image (Simulink Reference)

Simulink Reference

image

Display an image on the icon of a masked subsystem

Syntax

```
image(a)
```

image(a, [x, y, w, h])

image(a, [x, y, w, h], rotation)

Description

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 (such as GIF) to the necessary matrix format.

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'.

Examples

This command

```
image(imread('icon.tif'))
```

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

The following commands read and convert a GIF file, label.gif, to the appropriate matrix format. You can type these commands in the Initialization pane of the Mask Editor.

[data, map]=imread('label.gif');
pic=ind2rgb(data,map);

Then type the command

```
image(pic)
```

in the Icon pane of the Mask Editor to read the converted label image.
