Doing image processing in the browser using GWT

I want to write a simple web application in which image synthesis is done in the browser. I will have a server that serves procedural image information (expressions), and the clients should be able to use these messages to generate and display images. Can t开发者_Python百科his sort of task be done entirely in the web browser (using GWT, preferably)?

You will have some major browser restrictions, but you can try using either HTML5 canvas or I have also noticed that the Firefox implementation of ImageResource compiles to a url containing data: followed by some sort of bitmap, so you could support non-html5 versions of FF. However I believe IE will be out of the question until IE9. I believe the thin image editing client used in Picassa web albums uses server-side rendering. Also, eventually you might want to look into the Chrome native API if you are doing any heavy image processing.
