@cgrunenberg When using custom colors for highlighting, I noticed some weird behavior, outlined below.
My highlighting colors are adapted to Preview’s colors for higher consistency between apps. That’s why I use the following setup in DEVONthink:
The color values were picked with Color Slurp app (because they are correct and give the same highlight color result in Preview) and not with the Mac integrated color picker (because they are not correct and look different in Preview).
Now, when highlighting in DEVON, DEVON displays the color differently at first:
After closing that window and reopening the file within DEVON, it changes to the correct color value, FC5C88 in this case, as set in DEVON’s preferences:
Reopening a PDF and making some new highlights showcases that difference (first 3 lines are the correct color after reopening and lines 4–6 are the wrong color after adding more highlights and not having closed and reopened the PDF yet):
Opening this PDF in other apps tells us more. The side by side comparison shows Preview, PDF Viewer, PDF Expert and Highlights.
It can be seen that PDF Viewer (second from left) shows the same issue of 2 different colors, with line 4–6 being wrong (difference tested with color picker):
While closing and reopening the file in DEVON corrects the issue and the tested PDF apps (except PDF Viewer) can display the PDF file with the correct color instantly (irrespective of having closed and reopened the file within DEVON), PDF Viewer has some more peculiarities.
No matter what I do in DEVON, opening the PDF in PDF Viewer always keeps the last highlight in an incorrect color state. The following image shows lines 4–6 incorrectly. Having closed and reopened the PDF in DEVON doesn’t matter. Closing and reopening in PDF Viewer also doesn’t make a difference. Also notice the difference in highlight style rounding from line 4:
Now, adding a highlight in DEVON and then opening the file in PDF Viewer, fixes lines 4–6 in PDF Viewer, while line 7 (the last added highlight in DEVON) is now incorrect in PDF Viewer:
It doesn’t matter how the file is edited in DEVON, I can also use another color (yellow in the following image) or underline, the latest change in DEVON (yellow highlight) fixes the second last change (line 7) in PDF Viewer and keeps the last change (yellow highlight) in an incorrect state in PDF Viewer:
This applies to all colors, not just red.
Given that all other PDF apps I use don’t have that issue, it seems that DEVON uses the PDF engine provided by PDF Viewer, with a similar buggy highlighting behavior.
I’m ok with DEVON having the correct color after closing a file, but the last change fixes second last change behavior in PDF Viewer is wild.
