Required Formats section says the following:
"... The implementation is forbidden to lose information from these formats. So, while an implementation may choose to turn GL_RGB4 into GL_R3_G3_B2, it is not permitted to turn GL_RGB8 into GL_RGB4 internally."
Is this correct? Going from GL_RGB4 to GL_R3_G3_B2 is losing information, yes?
- Perhaps you misunderstood what is being said. Yes, that conversion loses information. The point of the text is that it is allowed to lose information, because GL_RGB4 is not a required image format. GL_RGB8 is a required image format, so it is not allowed to lose information.
