We used have Qt 4.4 and when we printed to PDF-file, it was very quick and filesize of PDF was something like 44kb. Now after we moved to Qt 4.7, PDF-size is < 1 MB. Its seems like it is printing pictures and it is not using vector. Any idea?
In my application create pdf with qt 4.5 4.6 4.7 have no difference.
Nor have I seen such big difference, can you post some test program here that can reproduce your problem
