Apply a darken-gradient to Bitmap image with AS3

[coldscooter]

I'd like to add a gradient to a .png image (so that one side of the image is darker then the other).

Does anyone know how I might go about this?

Thanks in advance.

Just draw a same-sized rectangle over it with an alpha gradient fill.

But in the case of .pngs I don't want the shadow to show over the transparent areas.

Should have mentioned that in the first post. Time for you to learn Pixel Bender then and create a shader.

I'll take a look into that. Thanks for the reply.
