[Bug 10787] I don't see a way to save the canvas data as a BMP or JPEG or anything else that can then be uploaded via a FORM to a web server. This is a requirement, I woudl think.

Check out the toDataURL() function.  It saves the canvas data as a PNG by
default, though implementations may offer the ability to save it in other
formats such as JPEG or BMP.

You can stuff this data in a form the obvious way, and decode it into an actual
image file on the server easily.
