DESCRIPTION
These function perform a band-wise join of two or more images. Input
images should be of the same type and should have the same sizes.
im_bandjoin()
performs a band-wise join of two images. If the two images
have n and m bands respectively, then the output image will have n+m
bands, with the first n coming from the first image and the last m
from the second.
im_gbandjoin()
performs a generalised band-wise join of no images.
Input images can have any number of bands; for instance if imarray[0] has j
bands, imarray[1] has k bands, ...., imarray[no-1] has z bands, output
has j+k+...+z bands.
RETURN VALUE
The functions returns 0 on success and -1 on error.
