Image processing imageproc

Overview

ImageProc

Maintainers: @chyh1990

Note: this project is under active depvelopment, API may change!

imageproc is a advanced image proccessing library for the Rust language in order to provide:

generic pixel, image, geometry data structure alike OpenCV
Image IO for variable image file format
image transformations
image processing routines, e.g. convolution, gaussian blur, etc.
canvas and rasterization (TBD)

This library is inspired by the following projects:

Usage

Adding the following to the Cargo.toml in your project:

[dependencies.imageproc]
git = "https://github.com/chyh1990/imageproc.git"

and import using extern crate:

extern crate imageproc;

Most data structures and routines are exposed uder imageproc prefix:

extern crate imageproc;

use std::path::Path;
use imageproc::image::*;
use imageproc::conv;
use imageproc::imageio::{ImageIO, FreeImageIO}; 

fn main() {
	let img: ImageBgra = FreeImageIO::from_path(&Path::new("cat.jpg")).unwrap();
	let out = conv::gaussian_blur(&img, 11, 0f32);

	let target = Path::new("out.png");
	FreeImageIO::save(&target, &out).unwrap();
}

Supported Image Format

imageproc use cross-platform native library to decode/encode images. The only supported backend is FreeImage, it includes decoders for most image formats, and encoders for most common used formats.

Fails to compile

Hi,

I get the following error when trying to compile imageproc:

$ cargo build
   Compiling imageproc v0.1.0 (file:///Users/phi/Documents/workspace/rust-imageproc)
failed to run custom build command for `imageproc v0.1.0 (file:///Users/phi/Documents/workspace/rust-imageproc)`
Process didn't exit successfully: `/Users/phi/Documents/workspace/rust-imageproc/target/debug/build/imageproc-f73ade026b903961/build-script-build` (exit code: 101)
--- stdout

--- stderr

I have written a sobel convolution kernel and would like to submit a pull request for this but I'd like to test it before I do that.
