Metafile to BMP (or image type) need to retain quality

Hey All,

I have a metafile that I want to convert to an image format. The main
purpose behind this is to rotate the image 180 degrees. However, the
quality is quite pixilated. What is the best way to do this?

basically I want to convert the metafile to an image format, rotate
180 then print it.

The metafile is generated from
Microsoft.Reporting.WinForms.LocalReport.Rendor (Visual Studio
reportviewer).

If I print it out directly without converting to image the quality is
there.

Thanks for any help

One way is to not convert the metafile at all.  Use 
Graphics.RotateTransform(180.0F) while printing your metafile.

I would be willing to bet money that you are using the printer DC 
settings to determine the resolution of the image. Remember that this is 
given in 10ths of an inch NOT in pixels. To obtain the correct image 
size for your printable bitmap you should multiply the declared size by 
the DPI/10 of that dimension.

Remember also that not all printers have square pixels so you may need 
to create an image with a different horizontal resolution to vertical 
resolution.

Thanks guys for the help! Yes, I was just following MS examples and
was rendering to a metafile instead of a BMP. If I render to a BMP
then I just rotate and all is good. Sometimes I make things too hard.
