Browser Side Photo Editing Library

Currently I'm searching for a free solution to simple edit some photos at the users browser. Resizing and Cropping would 开发者_如何学Cbe mandatory. I'm not searching for an online service (for example SUMO or PIXLR which are great), because I want to include the software into a WYSIWYG Editor.

JavaScript would be really nice, but it would have to work in IE 8. Pixastic is a great example, but works only in modern browsers (not IE 8 :-/)

Any suggestions what I could use?

Maybe setting up some kind of image processing service with ImageMagick and communicating with it through AJAX could also be an solution? Has anyone gained some experience with such a solution?

If you are open to server side image processing, then you can look at some basic image transformations that Google app engine provides.

You can try MarvinJ for Javascript image processing in the browser side. Very easy to use it:

// Load image and manipulate color channel
image.load("https://i.imgur.com/ZcCe0eC.jpg", function(){
    image.draw(canvasA);
    Marvin.colorChannel(image, image, 14, 0, -8);
    image.draw(canvasB);
});

Basically, it loads the pixel data for an image in the web and provides many algorithms to manipulate it.

Few examples (JSFiddle included):
