: rgb = ind2rgb (x, map)

: [R, G, B] = ind2rgb (x, map)

Convert an indexed image to red, green, and blue color components.

The image x must be an indexed image which will be converted using the colormap map. If map does not contain enough colors for the image, pixels in x outside the range are mapped to the last color in the map.

The output may be a single RGB image (MxNx3 matrix where M and N are the original image x dimensions, one for each of the red, green and blue channels). Alternatively, the individual red, green, and blue color matrices of size MxN may be returned.

Multi-dimensional indexed images (of size MxNx1xK) are also supported.
