Using the changes from @gadomski along with some additional work, to get the generated bindings working again. Works on macOS and FreeBSD 11. A couple of hacks are needed for FreeBSD, but nothing too serious. Changed to use the libc prefix, and changed to use the generated enums. Fixes #22, #15, and #14 cargo test passes

magick-rust
A somewhat safe Rust interface to the ImageMagick system, in particular, the MagickWand library. Many of the functions in the MagickWand API are still missing, and those that are needed will be gradually added.
Dependenices
- Rust (~latest release)
- Cargo (~latest release)
- ImageMagick (version 6.9)
- Clang (version 3.5 or higher)
- Or whatever version is dictated by rust-bindgen
- Must have
pkg-configin order to link with MagickWand.
See the docs/Development_Setup.md file for details particular to each platform.
Build and Test
Pretty simple for now.
$ cargo build
$ cargo test
Example Usage
MagickWand has some global state that needs to be initialized prior to using the library, but fortunately Rust makes handling this pretty easy. In the example below, we read in an image from a file and resize it to fit a square of 240 by 240 pixels, then convert the image to JPEG.
use magick_rust::{MagickWand, magick_wand_genesis};
use std::sync::{Once, ONCE_INIT};
// Used to make sure MagickWand is initialized exactly once. Note that we
// do not bother shutting down, we simply exit when we're done.
static START: Once = ONCE_INIT;
fn resize() -> Result<Vec<u8>, &'static str> {
START.call_once(|| {
magick_wand_genesis();
});
let wand = MagickWand::new();
try!(wand.read_image("kittens.jpg"));
wand.fit(240, 240);
wand.write_image_blob("jpeg")
}
