GDI + 's drawimage doesn't work when printed

sweetsheng

On paper over 5 meters, drawimage graphics cannot be printed after 3.3 meters, and the first 3 meters can be printed. But drawrectangle is fine.

Obviously, because it exceeds the maximum value that the 16-bit variable can represent, changing the coordinate mapping method of Graphics may solve the problem.

But preview is no problem, drawRectangle can also be printed.

It's no use changing it, is it a defect of mfc? Wonder why dmpaperlength is made short.

No problem printing bitmap, but not metafile

This should be a design issue of GDI
You can change a mapping mode, for example, use one thousandth of a meter as the unit, then print more than 30 meters of paper.

I tried it, but it didn't work. The raster images are all right, but the vector image MetaFile does not work.

attention.

Forget dynamic paging.
