- Preface
- -------
- Since some time there's need for either an extension
- or a complete rework of the IFF-ILBM file format: one can't
- store chunky graphics and storing more than 256 colors
- only is possible in a very unusual manner.
-
- All that does slow down usage on graphics card-equipped
- systems very much.
-
- And IFF-ILBM's compression is not very efficient, too.
-
- IFF-RGB8, IFF-DEEP and IFF-YUVN aren't good alternatives,
- since they're mainly designed for 24 Bit images and/or make
- use of uncommon compression algorithms and/or color spaces.
-
- A first step to pass this by was SuperView's internal
- graphics file format called "SVG" (SuperView Graphics),
- but it was not an IFF file format and somewhat proprietary
- in other terms, too.
-
- That's why IFF-RGFX has been defined.
-
- Look into the archive for developer information.
