Overview
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.
