Note to frmzero2hero: sizing up the texture to the nearest power of two when you load it is an easy solution, as someone suggested. Don''t stretch the image, just fill the additional space with black or white. Adjust your texture coordinates so that they match the size of the valid data in the surface, and you''re done.

I actually implemented that straight into my image loader. It always sizes images to powers of 2, since I''m always using them as textures anyway. Sure, I''m throwing out memory by the bucketload, but these are research projects anyway, so it''s not like I need to run them at 150FPS on a 20 Mhz machine.

Small point, to everyone who keeps suggesting gluBuild2DMipmaps:

I do not want to strech or shrink the resolution ..ie i want to display it as it is.

As others have suggested, I would use a 1024x1024 texture with an 800x600 image in the corner. Render it with GL_NEAREST filtering, scaling your tex coords appropriately, and you''re away. The only problem with this is if you''ve got very limited video card memory or if there''s a texture size limit. Decent (ie: not 3dfx) cards shouldn''t have a problem with this.

Where in the SDK does it say DDraw forces powers of 2 for regular offscreen surfaces?
