Displaying an FXG file in a Spark BitmapImage control in Flex 4

The following example shows how you can display an FXG file in a Spark BitmapImage control in Flex 4 by setting the source property using data binding or MXML.

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

For more information on getting started with Flex 4 and Flash Builder 4, see the official Adobe Flex Team blog.

<s:Application name="Spark_BitmapImage_source_FXG_test"
        xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/mx">
    <s:layout>
        <s:VerticalLayout horizontalAlign="center" verticalAlign="middle" />
    </s:layout>
 
    <fx:Script>
        <![CDATA[
            import assets.*;
        ]]>
    </fx:Script>
 
    <s:BitmapImage id="bmpImg" source="{Chevron}" />
 
</s:Application>

And the FXG file, assets/Chevron.fxg, is as follows:

<?xml version="1.0" encoding="UTF-8"?>

<Graphic xmlns="http://ns.adobe.com/fxg/2008"
        xmlns:d="http://ns.adobe.com/fxg/2008/dt"
        xmlns:fc="http://ns.adobe.com/flashcatalyst/2009"
        version="2.0">
    <Path y="1" data="M 2 0 L 7 7 L 2 14 L 0 14 L 5 7 L 0 0 L 2 0 Z">
        <fill>
            <SolidColor color="#000000" alpha="0.6"/>
        </fill>
    </Path>
    <Path data="M 2 0 L 7 7 L 2 14 L 0 14 L 5 7 L 0 0 L 2 0 Z">
        <fill>
            <SolidColor color="#FF0000"/>
        </fill>
    </Path>
</Graphic>

View source is enabled in the following example.

Or you can set the BitmapImage control’s source property using MXML, as seen in the following example:

<?xml version="1.0" encoding="utf-8"?>

        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/mx"
        xmlns:assets="assets.*">
    <s:layout>
        <s:VerticalLayout horizontalAlign="center" verticalAlign="middle" />
    </s:layout>
 
    <s:BitmapImage id="bmpImg">
        <s:source>
            <assets:Chevron />
        </s:source>
    </s:BitmapImage>
 
</s:Application>

This entry is based on a beta version of the Flex 4 SDK and therefore is very likely to change as development of the Flex SDK continues. The API can (and will) change causing examples to possibly not compile in newer versions of the Flex 4 SDK.
