imjoin: Join images along a given dimension

Package: imutil

Usage

imjoin input output join_dimension

Parameters

input: The list of input images to be joined. The input images must have the same dimensionality and the same size along all dimensions but the join dimension.

output: The output combined image.

join_dimension: The image dimension along which the input images will be joined.

pixtype = "": The output image pixel type. The options are in order of increasing precedence "s" (short), "u" (unsigned short), "i" (integer), "l" (long integer), "r" (real), "d" (double), and "x" (complex). If the output image pixel type is not specified, it defaults to highest precedence input image datatype.

verbose = yes: Print messages about actions taken by the task ?

Description

IMJOIN creates a single output image output by joining a list of input images input along a specified dimension join_dimension. IMJOIN can be used to create a single long 1-dimensional image from a list of shorter 1-dimensional images, or to piece together a set of 3-dimensional images into larger 3-dimensional images along either the x, y, or z directions. The input images must all have the same number of dimensions and the same size along all dimensions by the join dimension. The output image inherits the world coordinates system if any of the first input image.

Examples

1.  Join a list of 1-dimensional spectra into a single long output spectrum.

    cl> imjoin @inlist output 1

2.  Join three datacubes along the z direction.

    cl> imjoin c1,c2,c3 c123 3

Timings

Bugs

On some systems there are limitations on the number of input images that can be joined in a single execution of IMJOIN.
