- Documentation of pcd.datatype 44.3
- ----------------------------------
-
-
- Introduction
- ------------
-
- With the help of the pcd.datatype, your datatype sytem is able to read images
- from Photo-CD's.
-
- This datatype is freeware and can be used for any purpose.
-
-
- Minumum requirements for pcd.datatype
- -------------------------------------
-
- * OS 3.5
- * A mounted PIPE: handler !!
- * ixemul.library V39.
- * Lots of stack for the decode tool !!!
-
-
- Minumum requirements for PCDPrefs
- ---------------------------------
-
- * OS 3.5
- * MUI 3.8
-
-
- Installation
- ------------
-
- Simply click on the 'Install' script.
- As the pcd.datatype needs an external decoder, you must select a directory that
- is in your path to store the decoder !
- The installer will not check your configuration !
- You MUST store the decoder 'pcdtoppm' somewhere in your path, otherwise the datatype
- will hang up in an endless loop !!
-
-
- How does the pcd.datatype work ?
- ---------------------------------
-
- The pcd.datatype is to small to be a standalone decoder.
- Whenever the superclass detects a PCD image, it opens the pcd.datatype.
- This launches the external PCD decoder 'pcdtoppm', which redirects its output
- to the PIPE-handler. The datatype simply reads the decoded RGB values from the
- PIPE handler and stores them in the bitmap.
-
-
- Preferences
- -----------
-
- Resolution:
- The PCD decoder is able to decompress a PCD image to different resolutions.
- The default is 768*512.
- The two highest resolutions don't make much sense as you need a fast CPU
- and lots of memory !
-
- Currently I only support MUI for the preferences.
- If you don't have MUI, you also can adjust the preferences very easy.
- The ENV-variable 'DataTypes/pcd.prefs' contains the parameter as a DOS-argument
- with the template 'RESOLUTION/A/N'.
- You can change the settings anytime either by using the 'SetEnv'-command or by
- using a text editor.
