About

stb_image_rust is Rust port of the stb_image.h, which is C library to load images in JPG, PNG, BMP, TGA, PSD and GIF formats.

It is important to note, that this project is port, not wrapper. Original C code had been ported to Rust. Therefore stb_image_rust doesnt require any native binaries.

The porting hasn't been done by hand, but using Hebron.

Sample Code

        // Load file into memory
        let mut f = File::open(path).expect("file not found");
        let mut contents = vec![];
        f.read_to_end(&mut contents);

	// Load the image
        let mut x: i32 = 0;
        let mut y: i32 = 0;
        let mut comp: i32 = 0;
        let img: *mut u8;
		
        unsafe {
            img = stb_image_rust::stbi_load_from_memory(
                contents.as_mut_ptr(),
                contents.len() as i32,
                &mut x,
                &mut y,
                &mut comp,
                stb_image_rust::STBI_rgb_alpha,
            );
        }
		
	// Do something with it
	...
		
	// Free the allocated memory
        unsafe {
            stb_image_rust::c_runtime::free(img);
        }
