           Summary: Sharpen slider enhancement refresh previews continuously
           Product: digikam
           Version: 0.9.4-beta5
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Image Editor
        AssignedTo: digikam-devel kde org
        ReportedBy: msp debian org


Version:           0.9.4-beta5 (using 3.5.9, Debian Package 4:3.5.9.dfsg.1-4 (lenny/sid))
Compiler:          Target: powerpc-linux-gnu
OS:                Linux (ppc) release 2.6.18-5-powerpc

This is a forwarded report from:

http://bugs.debian.org/433116

I confirm this is still an issue with 0.9.4-beta5.

A better explanation of this issue, is that when using the Sharpen slider, the sharpen transformation is started before the slider is released.

Thus it is impossible to drag the slider slowly from one extreme to the other slowly, as it commences the transform before the slider is released.  The user then needs to await the completion of the transform ( a couple of seconds at least) until one can continue sliding.

Package: digikam
Version: 2:0.9.2-3
Severity: normal

Hello,

some plugins (eg. sharpen) refresh the preview continuously. This is
bad, because it makes the UI almost unusable. For example, buttons
become disabled and then reenabled every 1/2 seconds, which makes it
very hard, if not impossible, to click on them.

Regards
