These formats use the 295bd8deadSopenharmony_ci YCrCb color space to represent pixels before compression and after 305bd8deadSopenharmony_ci decompression. 315bd8deadSopenharmony_ci 325bd8deadSopenharmony_ciIssues 335bd8deadSopenharmony_ci 345bd8deadSopenharmony_ci - How should the color spaces be specified? 355bd8deadSopenharmony_ci 365bd8deadSopenharmony_ci - Are either DVC or DVCPRO copyrighted or trademarked names? 375bd8deadSopenharmony_ci 385bd8deadSopenharmony_ciNew Procedures and Functions 395bd8deadSopenharmony_ci 405bd8deadSopenharmony_ci None. 415bd8deadSopenharmony_ci 425bd8deadSopenharmony_ciNew Tokens 435bd8deadSopenharmony_ci 445bd8deadSopenharmony_ci Accepted by the <param> parameter of PixelStoref and PixelStorei 455bd8deadSopenharmony_ci when the <pname> parameter is COMPRESSION_TYPE_SGIX: 465bd8deadSopenharmony_ci 475bd8deadSopenharmony_ci DVC_SGIX 485bd8deadSopenharmony_ci DVCPRO_SGIX 495bd8deadSopenharmony_ci 505bd8deadSopenharmony_ciAdditions to Chapter 2 of the 1.0 Specification (OpenGL Operation) 515bd8deadSopenharmony_ci 525bd8deadSopenharmony_ci None. 535bd8deadSopenharmony_ci 545bd8deadSopenharmony_ciAdditions to Chapter 3 of the 1.0 Specification (Rasterization) 555bd8deadSopenharmony_ci 565bd8deadSopenharmony_ci 3.6.1 Pixel Storage Modes 575bd8deadSopenharmony_ci 585bd8deadSopenharmony_ci DVC_SGIX and DVCPRO_SGIX are added to the Valid Range of 595bd8deadSopenharmony_ci UNPACK_COMPRESSION_TYPE in Table 3.1. 605bd8deadSopenharmony_ci 615bd8deadSopenharmony_ciAdditions to Chapter 4 of the 1.0 Specification (Per-Fragment Operations 625bd8deadSopenharmony_ciand the Frame Buffer) 635bd8deadSopenharmony_ci 645bd8deadSopenharmony_ci 4.3.2 Reading Pixels 655bd8deadSopenharmony_ci 665bd8deadSopenharmony_ci DVC_SGIX and DVCPRO_SGIX are added to the Valid Range of 675bd8deadSopenharmony_ci PACK_COMPRESSION_TYPE in Table 4.5. 685bd8deadSopenharmony_ci 695bd8deadSopenharmony_ci 705bd8deadSopenharmony_ciAdditions to Chapter 5 of the 1.0 Specification (Special Functions) 715bd8deadSopenharmony_ci 725bd8deadSopenharmony_ci None. 735bd8deadSopenharmony_ci 745bd8deadSopenharmony_ciAdditions to Chapter 6 of the 1.0 Specification (State and State Requests) 755bd8deadSopenharmony_ci 765bd8deadSopenharmony_ci 775bd8deadSopenharmony_ciAdditions to the GLX Specification 785bd8deadSopenharmony_ci 795bd8deadSopenharmony_ci 805bd8deadSopenharmony_ciGLX Protocol 815bd8deadSopenharmony_ci 825bd8deadSopenharmony_ci 835bd8deadSopenharmony_ciErrors 845bd8deadSopenharmony_ci 855bd8deadSopenharmony_ci XXX 865bd8deadSopenharmony_ci 875bd8deadSopenharmony_ciNew State 885bd8deadSopenharmony_ci 895bd8deadSopenharmony_ci None. 905bd8deadSopenharmony_ci 915bd8deadSopenharmony_ciNew Implementation Dependent State 925bd8deadSopenharmony_ci 935bd8deadSopenharmony_ci None. 94
