PDF compatibility - Page 2

How about a sticky about PDFs that don't work? At the moment I don't have a special one in mind, but I can imagine there will be more in the future...

Well, after all it seems that these additional images (smaller resolution and with the interpolate flag set to true) weren't at fault: I found a way to delete them all through preflight fixups, but the resulting file still couldn't be read by the M92.

I further discovered that this file displays fine if you choose a zoom level of 100% or 125% (quite small, covering less than half the screen), but as soon as it is 150% or more (or fit screen), the page is white ...

Still not sure what exactly the issue is, as soon as I have time, I will try and fiddle with the OCR and other parts of the file layout. It seems related to how the file is rendered at different zoom levels, but it would be nice to know if the m92 or the file is to blame ...

After some more tests, it seems likely that the m92's pdf reader has a problem with transparency in this pdf (this seems the way scanned image and ocr are integrated in this case) - is anyone able to confirm this?
