Screenshot of the issue

Hi,

I am running Slackware current64 and after the latest batch of updates I noticed the level tools output is a solid color. I tried changing settings but that only affects the color output (for example it turns gray)

I recompiled Digikam 2.5.0 but it didn't help. I compiled and installed digikam 2.6.0rc and I get the same behavior.

I'll add a few details, let me know what else should I provide. I'm at a loss even where to begin searching.
xorg-server-1.12.1, 64 bit slackware current, kernel 3.2.13, i7 quad core cpu, 16gb of ram

No reproducible here under Mageia Linux or MacosX or Windows. Levels Tool work perfectly with 2.6.0RC release.

Sound like a SlackWare version, probably with Qt4 library which is used to display preview effects.

Due to a known bug in current git, for all color channels the input interval is reset to 0..0
Matthias is working on a fix (or is it already fixed? Matthias if you dont have time we must revert the initial patch before 2.6 final)

Thank you for the answers. Still I suspect there is another issue here as well because 2.5 used to work fine for me until some package upgrades (x related, I'm sorry I don't know for sure which, but I'm sure no updates to QT or KDE) Now, even after recompiling neither 2.5 neither 2.6rc works for me.

Add kconf_update script to prevent black image in adjustlevels

This update script reverts adjustlevels configuration to the default
by removing the respective config group from digikamrc. It prevents
showing a black image in adjustlevels tool after updating to 2.6.0

Thank you,

It must have been triggered by testing 2.6 and not slackware upgrades. Anyways I removed [adjustlevels Tool]

from ~/.kde/share/config/digikamrc and now the levels tool behaves again.
