I would very much like to try out to come up with a routine to manipulate pixels on the basis of the "text of image" property (to compare it with the possibilities the imagedata format offers). Where could I find background information for such an approach?
I warn you ahead of time that it will be ugly and you will probably pull out much of your hair. ;-) That being said, I think the best approach is to choose a format to work with, then consult the standards documentation for that format.
For example, you might choose to work with JPEG images. I think John Craig mentioned <http://www.jpeg.org> as a good URL to start with, although I think the Wikipedia page on JPEG is mmore informative <http://en.wikipedia.org/wiki/JPEG>. The text property of the image is in the format specified by the image's paintCompression, so for practical purposes you treat this property as though it were a JPEG file, decoding the data and then performing whatever transformation you need on it, then re-encoding it and putting the result into the image. (This is essentially what the engine is already doing when it displays a JPEG image, allows you to change it using paint tools or imageData, and saves the changed image.)
