NOTE:
This IFF-RGFX datatype is for OS 3.5 only !!
Download util/dtype/RGFX-DT.lha under OS 3.0 or OS 3.1 !!

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.

Important note about the source code:
*************************************

The source has been written in C++ using Maxon-C++ V3.
You will find several instructions a bit strange as I have converted all C-style OS-structures
to C++ OS-structures.
E.g.

struct Library
{
struct Node lib_Node;
UBYTE lib_Flags;
UBYTE lib_pad;
UWORD lib_NegSize;
UWORD lib_PosSize;
UWORD lib_Version;
UWORD lib_Revision;
APTR lib_IdString;
ULONG lib_Sum;
UWORD lib_OpenCnt;
};

has been converted to

struct Library:Node // !!!!!
{
UBYTE lib_Flags;
UBYTE lib_pad;
UWORD lib_NegSize;
UWORD lib_PosSize;
UWORD lib_Version;
UWORD lib_Revision;
APTR lib_IdString;
ULONG lib_Sum;
UWORD lib_OpenCnt;
};

This simplifies the code as I don't always need to cast variables to fit arguments
in functions.
Additionally C++ allows to leave away the 'struct' keyword !

If you like to recompile the source-code for your compiler, you need to adjust the
source-code to C. But this should be no problem.
