- This is Version 0.5 of hpcdtoppm, Hadmut's pcd to ppm converter.
- It has this name to be distinguishable in case someone
- else is producing a program also called pcdtoppm.
-
- Read the README.TOO and edit the config.h and the Makefile !
-
- This program converts Photo-CD-Images to the ppm-Format of
- pbmplus. You can compile the program in two ways:
-
- 1. Use its own ppm-writing-routines. In this case
- you don't need ppm-includes or libraries. You
- have to define macro 'OWN_WRITE' in the source or
- by compiler-option. I am not sure, whether the
- format of the ppm-header is the same on non-unix
- machines. If you get problems with line-endings
- (things like CR, LF, CR/LF), modify the macro
- PPM_Header.
-
- 2. You can use the pbmplus-routines. In this case
- you need some files from the pbmplus package to compile:
-
- ppm.h pgm.h pbm.h pbmplus.h libppm.a libpgm.a libpbm.a
-
-
- IMPORTANT: Some older versions of the gcc have problems with
- optimization. They produce buggy code. This code will not
- die with 'segmentation fault' or something like that, it
- just produces damaged images.
-
- I did not have detailed information of the file-format and
- most of my information i got by starring at the hex-dumps
- of an image file. So i am not absolutly sure, whether it
- works on all Photo-CDs, because there are some bytes in
- the header which i don't understand. But it works on
- my Photo-CD.
-
- Note that you will get a 24 bit image. You can view these
- files with xv, but if you have an 8-bit-screen you will
- sometimes have some color-defects (if you have an 1-bit-screen
- you will often have a lot of color-defects :-).
- It will also take some time to show with xv.
-
- You can produce nice overview prints if you get the icontact
- program of Mark B. Hanson and put something like
-
- decode pcd hpcdtoppm -1 -a
-
- in your ~/.icrc
-
- or by use of the pcdindex script of Pieter S. van der
- Meulen in this distribution.
-
-
- If you compile the program on a machine other than
- SPARC please send me a short email which machine
- you are using, whether you had problems or which
- changes you have made.
-
- If you port the program to any machine, please tell me,
- what you did and where to get the program. Within the
- last weeks i got a lot of mail asking for the special
- Amiga/NeXT/SGI/... version. Read the Special.* files.

-
- Thanks to
-
- - Adolf Mathias (mathias@ira.uka.de) for writing some of the
- postscript drivers.
-
- - Pieter S. van der Meulen for the contact sheet script.
-
- - Jeff for finding out how to detect the orientation of the
- Overview thumbnails [ Hi Jeff, how are you? :-) ]
-
- - A lot of people for sending mail about
- compilation on MS-DOS and OS/2 and many other machines.
-
- - lots and lots of people for sending me their improvements of the code.
- Sorry, but i can not read and analyze them all. I do not have so
- much time for the decoder, its my hobby, not my job. Often i get
- mail with a complete source and "Hi Hadmut, i have improved your
- code. It is now faster/smaller/better/something_else." But i don't
- know, *what* is changed. A simple diff doesn't work, they all were
- reformatting my source completely and i do not have the time to
- read all sources to find the real changes. There are a lot
- of real good ideas, but *please* tell me, where is the beef.
-
- - lots of people sending me just a formatted version of my code.
- Thanks to them all, and yes, i have indent(1). I prefer
- this way of formatting C-source.
