Displaying Images on Masks

The masked dialog functions, image and patch, enable you to display bitmapped images and draw patches on masked block icons.

image(a) displays the image a where a is an M by N by 3 array of RGB values. You can use the MATLAB commands, imread and ind2rgb, to read and convert bitmap files to the necessary matrix format. For example,

reads the icon image from a TIFF file named icon.tif in the MATLAB path.

image(a, [x, y, w, h]) creates the image at the specified position relative to the lower left corner of the mask.

image(a, [x, y, w, h], rotation) allows you to specify whether the image rotates ('on') or remains stationary ('off') as the icon rotates. The default is 'off'.

patch(x, y) creates a solid patch having the shape specified by the coordinate vectors x and y. The patch's color is the current foreground color.

patch(x, y, [r g b]) creates a solid patch of the color specified by the vector [r g b], where r is the red component, g the green, and b the blue. For example,

creates a red triangle on the mask's icon.
