ADDBORDER draws a border around an image.

NEWIMG = ADDBORDER(IMG, T, C, S) adds a border to the image IMG with thickness T, in pixels. C specifies the color, and should match the color format of the image (e.g., RGB or indexed). STROKE is a string indicating the position of the border:

'inner' - border is added to the inside of the image. The dimensions of OUT will be the same as IMG.

'outer' - the border sits completely outside of the image, and does not obscure any portion of it.

'center' - the border straddles the edges of the image.

Example:

load mandrill
X2 = addborder(X, 20, 62, 'center');
image(X2);
colormap(map);
axis off
axis image
