Hi all,
when generating batch pdf with Atlas, if a map has an overview frame set with transparent fill, then pdf are corrupted.
With adobe reader, opening pdf is impossible (raise error 14). Foxit reader opens pdf but overview frame are no more transparent.

I found a workaround with setting no fill in overview frame style, but it is a caveat since default style has a fill and generates corrupted pdfs.

New tests, and we again have an inconsistent behaviour... In other situations, overview frame have nothing to do with pdf export problems..
I keep on testing.

a new clue: Problem only affects vector export.

Does it work ok without atlas generation ?

I've just produced a pdf with an atlas from a vector layer and with a transparent overview, and it works fine with Evince (Linux) and Adobe reader 10.1.14 under Windows. The pdf has been generated from a Linux version of QGIS.
Can you add here the corrupted pdf you obtain (there might be differences in the way pdf are generated by Qt under Windows) ?

Hi Hugo,
I've never reproduced this problem outside Atlas use-case. Please find attached a corrupted pdf. I use Adobe reader 9.5.2 and Foxit Windows XP 32 bits.
Hope it helps

Ok, I can reproduce the problem. Adobe reader gets an error. xpdf on linux crashes.
The overview frame with evince is not transparent.

I suggest to look also at Bug #6741, that I opened about a month ago.
Good bye

  • Priority changed from High to Normal

Same problem with labels here, when labels have transparent background.

Note that the first exported file (the PDF corresponding to the first feature) is exported well...

Here's a bugfix :


I'm a newbie in C++ programming, and my fix doesn't seem very elegant to me... It would be nice if someone could confirm if it's acceptable.
