Print to PDF - Black background on transparent images
« on: January 21, 2021, 12:57:30 am »
Hi,

A bug impacting transparent images on diagrams has been there for a while now (tested with 15.2 last build).
For images, I found a workaround by using the publish menu to save the diagram image to a file -> the result is fine in the PNG file.
Unfortunately I cannot find any workaround for PDF files. Users are exporting to PDF as it supports text within element e.g. you can select and copy a class name.

Any idea to overcome this?

If they can select the classname, that means that the diagram is exported as a metafile, and not as an image.

And since metafiles don't support the transparency, I'm afraid there isn't much you can do.
