[Bug 231048] New: monochrome tool shows plain grey preview

[S. Burmeister]

https://bugs.kde.org/show_bug.cgi?id=231048

           Summary: monochrome tool shows plain grey preview
           Product: digikam
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           Rev: 1104118 (using KDE 4.4.1)
OS:                Linux
Installed from:    openSUSE RPMs

If I open the monochrome tool and enable the preview, e.g. the lower half of
the image should show the preview, then that area is just plain grey and the
shows "target".

Applying the tool does generate a plain grey picture. So the preview is right
when it shows plain grey. :)

The small preview in the thumbnailbar within the tool does however show the
picture with the different types of monochrome "colouring".

It a problem related to the initialisation of parameters, look into the last
tab, the contrast is set to zero, that is why you get a plan grey picture.

Gilles is aware of the problem, I think ?

Maybe this bug has already been solved and it affects only user who have been
using some svn versions which put a wrong contrast parameter ? I think a quick
fix for you would be to try another contrast setting.

You are right! The contrast was set to 0. Resetting it to the default solves
the issue and restarting digikam keeps that default.

Thanks for the hint!
