<s:Application .. transitions="{[bm_tran]}" > <s:states> <s:State name="state1" /> <s:State name="state2" /> </s:states> <fx:Declarations> <s:Transition id="bm_tran"> <s:Sequence target="{bitmapimage1}" duration="500"> <s:Resize /> <s:Pause/> <!-- seem isn't available --> <s:CrossFade /> </s:Sequence> </s:Transition> </fx:Declarations> <s:BitmapImage height.state2="113" height.state1="149" id="bitmapimage1" source.state2="@Embed('Image_0002.png')" source.state1="@Embed('Image_0001.png')" width="429" /> <s:Button label="Click Me!" click="{currentState = (currentState == 'state1') ?
