Why QPrinter always generates PDF docs with the same size?

I don't understand this.

But nevermind, my real problem is that, with or without a printer driver, if i try to paint an image with QPainter under a QPrinter, the resulting doc has a big size

I would like to know if there's some other way to convert a succesion of images into a PDF doc?

Well, I add a new post but I don't know if anyone can help me

. I've installed Adobe Acrobat Reader 7.0 and has an option that allows working with the images of a PDF document. If I open the document created with Qt, the option is disabled. Otherwise, if I open another doc not created with Qt where the images are compressed, the option is enabled and allows extract the images of the doc. Maybe the problem is the driver that I use (PDfCreator). Anyone knows if there's some way to generate docs with QPrinter where the images are compressed? Can anyone check if, using Qt, can generate docs where the images are compressed using the code that I've posted above or some other way?

It might be a good idea to take a look at the source code responsible for generating images in pdf files in Qt4. The answer for your problem may be there. If that doesn't help, writing to Trolltech is an option too. I doubt we'll be able to help much here...

If anybody is interested, I have asked my problem in Qt Interest mailing list, and the response from a trolltech's member is the following:

The problem is not compression but the fact that the image is embedded
multiple times, even though it is the same. You can either wait until Qt
4.1.3, which will contain a fix for that, or you can try the current
snapshots which should have it, too.

So, finally seems that's just a bug... Does anybody knows how much should I have to wait until the next release?

You can always use a snapshot as suggested.

Yes but I'm a little lazy to build it all (> 2hrs)

Finally the Trolls have opened a new task tracker with my bug (ID: 111669): http://www.trolltech.com/developer/t...9&method=entry.
I hope it will be fixed soon.
