| SGIX_image_compression is required. |
| |
| Overview |
| |
| This extension creates a new compression type to be used with |
| SGIX_image_compression which allows the decompression from- and |
| compression to client data stored in the formats described by the DVC |
| and DVCPRO digital video compression standards. These formats use the |
| YCrCb color space to represent pixels before compression and after |
| decompression. |
| |
| Issues |
| |
| - How should the color spaces be specified? |
| |
| - Are either DVC or DVCPRO copyrighted or trademarked names? |
| |
| New Procedures and Functions |
| |
| None. |
