Detailed Description

Copies images or channels to another image. Does not scale intensities. Target type will be set, if unset.

To copy green channel to red:

drainage image.png --iCopy f --view g --iCopy r --view f  -o copy.png

To extract the third channel (#2, blue):

drainage image.png --view 2  -o blue.png
drainage image.png --view b  -o blue2.png

To convert an image to a 16-bit image:

drainage image.png --target S --iCopy f  -o copy16bit.png

To create alpha channel from channel #1 (green):

drainage image.png --iCopy f --view b --iCopy a  --view f -o copy-rgba.png

In drainage, see also –inputAlpha .
