I wrote a simple program that plots Gerber RS-274X files to a TIFF at
any specified resolution. There is an option to make negatives. I
haven't supported all the features of the RS-274X standard but it should
work fine with Protel. If you have any questions then feel free to
contact me. There is a lot more work needed to turn it into a useful
tool. note: GERB2TIF is a Win32 console app.
