transparency

I am fairly inexperienced with Flex, but my googling has retrieved nothing to suggest this is an obvious question.

I have an mx:Button with an Icon on it that is a png file with a transparent background, as below, however the transparency is not working, and the icon is painted with a white background.

<mx:Button label="Button" icon="@Embed(source='images/clearTracks.png')"/>

I have seen how to use a ByteArrayImage to get a transparency working on an image, but this technique doesn't appear available for a button's icon property.

In this post we'll look at the AlphaBlend() api and how it can be used for semi-transparent blitting. AlphaBlend() takes a source device context and a destination device context (DC) and combines the bits in such a way that it gives a transparent effect.
