Just to refresh people's memories, the original query was for an inverse (white on black) viewing mode which is helpful for certain visual impairments and other situations where a light background can create excessive illumination (in case you ever need to view a PDF file during a blackout!). > George had suggested I contact the author of Xpdf --- a > program I was not aware of.

Ghostscript has a ps2pdf script which uses the 'pdfwrite' device. The pdfwrite device has been improving rapidly, so you want to use a recent version of ghostscript (7.04), but if the PS were created files with TeX and dvips, there is a bug that was only recently fixed in dvips (http://tomas.rokicki.com/gpatch.diff) that can produce incorrect glyphs when using Adobe fonts and the '-G' option in dvips. I highly recommend using the README file accompanying testflow.tex: CTAN:tex-archive/macros/latex/contrib/supported/IEEEtran/testflow/ to make sure your (La)TeX, dvips, and ps2pdf are configured properly, but of couse this won't help if you download a PS file created with an older version of dvips. > Finally --- thanks to all the people of the Free software community > for their unfailing courtesy, patience and willingness to help those > who need help. > > Kalyan It is nice to hear that things worked out well. -- George White <[EMAIL PROTECTED]> Halifax, Nova Scotia
