glLoadIdentity says

GL_INVALID_OPERATION is generated if glLoadIdentity is executed between the execution of glBegin and the corresponding execution of glEnd.

But GL_INVALID_OPERATION is a flag returns by glGetError.

My question is, when should we call glGetError ( in order to know whether we are calling opengl in correct sequence)?

How can I get the palette of an 8-bit surface in SDL.NET/Tao.SDL?

as seen on Game Development - Search for 'Game Development'
I'm looking to get the palette of an 8-bit surface in SDL.NET if possible, or (more than likely) using Tao.SDL. This is because I want to do palette swapping with the palette directly, instead of blitting surfaces together to replace colours like how you would do it with a 32-bit surface. I've gotten… >>> More
