PDF text recognised in Preview but not Zotero
I've scanned some documents onto my computer using DeskScan. The saved pdf files have text that is recognisable and I can highlight in Preview on my Mac. However, the file does not seem to have text recognised in Zotero either on Mac or iOS. Any idea what the issue might be?
We suggest using the “Area” annotation tool to draw a rectangle around the desired lines.
For example, a Japanese file OCRed in Acrobat is often highlightable in readers other than Zotero.
OCRed first line from https://www.maff.go.jp/primaff/kanko/nosoken/attach/pdf/195904_nsk13_2_09.pdf:
Zotero is grabbing text from a completely different part of the page, and doesn't highlight the text to show what's being selected.
This has always been the case with the v. 6+ PDF viewer, and is consistent behavior across files.
This is a major issue for those of us who work with vertical text, of course, and it would be wonderful if a fix could be found.
I created a short screen recording (under 20sec) showing a typical example of how, in many vertical-text documents:
1. Highlights don't show for both text selection and annotation
2. Selected and annotated text don't match
As always, highlighting this file works fine in standalone PDF readers such as Acrobat, Skim, Preview, etc.
Here is what you see:
* 00:00-00:10 I select and highlight the text
* 00:11-00:17 I click on the annotation in the sidebar, illustrating two things: 1) the highlight is still invisible, and 2) the annotation does not match the selected text
Don't know if it's helpful, but in Japanese, articles tend to be horizontal, while books are more often vertical.
