In addition to scaling, it is possible to add black padding around images and crop them to specified size. Useful to when generating initial image for iPhone or iPad:

<goals>
    <goal>scale</goal>
    <goal>crop</goal>
</goals>
<configuration>
    <images>
        <image>
            <source>src/main/icons/launcher.png</source>
            <destination>Default@2x.png</destination>
            <width>240</width>
            <cropWidth>640</cropWidth>
            <cropHeight>960</cropHeight>
            <color>black</color>
        </image>
    </images>
</configuration>

The color can be specified by name of one fields of java.awt.Color, or by integer value: 0xffff00 is the same as yellow.
