Description S. Burmeister 2010-03-17 01:40:52 UTC 
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.

Comment 5 S. Burmeister 2010-03-17 08:53:08 UTC 
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!
