           Summary: Resize error when sharpening in image editor
           Product: digikam
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: rbr28 at yahoo.com


Version:           10.0 rc2 (using KDE 4.2.0)
OS:                Linux
Installed from:    Gentoo Packages

I've tried to narrow this down and the error is definitely reproducible on
different machines.  Here are the steps that will hopefully reproduce the
error.

Use a RAW image with a portrait orientation...the error does not seem to occur
as often with landscape orientation images, but I have had the error with all
images.
Choose to edit the image.
Choose Transform - Resize...use 25% for the resize (the resize value does not
seem to be important).
Then choose to Enhance - Sharpen, using Refocus.
In the new preview the image will be zoomed excessively...maybe 125%, maybe
175%.  This obviously is not useful for sharpening which should be your last
step in workflow.  Using the zoom out buttons, the image cannot be zoomed out
even to 100%.
This error does not occur 100% of the time, but it does occur very often.  I
have been able to work around it by zooming out on the original image to a low
value, before choosing to sharpen.  For example, if I zoom out to maybe just
25%, the zoomed value when I sharpen may only be 75% and I can actually then
zoom in on the preview to 100%.  At some point the image will always be
previewed above 100% in the sharpening preview, and it cannot be zoomed out to
a lower value.  I don't think this is the intended behavior.
