OpenGL Internal Texture formats
Author
What kind of Texture format is INTENSITY? I know that luminance is grayscale, but what''s intensity?
Is it like, a combination of luminance and alpha?
It stores a single (1 byte) value and uses that for both color (greyscale) and alpha.

Thanks, that's what I thought. Can anyone give an example of when you'd want to use it?
Also, according to this Table There are 4, 8, 12 & 16 bit versions of INTENSITY

The only thing I''ve used it for is storing single color fonts.

many uses for greyscale images, the biggest advantage is the memory requirements are far less than using a RGB or RGBA image of the same quality
