| 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: |

| 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. |

| Dependencies on SGI_color_table |
| |
| SGI_color_table is required. |
| This extension adds another table to the list specified by 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. |
