I've noticed that the Method e.Graphics.DrawImage when performing a printing is not behaving correctly when units are set to mm:
e.Graphics.PageUnit = GraphicsUnit.Millimeter; //e comes from the printer event handler "PrintPageEventArgs e"
I don't exactly know what unit is using exactly or whether there is a bad transformation of the units but the location of the objects and dimensions of the picture is not correct. In my test case I'm using the following function header:
e.Graphics.DrawImage(Bitmap, RectangleF(), RectangleF(), GraphicsUnit.Pixel);
Thank you very much in advance for this great team.
I've been doing some more testing, and having the very same page format (A4, graph units in mm) and the very same content, using different available headers for DrawImage() leads to very different layouts. Running the very same code in Visual Studio, the layout is perfect, no matter what function header is used.
This error still persists in the most recent version of Mono (updated from the Mono-Project sources)
