Hello, I'm trying to compose a pcx file class for my own use in another 
program I am writing and am having limited success.  When reading in a 
very simple pcx file (test.pcx) and then display it in mode 13h it work 
fine.  When I try a more complicated example (image.pcx) which will be used 
when the full application is completed (a program to generate fourier
transforms of different apperature, read in from the pcx files) but the image
is scretched and obscured.

You can get the source from http://neutrino.phys.laurentian.ca/~trobb/pcx.zip
or http://www.geocities.com/SiliconValley/Vista/7489/pcx.zip
The problem pcx file is image.pcx  Here is some of my diagnostic output 
(rle decompression removed).

Start                                   : 0
After header                            : 128
Offset                     	        : 9200
After data                              : 6264
After fseek(fp, -786L, SEEK_END)        : 6269 <- see note 
After palette                           : 7037
After fseek(fp, 0L, SEEK_END)           : 7037
feof                                    : 0

Note:
  One question is what are those missing 5 bytes for?

When you run driver you'll see the two images displayed, which should 
both be the same thing.  The upper is the buffer which the pcx file was 
decompressed to (too be removed after the class is completed) and the second 
is with a overloaded operator[] the buffer is copied to.

Any help will be apprecieted.
