> Any ideas on why the alpha isn't getting copied quite right? > Hi Kerry, Getting the right degree of transparency is a tricky business. I took a brief look at James code and it creates a new alpha channel. I would try making a new alphaMaskImage by duplicating the mask image and then copying black/white onto it using the original alpha image as a mask in the copypixel parameters. That way you can over/under expose the mask area to achieve a better result. You may want to add a blend level too. I once experimented with this approach but it uses a complicated manner of overexposing the alpha only in the transparent areas. http://www.dia3.de/director/source/composer.htm Is it possible that the shadow area being masked (ie. having transparency) is not solid black? Another idea that might work: I noticed once when using Warner Sharp's Export bitmap for a screen shot tool of the stage, the image of the stage had an alpha from the last sprite draw it did in the exported bmp. I had to kill the alpha to get normal screen shots. If need be, I can look at that code again and find out if that alpha information could be used.
