Cropping pages in PDF documents is an essential part of my workflow (as I suspect it is for many). I used to use Preview on OSX to do this, which was no problem.
I am running into a problem with this in Devonthink. If I open a document from Devonthink in Preview, then when I go to save it, it says that the original can’t be modified and that I must save a copy, which subsequently doesn’t appear in Devonthink. Obviously not a satisfactory solution. However, I also can’t find out how to crop a page from WITHIN Devonthink.
Thanks korm. I just tried that method. “Save” appeared to work, though when I went back into Devonthink the same uncropped version is there. Opening it again in Preview shows the cropped version. Ah, just a problem with the thumbnail I thought. Though updating the thumbnail changed nothing. I removed the thumbnail, then created it again, and still the uncropped version on the thumbnail. If I open in Devonthink however, it is the cropped version!
This is an Apple issue, not a DEVONtech one. Apple doesn’t allow Preview to edit files in the User Library, where the DEVONthink Personal library lives. That’s their call, not ours.
Your best bet is to crop before importing or upgrade to Pro / Pro Office and use separate databases located in a folder in your Home directory.
Indexed folders and documents show an upswept arrow icon to the right of the document name. I suspect that your documents are not Indexed, as indexed PDF documents are editable in Preview.app (no warning that the original document cannot be modified).
It depends what you are asking; records which reside in the global inbox cannot be edited using Preview, because Preview cannot save back to the global inbox. This issue was described further up, and remains unchanged. Other software - Adobe Acrobat, for example - does not suffer from that limitation, so can edit and save back to global inbox.
The default location for databases (other that the global inbox) in DT3 is not in the user library (but rather in the user directory). Preview does not suffer the same limitations here.
As such: you can edit records using external apps. Using Preview, you are limited to editing such records which are anywhere but in the global inbox.
In the meantime, DEVONthink’s ability to play nice with other software means that it doesn’t have to be able to do everything on its own (says the random user on the internet who keeps that behemoth Adobe Acrobat handy, and hates it’s guts.)
