Raster

Raster provides a simplified API for processing pixels of raster images.

Creating Images

use raster::image::Image;

// Create an image from file
let image1 = raster::open("tests/in/sample.png").unwrap();
 
// Create a blank 100x100 image. Defaults to a black background.
let image2 = Image::blank(100, 100);

// Save blank
raster::save(&image2, "tests/out/test_blank.png");

A blank image:

Editing and Saving Images

use raster::image::Image;
use raster::editor;

// Create an image from file
let image = raster::open("tests/in/sample.png").unwrap();
 
// Resize an image to exactly 200x200 pixels
let image = editor::resize_exact(&image, 200, 200).unwrap();

// Save it
editor::save(&image, "tests/out/test_resize_exact.png");

Blending 2 Images

use raster::image::Image;
use raster::editor;

// Create images from file
let image1 = raster::open("tests/in/sample.jpg").unwrap();
let image2 = raster::open("tests/in/watermark.png").unwrap();
 
// Blend image2 on top of image1 using normal mode, opacity of 1.0 (100%), with image2 at the center, with 0 x and 0 y offsets. whew
let image3 = editor::blend(&image1, &image2, "normal", 1.0, "center", 0, 0).unwrap();

// Save it
editor::save(&image3, "tests/out/test_blend_normal.png");

See the modules, more specifically the editor module for more info.

Modules

color	A module for handling colors.
compare	A module for comparing images.
editor	A module for editing images.
filter	A module for filtering pixels.
image	A module for handling a raster image.
interpolate	A module for interpolating pixels.
transform	A module for 2D transformation.

Functions

open	Create an image from an image file. Returns raster::image::Image.
save	Save an image to an image file. The image type is detected from the file extension of the file name.
