This is a port of rgfx.datatype by Achim Stegemann. IFF-RGFX is an Amiga picture
format that allows compressing the image data through any of the compressors
available to xpkmaster.library.

Install:

1. copy rgfx.datatype to SYS:Classes/DataTypes/
2. copy RGFX(|.info) to SYS:Devs/DataTypes/
3. copy DT2RGFX to C:

DT2RGFX can be used to convert any image format supported by datatypes into
.rgfx. F.e. to convert the image "image.pcx" and pack using gzip:

DT2RGFX image.pcx image.rgfx XPK=gzip

RGFXPrefs is not ported so you will have to use the m68k version if you need it.

OS4 native render.library:
http://neoscientists.org/~tmueller/binarydistillery/renderlib.lha

xpkmaster.library glue file (needed if using the m68k xpkmaster.library):
http://os4depot.net/index.php?function=showfile&file=library/misc/xpkmaster-glue
file.lha

-- original readme --

Requires minimum:
 * OS 3.0
 * MC68020
 * xpkmaster.library V5
 * render.library V30 (included).

Additionally recommended:
 * CyberGraphX with picture.datatype V43 for 24-bit images.
 * MUI 3.8 for the preferences.

If you run OS 3.5, it is recommended to install the RGFX-DT35 archive !!

With the help of the rgfx.datatype, your datatype sytem is able to read images
coded in the new IFF-RGFX-Format created by Andreas Kleinert.

This archive is freeware !
Do with it what you want, as long as you do not remove any files from this
archive !

The archive also contains the utility 'DT2RGFX'. This converts a datatype
picture to the new IFF-RGFX-Format !

The datatype supports the DTM_WRITE-RAW method, to save in own format.

Changes since V43.16:
* Fixed a bug in the installer script. Wrong CPU version of render.library was
  copied.

Changes since V43.15:
* Cleaned up ramlib-stuff (thx to Oliver Roberts).
* V40-mode dithering didn't work, was just a black bitmap.
