- README-file for Photo-CD software for DOS and OS/2
- Version 1.5
- (c) 1993/94 by Holger Hinze
-
- PCD.EXE is a simple program for showing your Photo-CD pictures in OS/2
- fullscreen sessions or under DOS (only 386 or higher).
-
- PCD15.ZIP contains the following files:
- --------------------------------------
- README.PCD
- PCD.EXE
-
- only needed for OS/2:
- EMX.DLL
- EMXIO.DLL
- VESA_ET4.DLL
- VESA_TR8.DLL
- PCD.ICO
-
- only needed for DOS:
- EMX.EXE
-
-
-
-
- The following configuration is needed for running it under DOS:
- ==============================================================
-
- DOS (no DOS session of OS/2)
- CD-ROM drive
- EMX.EXE
- 386-processor (or higher)
- VESA bios extension for your graphics card (if not supported directly
- from your cards bios)
-
-
-
- The following configuration is needed for running it under OS/2:
- ===============================================================
-
- OS/2 2.x
- CD-ROM drive
- Vesa-fullscreendriver VESA_xxx.DLL (see note below)
- emx-DLLs EMX.DLL and EMXIO.DLL (version 0.8h or higher)
-
- You should move VESA_xxx.DLL, EMX.DLL and EMXIO.DLL to a directory mentioned
- somewhere in your LIBPATH.
-
-
-
-
- VESA_xxx.DLL (only for OS/2):
- ============================
- If you have a ET4000 or Trident 8900 based graphics adapter, you can use one of the
- included files VESA_ET4.DLL or VESA_TR8.DLL. These DLLs support only 256 colormodes.
- For ET4000 hicolor cards or other cards look for the Vesa-package VESA15.ZIP from
- Johannes Martin. It contains a ET4000 hicolordriver and information how to generate
- drivers for other cards. (The presentation-manager-driver included there does not
- work with this program!).
-
- If you don't use VESA_ET4.DLL, you must set the environment-variable VESADLL to the
- VESA-driver you use.
-
- e.g. SET VESADLL=VESA_TR8
-
-
-
- How to start the program:
- =========================
-
- The simplest way to run PCD.EXE is starting it without any parameter.
- The program will then ask you for the following parameters:
-
- - number of the first picture to show. The number of picture is extended
- by the program to the filename IMGxxxx.PCD, where xxxx is the
- number of the picture.
- - resolution of the picture. Only the 3 lower resolutions available
- on Photo-CD are possible: 768x512, 384x256, 192x128 pixel.
- - which mode to show the pictures. You can show it either in 256 color,
- in 32768 color, as grayscale or extract one of the 3 basic colors red, green or blue.
-
- You can add one or more of the following parameters. In this case it
- doesn't ask you for the missing parameters and uses defaultvalues instead of.
-
- HICOL use hicolormode
- BW show as grayscale
- (RGB is default)
- HIRES show with resolution 768x512 (default)
- MEDRES show with resolution 384x256
- LORES show with resolution 192x128
- n number of the first picture to show (default is 1)
- filename path and filename of a picture to show
- (only filenames of the type IMGnnnn.PCD are allowed,
- PCDPATH will not be added to the filename)
-
- e.g. PCD.EXE 5 HICOL shows IMG0005.PCD in high resolution and hicolor.
-
-
- After loading the first picture the program will show you the picture number
- in the right bottom corner of the screen. (only in graphicmodes with at least
- 800x600 pixel)
- You can change to the next/previous picture by using the keys -> and <- .
- While showing a picture the program tries to load the next one. So, if you
- change to the next picture by pressing -> ,you normally don't have to wait
- until the picture has been loaded.
-
- You also can change to an other picture by typing the number directly
- (up to 3 decimals). In this case the keys you have pressed are shown
- left to the picturenumber. These numbers are shown in green, if the picture
- can be loaded, and in red, if there are problems (e.g. picture doesn't exist).
-
- To exit the program press the <esc>-key.
-
-
- You can set the following environment variables for running the program correctly:
-
- PCDPATH You can specify the path to search for your pictures.
- e.g. SET PCDPATH=C:\PCD\MY_IMAGES\ (must end with '\')
-
- If PCDPATH is not defined, the program tries to find a drive
- containing the directory \PHOTO_CD\IMAGES\
-
-
- PCDRGBVIO Specifies the VESA mode for 256-color and grayscalepictures.
- You can use any 256 colormode.
- e.g. SET PCDRGBVIO=19 in decimal
- SET PCDRGBVIO=0x13 in hex
-
- possible modes are:
- 0x013 320x200
- 0x101 640x480
- 0x103 800x600 (default)
- 0x105 1024x768
-
-
- PCDHIVIO Specifies the VESA mode for hicolorpictures.
- You can use any 32k Hicolormode.
- e.g. SET PCDHIVIO=272 in decimal
- SET PCDHIVIO=0x110 in hex
-
- possible modes are:
- 0x10d 320x200
- 0x110 640x480
- 0x113 800x600 (default)
- 0x116 1024x768
