JavaScript Canvas image processing library

Question

I've been working on a project that I forever could not complete because of something I don't know how to implement.

Does anyone know any image processing libraries (must use Canvas) that can allow me to specifically at least do the following:

• Add borders to drawn images

• Clip out parts of images

• ¹Resizing: Resizing just the image drawn and not the canvas element. (scale to fit inside the canvas without ever stretching the image)

  Like this but without the drag handling: http://phrogz.net/tmp/canvas_zoom_to_cursor.html

• Mirror images in any of the four direction (flip/translation)

¹Some of these I can do. This is the main feature I am looking for.

The reason I want a library at this time is because I'm tired of typing code. It's not laziness but rather too much work but that's off topic.

Thanks
