I have a TIFF image with four channels downloadable here.
With the following IJMacro command:
Stack.setDisplayMode("composite"); Stack.setActiveChannels("1001"); run("Scale Bar...", "width=500 height=12 font=70 color=White background=Black location=[Lower Right] bold serif overlay label");
I get this image:
There Channel 1 is red and Channel 4 are marked by white specks.
What I want to do is to change the color from red to white in Channel 1 and
from white to green in Channel 4. How can I do it?
