Subject: Re: Conversion from WMF to BMP

Hi Warren,

I have done a quick test in the Demo.Dpr project, and the entire image is saved as an EMF file. Are you somehow using transparent images? Could you be doing a rotation and the corners have a background added?

If you have a minimal project that shows this behavior could you please email it to me.

Best regards,

Michel
