imstack -- stack images into an image of higher dimension


USAGE

imstack images output


PARAMETERS

images

List of images to be stacked.

output

Name of output image created.

title = *

Title of output image. If "*" then the title defaults to that of the first input image.

pixtype = *

Pixel datatype of output image. If "*" then the pixel datatype defaults to that of the first input image.


DESCRIPTION

The input images are stacked to form an output image having one higer dimension than the input images, and a length of that dimension equal to the number of input images. The input images must all be of the same dimension and size.

The output image inherits the world coordinate system (WCS) of the first input image. If the dimension of the input image WCS is greater than or equal to the dimension of the output image, the input WCS is copied to the output image WCS without modification. Otherwise the input image WCS dimension is incremented by 1 and copied to the output image WCS, the input WCS coordinate transformations for each input image axis are copied to the output image WCS without modification, and the new output image axis is assigned a WCS type of 'linear' and the identity transformation.


EXAMPLES

1. Stack a set of four two dimensional images:

cl> imstack image* image.3d

2. To stack a section of images:

cl> imstack image*[1:10,1:10] newimage
