           Summary: Output resolution of print wizard is very low
           Product: kipiplugins
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: printwizard
        AssignedTo: kde-imaging kde org
        ReportedBy: d.h.j.takken phys uu nl


Version:           0.1.0-rc1 (using KDE KDE 3.5.1)
Installed from:    Gentoo Packages
OS:                Linux

I would like to report a problem that looks similar to the low-resolution printing problems reported before. If my understanding of the existing reports is correct, these problems have been solved some time ago. Now using Kipi plugins version 0.1.0_rc1 I see a similar problem. It looks like my problem has a difference cause though, because the wizard seems to be responsible for the downscaling, not the print system (see description below). If it turns out to be the same problem after all, one of the existing bugreports can be re-opened.

Description of the problem:

It looks like the print wizard uses a very low image resolution internally. When you use the 'small thumbnails' template and advance to the cropping settings, you can clearly see that each thumbnail has a resolution of only about 100x150 pixels. As the pixels are really big on the screen, it looks like the photos are being downscaled by the printing wizard itself.

When you actually print the thumbnail sheet, you get a printout with the same low resolution. You can clearly see that each thumbnail on the paper has the same estimated 100x150 pixel resolution as the print wizard shows in the cropping step. When you create a printing preview or save to Postscript you can also see the low resolution.

When using a printing template with a larger photo size (like four photos on one sheet ) the resolution is also very low.
