I'm running into issues with Preview on 10.10.2 and annotation opacities. Preview seems to not honor opacities set by other programs, and clears all annotation opacities in a file when saving a new version.
Specifically, I'm using PDFs that have been previously annotated with another program (Foxit PDF reader in Windows, or Adobe Reader on Mac) to have 40% opacity at a given color. When viewed in Preview, these annotation are displayed at 100% opacity (completely opaque) and are thus much darker in color). When I make a new annotation in Preview and save the edited file, it resets all opacity values to 100%.
Is there any way to get Preview to honor these opacity values, or at the very least not clear them when saving a file? I don't want to have to switch to using Adobe Reader on the Mac (which does display opacities correctly), but I may have to.
