COMPATIBILITY OF XCHANGE VIEWER PDF FILES WITH MAC SOFTWARE

[leo.quigley]

As a graduate student I’ve been using pdf-XChange viewer happilyfor several years for highlighting areas of text in articles my school supplies as pdf files, or in articles I have scanned in. Some of the articles are images rather than actual text, but this is not a problem in XChange viewer because you can simply overlay a yellow rectangle and use the ‘multiply’ setting and still see the text behind the highlighting.

Now I am needing to read these files regularly on a Macbook Pro. Sadly, there is no version of XChange Viewer for Mac yet, but I had expected the pdf files would be compatible? However, two odd things are happening in both Preview and Adobe Reader on the Mac when I try and view pdfs I have highlighted with XChange Viewer– firstly, the text image is overflowing at the bottom of some pages, and secondly the yellow rectangles are completely obscuring the text! I can edit the rectangles one at a time to make them more transparent, but I have dozens of highlighted comments in each of hundreds of articles, so going through every comment one at a time would take months. I can’t find a ‘multiply’ function in Adobe Reader in the way that XChange viewer implements it, and I don’t know what to do about the overflowing text.

The odd thing is that I can view my articles OK on Adobe Reader in Windows, where the highlighting effect shows correctly and the text fits the page just as in XChange viewer.

Any suggestions what might be the problem and whether there is a workaround for viewing XChange-created pdfs on a Mac?

Many thanks.

Hello leo.quigley,

The Annotations we create (and with Blending mode) do conform to the PDF specification - but it seems like this works differently on Macs. The easiest solution I could think of is to try out programs like "Parallels" that allow you to install Windows soft - and then just continue using our Viewer.
I'd also recommend you to try out the new Editor:

Which succeeds the Viewer and is much better than it in pretty much all aspects

Regards,
Stefan
