Short: Datatype for Photo-CD Images (43.9)
Uploader: astegema@ix.urz.uni-heidelberg.de (Achim Stegemann)
Author: astegema@ix.urz.uni-heidelberg.de (Achim Stegemann)
Type: util/dtype
Version: 43.9
Requires minimum:
* OS 3.0
* MC68020
* A mounted PIPE: handler !!
* The PCD decoder 'pcdtoppm' in your path (included).
* ixemul.library V39 (not included, V41 or higher is recommended).
* render.library V29 or better (included).
Additionally recommended:
* CyberGraphX with picture.datatype V43 for 24-bit images.
* MUI 3.8 for the preferences.
With the help of the pcd.datatype, your datatype sytem is able to read Photo-CD images.
This archive is Freeware !
Do with it what you want, as long as you do not remove any files from this archive !
Changes since V43.7:
20-Oct-98 V43.9
* Changed flags in memory allocation, so it can be used with VMM (Virtual Memory Manager).
* Included source-code in C++
* Corrected the DOS template for prefs.
* Improved libinit.
The full render.library archive is also available in Aminet:dev/misc.

Warning:
It seems, that this datatype does not work with Picasso96, but this is not for sure !
If you use Picasso96, please try it and report me your result.
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.
