I've found this function very useful when wanting to manipulate an existing image. An example would be to simply flip an image (source code here: http://www.coderprofile.com/source-code/372/ ) The principle i use a lot is to scan through an image pixel by pixel performing some kind of action on that pixel... and then saving the newly created pixel on to a new canvas ready to display to the browser. The only problem i find is speed... so some kind of caching mechanism and dimensions limitation on images that are processed is recommended for high traffic use.
