	Name	Description
in	target	Target texture
in	level	Mipmap level of the data to load
in	internalformat	Internal format of lookup table data (the same as format)
in	width	Size of entries in the lookup table
in	border	Border width (only 0 is valid)
in	format	Format of lookup table data
in	type	Type of lookup table data
in	pixels	Pointer to the lookup table data

No values are returned.

Configures lookup table data.

You can set target to GL_LUT_TEXTUREi_DMP. The value of i is greater than or equal to 0 and is at least one less than the value obtained from glGetIntegerv with GL_MAX_LUT_TEXTURES_DMP specified.

Specify 0 for level.

Set internalformat to GL_LUMINANCEF_DMP.

For width, specify the lookup table's entry size. This must not be larger than the value that is obtained from glGetIntegerv with GL_MAX_LUT_ENTRIES_DMP specified.

Specify 0 for border.

Set format to GL_LUMINANCEF_DMP.

Set type to GL_FLOAT.

For pixels, specify a pointer to the lookup table data.

This function generates the following errors.

GL_INVALID_ENUM	The target, format, internalformat, or type argument was set to an invalid value.
GL_INVALID_VALUE	The level, border, or width argument was set to an invalid value.
GL_INVALID_OPERATION	0 was bound to the lookup table texture target specified by target.
