Is it really true that Crystal Reports does not support images that have transparency?
We are using it at work and the guy that does Crystal Reports told me it does
CR doesn't support transparency but you can use a wmf image to solve your problem. I'm using CR 12 (2008), i need to put an image as signature (as a watermark) on another image.
Example:
Background_image.jpg Signature_image.jpg
Convert Signature_image.jpg into a wmf file using "Inkscape" (freeware).
In the report, we have "Background_image.jpg" and over it the "Signature_image.wmf" image, it works great!
