Crate pix

Expand description

Library for image conversion and compositing.

A raster image can be cheaply converted to and from raw byte buffers, enabling interoperability with other crates.

Many image formats are supported:

Bit depth: 8- or 16-bit integer and 32-bit float
Alpha: premultiplied or straight
Gamma: linear or sRGB
Color models:
- RGB / BGR (red, green, blue)
- CMY (cyan, magenta, yellow)
- Gray (luma / relative luminance)
- HSV (hue, saturation, value)
- HSL (hue, saturation, lightness)
- HWB (hue, whiteness, blackness)
- YCbCr (used by JPEG)
- Matte (alpha only)

Compositing with blending operations is supported for premultiplied images with linear gamma.

HWB Color Example

use pix::hwb::SHwb8;
use pix::rgb::SRgb8;
use pix::Raster;

let mut r = Raster::with_clear(256, 256);
for (y, row) in r.rows_mut(()).enumerate() {
    for (x, p) in row.iter_mut().enumerate() {
        let h = ((x + y) >> 1) as u8;
        let w = y.saturating_sub(x) as u8;
        let b = x.saturating_sub(y) as u8;
        *p = SHwb8::new(h, w, b);
    }
}
// Convert to SRgb8 pixel format
let raster = Raster::<SRgb8>::with_raster(&r);
