channels in a tiff file
Posted on 2001-08-23
A tiff file stores multiple channels (red, green, blue) and I can view them in Photoshop quite easily. I'm trying to find a utility I can use on the command line to separate out the channels into individual files. Does anyone have any ideas on how I can do this?
Essentially, what I have is a whole set of tiff files where the R G and B channels are slightly misaligned by a known pixel offset. What I need to do is find a way to break out the different channels and recompose them by correcting the offset and creating a new corrected composite image again. The trick is to automate this process.
This is hard. Any ideas at all will be good.
