Parameters
| Variables | Description |
|---|---|
| target |
Specifies the target texture. Must be
GLU_TEXTURE_2D
.
|
| internalFormat |
Requests the internal storage format of the texture image. The most
current version of the SGI implementation of GLU does not check this
value for validity before passing it on to the underlying OpenGL
implementation. A value that is not accepted by the OpenGL
implementation will lead to an OpenGL error. The benefit of not
checking this value at the GLU level is that OpenGL extensions can add
new internal texture formats without requiring a revision of the GLU
implementation. Older implementations of GLU check this value and
raise a GLU error if it is not 1, 2, 3, or 4 or one of the following
symbolic constants:
GLU_ALPHA

GLU_ALPHA4

GLU_ALPHA8
