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.
X2 = addborder(X, 20, 62, 'center');
That's what i was searching for, Many thanks!
Fantastic implementation, nice and simple. Well documented. Thank you.
This is a great function. It made my day. However, it gives me an error when I want to use it with grayscale images. Is this only for color images? Do you know a workaround grayscale images? That would be great. Thanks for a good job.
The function works perfectly, however, it could have a better help to explain where X comes from: X in the example is the input image (or IMG) for which you want to show (e.g., using imshow). In fact, this function turns the marginal pixels to the values given by color. My suggestion is to assign default values for T, C and Stroke, something like: T=1 pixel, C=0=black, S= 'center'. Its a great function anyway, thanks for sharing.
Awesome. Just what I needed.
Where doese the X from your example come from? It is not working at all. The 't' is limited to 1 and what I get is only img2 = 'c' depends on what is entered to 'c'.
