Creating Device Context

[Larry J Siddens]

Question: Can a Device Context be created by hand for a imaginary device? Reason: I am creating an application that will be outputting (drawing) to an image device that does not have a physical Device (like a printer). I would like to create this DC so that when I do calls like: LPtoDP or DPtoLP or even doing a line MoveTo( DC, point) and a line LineTo( DC, point) that I don't have to calculate the difference. In a 1200 dpi printer, and you want to draw a 1" x 1" rectangle you create the rectange (based upon your mapping mode, in this case we will use LOENGLISH) Rect( 100, 100, 200, 200 ) -> 1x1 rectangle starting at 1 inch from the top and left. So in a 1200 dpi this converts to 1200, 1200, 2400, 2400 in the actual drawing. I would like to be able to create a dc that does not connect to a physical device with a dpi say 350x350. How can this be done? AND, can it be done? Thanks Larry Larry J. Siddens Cornerstone Communications TAME THE DOCUMENT MONSTER www.unifier.biz

I believe what you want is a metafile DC. If you are using MFC have a look at CMetaFileDC. I have never used it myself, so I may be totally off base here.
