The following example shows how you [...]]]> In a previous example, “Setting the fill mode on a Spark Image control in Flex Hero”, we saw how you could set the fill mode on a Spark Image control in Flex Hero by setting the fillMode property to one of the static constants in the mx.graphics.BitmapFillMode class.

The following example shows how you can set the scale mode on a Spark Image control in Flex Hero by setting the fillMode property to “scale” and setting the scaleMode property to one of the static constants in the mx.graphics.BitmapScaleMode class.

The following example(s) require Flash Player 10 and the beta Adobe Flex Hero SDK. To download the Adobe Flash Builder 4 trial, see http://www.adobe.com/products/flex/. To download the latest nightly build of the Flex Hero SDK, see http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+Hero.
