getActiveChannels in composite image

[grimper]

Hello,

In the IJ built-in Macro, there is  "Stack.setActiveChannels(string)" to set the displayed channels in composite image. Does it exist any expression like "Stack.getActiveChannels(string)" to get the displayed channels?

Actually, what I want to do is to write a little macro to activate and deactivate specific channels by using keyboard shortcut.

Thanks,

Zong

The v1.43d daily build adds a Stack.getActiveChannels(string) macro
function.
