Convert.exe is a simple DOS utility which converts the image in a
printer image file in HP PCL format from a positive to a negative
form. I wrote this utility to print negative PCB artwork directly
without the need for an intermediate photographic reversal step. I
use it primarily with artwork generated with DOS based Protel software
but it might work on graphics output from other software as well. I
don't think it will work with compressed graphics formats.

This software works only on graphics output produced for HP compatible
printers.

The procedure I use is as follows:

        *       Create the original image
        *       Send the output to file rather than printer
        *       Convert the file using my utility
        *       Print the converted file (using DOS print)

Usage:

        convert {source file} {destination file}

The source code file (convert.bas) is included. It is written in
Microsoft QuickBasic. Feel free to modify this file any way you wish.
For example, it should be easy to modify it to feed output directly
to a printer instead of a file.

This software is provided free of charge (except for any handling
or distribution charges which others might impose). Please note, however,
that I make no claims whatsoever either as to its suitability for any
pupose or that it is bug free.
