Saving Images ...

[Tom]

I have a Metafile that I would like to save as an image. So far, this seems
to work fine:

Metafile x = new Metafile(myFile name);
x.Save(jpgFilen ame, ImageFormat.Jpe g);

While I get the image fine, the background is black. For the life of me, I
can't figure out how to make the background white. Any ideas?

Somebody please make me feel stupid. Thanks.

Black is the color of default-initialized pixels (0 for all components).
You have two options: modify the metafile so that it explicitly fills a
white background behind itself, or draw the metafile into a Bitmap
instance you've cleared to white and save the Bitmap instead of the
metafile.

Thank you Pete. I'm up for either of those 2 options (probably prefer the
Bitmap), but I can't find any example code anywhere to get me started. How
would I draw the Metafile object into a Bitmap object that has been cleared
to a white background?

Thanks again.

See the Graphics and Bitmap classes. In particular, create your
destination Bitmap, call Graphics.FromIm age(), then draw whatever you want
with that Graphics instance (see Graphics.Clear( ) and Graphics.DrawIm age()
for inspiration).

Don't forget to dispose your IDisposables. :)

Thanks again Pete. I'll check it out.
