PCD2IFF24 version 1.05 Jan-12-1998
Allenbrand Brice - Ringard' Production.
-> Shell-only.
-> Kick 2.04 required.
IMPORTANT NOTE
--------------
A PPC version is now included. It is my first attempt to produce such
code. I don't have any PPC board to test the results, so please report me
any bugs !
INTRO:
------
PCD2IFF24 is a PhotoCD to IFF24 converter.
Why another one ? because it's :
I 1) The only that does it in all the PCD resolutions. I
M 2) The only that doesn't need any alien library. M
P 3) The only that doesn't need any stack change. P
O 4) The only that uses Amiga routines for maximum speed. O
R 5) The only that uses an enhanced memory management system. R
T 6) The only that take care for PAL/NTSC or ECS/AGA. T
A 7) The only without Enforcer hits. A
N 8) The only that can be used with only 512Kb of memory (!!) N
T 9) The smallest T
! 10) No FPU needed !
You only must have at least the Kick 2.04 or greater with enough memory.
USAGE:
------
PCD2IFF24 InFile/A,OutFile/A,SIZE/N,BW/S,OVSKP/S
InFile : the PCD file. REQUIRED
OutFile : the IFF file. REQUIRED
Size 1 (default) 192x128
2 384x256
3 768x512
4 1536x1024
5 3072x2048
BW : extract a 256 greyscaled picture.
OVSKP : uses the colors of the overneighboor picture.
MORE:
-----
_In BW mode, you only need 1/3 of memory amount required for the
color mode.
_The OVSKP mode doesn't use more memory, but the quality is better.
_The conversion time depends on the memory amount of your Amiga.
_The IFF saving routines can handle 3 different buffers depending
on your available memory. Off course ByteRunComp1 is used.
_PCD2IFF24 is only a converter. It doesn't do much more, because
there exist enough image processing programs and they will do it
better.
_PCD2IFF24 can be used with VMM
