Save image with ocaml graphics

Question

Answer 1

I'm going to assume that you are talking about the Graphics module in ocaml.

You should notice that the Graphics module isn't for creating and processing images. You can of course call Graphics.dump_image if you've already gone ahead and wrote something that produces the Graphics.image type. This will produce a color array array , where color is a packed integer in the format, 0xRRGGBB.

After some other conversion functions you should call upon camlimages to produce your image, and there is a code sample from another question .
