           Summary: Mixer does not work for green and blue selected as main
                    channel and monochrome mode
           Product: digikamimageplugins
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Channel Mixer
        AssignedTo: digikam-devel kde org
        ReportedBy: gerhardk gmx ch


Version:           0.9.2-beta2 (using KDE KDE 3.5.7)
OS:                Linux

The plugin works well when Red is selected as main color channel.
When green or blue is selected as main channel AND monochrome mode, nothing happens when changing the slider values.

Gerhard,

It's not reproductible here. When you set on "monochrome", the Red channel is selected automaticly and you cannot choose another channel. In fact Red channel adjustments are used to modify the luminosity of B&W picture.

Give me more information to try to reproduce this problem...

Gilles

Well I tried to put green as main channel, because Declencheur
(decl-2007-01-29.mp3) has an example application with Photoshop...

But I agree that the red channel should be the default main channel in a
monochrome setting.

You actually can select green and blue as main channel when monochrome was
previously selected and saved. Only when you go back to the default settings
per default button and then activate monochrome, only then green and blue are
unavailable.

So, I understand this is not a bug, but a feature (to use M$ lingo). But then
green and blue should always be disabled when monochrome is checked.

Gerhard

Well, it is solved now in the sense that:
whenever you activate green or blue channel as main channel and then select monochrome, red is being forced as main channel. Only 'monochrome' restricts the channel color setting to red.

That is a solution good enough. It does not allow blue or green to be main channels in monochrome conversions, but that is also not something one would need in practice.

I close the bug.
