 Abstract:

 RGFX currently supports compressed and uncompressed:

  -  planar graphics                    (  <=     8 Bit integer)
  -  chunky graphics                    (  <=     8 Bit integer)
  -  15 Bit graphics as  RGB            (     3x  5 Bit integer)
  -  16 Bit graphics as ARGB            (1  + 3x  5 Bit integer)
  -  24 Bit graphics as  RGB triples    (     3x  8 Bit integer)
  -  32 Bit graphics as ARGB quadruples (8  + 3x  8 Bit integer)
  -  48 Bit graphics as  RGB triples    (     3x 16 Bit integer)
  -  64 Bit graphics as ARGB quadruples (16 + 3x 16 Bit integer)
  -  96 Bit graphics as  RGB triples    (     3x 32 Bit float  )
  - 128 Bit graphics as ARGB quadruples (32 + 3x 32 Bit float  )

 With optional PNG-style alpha channel for each 24/48/96 bit pixel
 or a single transparent color for colormapped images (upto 8 bit).
 HDR compliance via 32 bit IEEE float support.
 
    (* integer formats using full range (0 .. max),
       float formats normalized (0.0f .. 1.0f)

 Typical structure of a RGFX file (recommended):

     FORM-RGFX

       RGHD     image header
       RSCM     viemode information
       RDIP     DIPF information
       RCOL     color and transparency information
       RFLG     optional; further flags       
       NAME     optional
       AUTH     optional
       ANNO     optional
       Copy     optional
       EXIF     optional; see IFF-META spec
       IPTC     optional; see IFF-META spec
       XMP0     optional; see IFF-META spec
       XMP1     optional; see IFF-META spec
       GEOT     optional; see IFF-META spec       
       GEOF     optional; see IFF-META spec       
       ICCP     optional; see IFF-META spec       
       ICCN     optional; see IFF-META spec       
       GAMA     optional; see IFF-META/ILBM64 spec       
       CHRM     optional; see IFF-META/ILBM64 spec       
       SRGB     optional; see IFF-META/ILBM64 spec       
       RBOD     the graphics itself

  All additional (optional) chunks should appear
  somewhere between RCOL and RBOD.

  Please refer to rgfx.h for the chunk specifications
  and permitted standard chunks as far as not specified
  elsewhere.

  A few optional third party RGFX chunks are also discussed.

  These are not part of the format specification and
  should be considered  private, proprietary extensions.
