Check Convert Images to Monochrome with GdiPlus X

>
>I am trying to set up VFP 8.0 SP1 to send Black/White Monochome Images over to an Epson TM-6000II register printer (the image to print at the top of the register tape receipt before the items listed).
>
>I want to add to the POS sale program a menu option to allow the user to bring up a form that allows the user to pick any BitMap image, resize it to the appropriate size for the register tape, then conver it to Black-White Monchrome.
>
>I'd like to call a DOS program that would do the graphic conversion (so as to simplify setup for the user and us).
>
>Anything out there you use? I looked at ImageMagick, but it is a window based program, and would require us to have the install program install it (haven't tried that yet, but a pure DOS program would make it easier).

>I dunno.... what have you used and how hard was it to install ??
