Replace scaling with SetWorldTransform?

[CodeBrain]

I have an application that prints the contents of the screen on a printer. The user has the option to select some scaling factors for the print out. (E.g. fit to page, etc...) I am using the same printing function, which draws in a DC for the screen output and for the printer output. On NT, 2000 and XP am using the SetWorldTransform function before painting to the printer DC in order to scale the output. This works fine. But since SetWorldTransform does not work on 95/98 or ME, I am searching for a replacement of the SetWorldTransform function. Of course I only need the scaling ability of the SetWorldTransform function with constant factors for x an y. I am painting in the MM_TEXT mode so I thought that I could use the MM_ISOTROPIC instead to scale the viewport extends. So I need the same features (coordinate directions, origin) like in MM_TEXT mode but with scaled viewport extends!? How can I do that (SetWindowExt, SetViewportExt,...)? I already tried some things but without any results. Thanks in advance.

In a past project, I used MM_TEXT for screen drawing and MM_ANISOTROPIC for scaled printer output. Worked fine.  onwards and upwards...

Yes, I think that is a good way to do it. I have found a good article about the mapping topic. http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/dnargdi/html/msdn_mapping.asp The description is more detailed then in the API/MFC documentation.
