Select the masked block that requires the icon.

On the Block tab, in the Mask group, click Edit Mask.

In the Icons & Ports tab, enter this command in the Icon Drawing commands pane:

% Use specified image as mask icon
image('engine.jpg')

The image file must be on the MATLAB^® path.

For more examples of drawing command syntax, see Icon drawing commands.

Images in formats .cur, .hdf4, .ico, .pcx, .ras, .xwd, .svg cannot be used as block mask images. However, you can use images in these formats if you wrap the file name in the imread() function and use the RGB triplet. Using the imread() function is not efficient. However, it is still supported for backward compatibility.

Select the masked block that requires the icon.

On the Block tab, in the Mask group, click Edit Mask.
