How to set rv contents transparent when print to DC / WMF

[lwinter]

We are using the RichView editor to paint its contents into a device context / metafile which in turn is placed into a diagram. The diagram can have a gradient background, but the contents printed into the metafile do always have their own background.

We need to be able to print transparent RichView contents to metafile.

Q:
How can RichView contents be made transparent when printing / painting to device contexts / metafiles?

Thanks for your help!
