Hello everyone,

I was wondering whether anyone knows of a good tutorial on how to use images exported from GIMP as C-Source in OpenGL programs?

I want to display an image of a gradient created in GIMP as a 2D bitmap, but I'm not sure how to load the image data from the C-Source file. I think I need to use the glDrawPixels function, but I'm not sure. Can anyone help?

Have you tried gdk-pixbuf-csource(1) ?

have you tried the AA plug-in?

i have never worked with that option, but i find many of the aa options are fairly self explanatory once you start working with it.

two things. 1) the AA plug-in will only build if you have the aalib and configure finds it.
2) it will only work on grayscale images and
2.5) Ximian doesn't build their gimp with this plug-in.

good luck!

let me know how it goes ...

last mail from me, sorry.

C-Source is an option in the Save As Dialog. It prolly will not help you as it "makes" them.

here is a screenshot of the dialog: http://carol.gimp.org/~carol/screens/treva3/csource-dialog.png

and here is a file i save with it (a mondrain) http://carol.gimp.org/~carol/screens/treva3/comp-3.c

it takes rgb images (not grayscale) and the "image" can be opened with a text editor (not unlike xpm)

sorry for all of my confusion
