I am to load and draw a jpeg image in OpenGL.

Does any have routines for loading the jpeg ? Do fltk have code for that ?


FLTK has classes that load "all sorts" of images

https://www.fltk.org/doc-1.4/classFl__Image.html

For jpeg see:
https://www.fltk.org/doc-1.4/classFl__JPEG__Image.html

If you wonder how to access the image data to use it for drawing inOpenGL the following two HowTo's may be helpful:


https://www.fltk.org/articles.php?L466
https://www.fltk.org/articles.php?L468

The latter describes the opposite but maybe it can give you some cluesas well.


For drawing images in OpenGL I can't help.
