I'm not really sure if GPIMAGE2 can save in MONOCHROME bitmaps.
But I'm sure that GdiPlusX can convert it.
Even not having VFP9, you can still download the GdiPlusX sources, and open the file "System.Drawing.Prg"
Look for the keyword "Monochrome", and there you'll find the source code that I used in that function, and adapt it in GPIMAGE2

A faster way would be to use Anatoly Mogilevets' solution, from www.news2news.com
