Description Gerhard Kulzer 2007-05-28 14:34:54 UTC 
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...

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, this entry still always valid ?

Comment 4 Gerhard Kulzer 2008-03-21 21:33:34 UTC 
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.
