           Summary: DPI-information in files NOT used when printing
           Product: showfoto
           Version: unspecified
          Platform: Mandriva RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: maxantispam freenet de

Version:           0.3.1 (using KDE KDE 3.4.2)
Installed from:    Mandriva RPMs

Graphics-file formats like PNG, JPG, TIFF, etc. are able to hold the DPI-information from a picture.

Therefore it should be possible in an easy way to do a 1:1 printout.

To test this I've made a sample PNG-file which should be printed in size 15cm x 20cm.
I added black border lines to be able to check the printout-size with a simple ruler.

DPI--Resolution stored in graphics-file: 300dpi
Width: 1.772 Pixel => 15,0cm (5,91")
Lenth: 2.362 Pixel => 20,0cm (7,87")

With ShowFoto / ImageEditor it is impossible to use this DPI-information stored in the graphics-file for print-outs:

Print-option "Automatic scale":  Picture will be re-sized to fit in page.
Print-option "Print exact size": Size of picture has to be MANUALLY typed in.

There is no possibility to have automatic 1:1 printouts (or scaled printouts, i.e. 50%/200%, etc.) in ShowFoto / ImageEditor!
