[osg-users] Copy a region of an image x,y,w,h / s,t,r

I want to load an image and then cut a region of that loaded image (1) and turn it into another image (2).

I don't understand the s_offset, t_offset and r_offset convention. Can you explain me what that is? I've tried to Google it.

tl;dr...I think copySubImage is what I want, but I don't understand the parameters.

Thank you!
