Hi,
I'll re ask my question, because I have no answer and I need it. My 
question is how to write a tiff file from scratch adding several 
color channels. That means, can I write a fiew NSImage objects I 
obtain from somewhere else into different color channels in a new 
tiff file?

Thanks in advance
Julio
