I'm working in the idea to make a captcha (system generating picts containing text you should type to prove you're not a bot...) using GTK+ 2 and I'm seeking the right object to create an image from scratch and then saving it in a file.
I had a look in the tutorial and in the ref manual and 3 objects seems to be ok: gtk drawing_area, gtk_image, and Gdk Pixbuf.
I don't know really how I should make the choice (and I may forget another object I didn't see...).
What I have to do with the object is:
* creating a pict with an uniform background
* having the ability to do standard operations (points, polygons, etc...)
* having the ability to read a pixel
* having the ability to display text with a choosen font and size
* being able to save the final image...
* the rest to produce a good (I hope) captcha would be my work...
Has anybody any reasons for a choice or a pointer to relevant docs to make the choice?
Tony
