Overview


    This extension defines a color table that is applied immediately
after the pixel transformation operation.

New Procedures and Functions


    None.

New Tokens


    Accepted by the <cap> parameter of Enable, Disable, and IsEnabled, and
by the <target> parameter of ColorTableSGI, ColorTableParameterivSGI,
ColorTableParameterfvSGI, GetColorTableSGI, GetColorTableParameterivSGI,
and GetColorTableParameterfvSGI:

PIXEL_TRANSFORM_COLOR_TABLE_EXT

Accepted by the <target> parameter of ColorTableSGI,
GetColorTableParameterivSGI, and GetColorTableParameterfvSGI:

PROXY_PIXEL_TRANSFORM_COLOR_TABLE_EXT


Additions to Chapter 3 of the 1.1 Specification (Rasterization)


    The operation of the PIXEL_TRANSFORM_COLOR_TABLE is added to the GL
Specification in section 3.6.3, "Rasterization of Pixel Rectangles".
This color table behaves in the manner described in the SGI_color_table
extension, and it is located immediately after the pixel transformation
operation. This color table can be enabled or disabled separately from
the pixel transformation operation by calling Enable or Disable with
PIXEL_TRANSFORM_COLOR_TABLE. It can be modified using the procedures
defined in the SGI_color_table extension. The proxy version of this table
can be set or queried by using a target value of
PROXY_PIXEL_TRANSFORM_COLOR_TABLE.


Additions to the GLX Specification


    None


Dependencies on SGI_color_table

This new table can be manipulated using the procedures defined by
SGI_color_table.

EXT_pixel_transform is required. This extension builds on the capabilities
defined by EXT_pixel_transform.
