Re: [Therion] Semi-transparent rock borders

I have some closed rock borders that are opaque as expected when viewing my PDF file in Adobe Acrobat and FoxIT but are semi-transparent in Okular and Atril.

Any suggestions on how to make them really opaque (on all PDF viewers)?

Translucency (which you only get on rock borders when using "smooth-shading off"), does not work in all PDF viewers. There is nothing you can do about that, unless you are able to submit a code patch to the PDF viewer application. https://therion.speleo.sk/wiki/contrib:externalviewers Sorry, I know that's not what you wanted to hear.
