Hi,
I use Printer.Canvas.StretchDraw and I get my Bitmap UpSide-Down. What
is the option to correctly rotate picture ?

There is no standard procedure to rotate images, you can use something
like this:

AFAIK, PalcalMagick also does this:

I found that when I set negative height (-Bitmap.Height) in
StretchDraw then it is ok.
