pcdview
=======

1) Introduction

This is a svgalib-viewer for PhotoCD-images. pcdview displays
the 768x512-resolution with the 800x600 graphics mode. If it
finds a hicolor-mode (32k colors), the image will be displayed
with colors. The 256-color-mode will display a grayscaled
image.

2) Usage

Simply call pcdview with the filename(s) of the image(s), you
want to see. pcdview loads and displays all the images.
By default pcdview waits for a keypress, and then displays the
next image.

3) Options

-d >time< pcdview doen'nt wait for a keypress between the images,
          but sleeps >time< seconds before displayinf the next
          image.
-e        pcdview enters an endless loop. Only useful for more
          than one image. If the last image has been displayed,
          pcdview starts again with the first one.
-g        forces to use the 256-color-mode with grayscaled
          images. May be useful becauce the decoding of grayscaled
          images is very fast (less than half the time for a
          colored image. Ok, only when loading the image from
          buffer cache instead from CD-ROM. When loading from
          CD, the grayscaled image needs around 70% compared
          with a colored image with my doublespin CDROM)

4) Other informations

pcdview does'nt take care about the orientation of the image.
Images are always displayes as landscape. You have to turn
your head for portrait images ;-)

Truecolor is'nt supported. It's because I can't test it myself.
There are some pieces of code and some comments for truecolor,
it should'nt be to hard to implement it if someone realy needs
it. (Sorry, some source code comments are in german language).

pcdview is freeware. You can do with it and the source-code
whatever you want...


have fun !
