Standalone Beta: PDF reader displays transparent freehand drawings with full opacity

jhimmelreich · February 8, 2022

5.0.97-beta.65+15ae72d14

The integrated PDF reader seems to display freehand annotations that have an opacity <1 without any transparency. I use freehand drawing in PDFs to highlight.

Happy to share the PDF via email if it helps

Sure, you can send it to support@zotero.org, with a link to this thread.

What software was used to create those drawings?

Just sent it.

I used PDF Viewer for some of them, and — I think — an old version of GoodReader for others.

Having the same problem with highlights created in Papership on an iPad. Let me know if an additional example of these would be helpful.

I can also confirm this problem, using PDF-Exchange Editor. I only noticed it after trying to import all annotations: freehand annotations that where transparent now cover the text completely making it unreadable. But I don't know if the problem was already there before I did the import, I mean when only reading them in the native pdf reader.
