self) -> &mut [F]

Get the pixels as a mutable slice.

pub fn as_u8_slice(&self) -> &[u8]

Get the pixels as a u8 slice.

pub fn as_u8_slice_mut(&mut self) -> &mut [u8]

Get the pixels as a mutable u8 slice.

pub fn clear(&mut self)

Clear all pixels.

pub fn mask_over(&mut self, mask: &Raster<Alpha8>, x: i32, y: i32, clr: F)

Blend pixels with an alpha mask.

• mask Alpha mask for compositing.
• x Left position of alpha mask.
• y Top position of alpha mask.
• clr Color to composite.
