1 | function [H,J] = imarray(A,varargin) |
---|
2 | % IMARRAY Display array of images |
---|
3 | % IMARRAY(A) plots the array of images A. A can be either a M*N*K |
---|
4 | % array, storing one intensity image per layer, or a M*N*3*K array, |
---|
5 | % storing one RGB image per layer. |
---|
6 | % |
---|
7 | % H=IMARRAY(...) returns the handle H of the axis where the image is |
---|
8 | % plotted. |
---|
9 | % |
---|
10 | % [H,J]=IMARRAY(...) returns the plotted image J as well. |
---|
11 | % |
---|
12 | % The function accepts the following option-value pairs: |
---|
13 | % |
---|
14 | % 'Spacing' [0] |
---|
15 | % Orlates the images with a black border of the specified width. |
---|
16 | % |
---|
17 | % IMARRAYSC(A, 'Spacing', spacing) is another way of specifying the |
---|
18 | % spacing. |
---|
19 | % |
