So I'm thinking this is nothing to do with the PDF document itself, but perhaps stems from a conflict between AAPro9Ext and another program installed on the same machine (i.e. If I close the PDF, but leave AAPro9Ext running, on re-opening the PDF, previously correct display of highlighting (and any additional highlighting performed) now blocks out the text (as per screen-cap p2 in shared example above).
I tried an installation of AAPro9Ext on a laptop, and this does not echo the problem: PDF documents which fail to display highlighting correctly on my PC 'perform' as they should on the laptop.Īs mentioned, on first opening AAPro9Ext and the above test file on my PC, the highlighter works/displays as it should. I've uploaded a test text-based PDF file, which includes (p2) a screen capture of the highlighter glitch as displayed during use. Hello daka360 (or can I just call you daka :-) ?) So I'm guessing there is some obscure glitch/switch which is seriously altering the behaviour of the program, which in the absence of some brainy/obsessive Acrobat 9 Pro user chasing their tail long enough to figure out the solution (and broadcasting the answer globally), Adobe itself should address with some urgency. However (!!), if the document is closed without closing the Reader program, and then re-opened in Reader, the existing highlighting obscures the text once more, and using the tool also obscures the text. If I closed the PDF without closing Acrobat Pro, on re-opening the document, the highlighter obscures the text.Ī commenting-enabled PDF, correctly highlighted in (a fresh-boot of) Acrobat Pro, saved, and then re-opened in Reader, shows correct highlighting, with the tool enabled and working correctly in Reader. I tried enabling these PDFs for commenting in the reader (Comments>Enable for commenting and Analysis in Adobe Reader.), but this doesn't appear to be any answer.However (!), I discovered that the highlighter would work properly if I closed the Acrobat program down and then opened the PDF(s) in a fresh boot of the program.
This would be an unacceptable alteration to the way the program works, but this effect did not appear to occur immediately after installing the update (to v9.2.0), and I am unaware of any more recent auto-update. I tried altering the opacity as suggested here, but that is an unacceptably crude remedy (no slight to lkassuba intended): as has been pointed out, reducing the opacity to around 25% results in an insipid yellow and the highlighted text looks partially erased. image with hidden OCR text layer), but on going back to check, using the tool completely obliterated the text (and/or the text image). A week or so ago the highlighter appeared to work just fine on an OCR-scanned-document PDF (i.e. I tried two different word-processors' test-piece pdf exports with same result. I found this thread after just now after using the highlighter on a word-processed PDF export, when the highlighter completely obliterated the text. Just discovered the same problem here: except that it seems to arise and disappear for some as yet unascertained reason (see below)! I cannot recommend this program to anyone because of the way that highlighting now works. If I use the yellow highlight tool, I can barely read the highlighted text. When the documents were created on AP9 weeks ago, they could be read. Documents created weeks ago cannot be read because the yellow highlighting completely obscures the text. If I open another document or close the program and return to a document, highlighting does not work as it once did. However, after the reinstall, highlighting works as it once did for one document only. Highlighting works as it once did if I uninstall and then reinstall the program. I can’t believe that faint and hard-to-read text is the intended result. It is also not the way the program should work. This is not the way that this program initially worked. The text can then be seen, but it is very faint and hard to read. To use the yellow highlight tool, opacity must now be set at 25%. With opacity set at 100%, which it always had been, the text is now completely hidden. Highlighting did not work as it once did. Within the last two weeks, I noticed a problem.
I had no trouble reading the black text “behind” the yellow highlight. Opacity was set at 100%, which is the default on my installation. I used the highlight text tool with no problem. I have been using Acrobat Pro 9 for several months.
I think I need to explain the problem in more detail.
