View Full Version : CopyTexImage2D()

06-19-2003, 06:19 PM
I have tried to use CopyTexImage2D() to copy the image from frame buffer to a texture. When I use "GL_RGB" as the internal format, it is ok. However, if I use "GL_RGBA" instead, the color will become very poor. Is there anyone know how to fix the problem? Is it related to the internal format of the texture that I copied to?
Thanks a lot. ^_^
