Based on node-imagemagick
Requires imagemagick CLI tools to be installed. There are numerous ways to install them. For instance, if you're on OS X you can use Homebrew: brew install imagemagick.
Expands upon orignal by adding a much more Object Oriented design to more closely mimic existing libraries. New functions and features will be continually added.
im = new ImageMagick();
//small red dot
im.readImageDataUrl('data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==', function(image){
new_width = 10;
new_height = 10;
im.resizeImage(new_width, new_height, IMAGE_MAGICK_FILTER_LANCZOS, 0, function(){
console.log(image.data_url); //return our new data_url, can also write the file out, get binary, etc
});
});
im.readImage('./blue-bottle-coffee.jpg', function(image){
//can read info like image width and height if we want to
src_width = image.width;
src_height = image.height;
new_width = 100;
new_height = 10;
//where to crop image from
var x = 0;
var y = 10;
im.cropImage(new_width, new_height, x, y, function(){
console.log(image.data_url);
});
});
