RGB2MONO Purpose: Converts an RGB image to an 8 bit monochrome image. Format: RGB2MONO(inwin) inwin - A series or Window. The source image. Returns: An array, an 8 bit monochrome image. Example: W1: density(spline2(ravel(gnorm(100,1),10),8));rainbow W2: image24(W1) W3: rgb2mono(W2) W1 contains an image of a random surface shaded with the colors of the spectrum ranging from red to blue. W2 converts the image into a 24 bit color image. W3 contains the monochrome image displayed in the current colormap. The monochrome image contains values ranging from 0 to 255. Remarks: RGB2MONO converts the 24 bit image into 8 bit integer values ranging from 0 to 255. The resulting image is displayed using the current colormap. For each RGB pixel, the converted pixel is determined as follows: mono = 0.56*r + 0.33*g + 0.11*b where r, g, b are the red, green and blue components of the original RGB image.
