Is it possible to use a gif with a transparent bg as a mask. I have a puzzle that I am creating and I want to use a shaped gif image to create oddly shaped pieces. As it stands just now the whole gif image (including transparent areas) is being used as the mask.

```php

_root.mc_template.createEmptyMovieClip("mc_mask", 4);
loadMovie("images/0/mask_0.gif", _root.mc_template.mc_mask);
_root.mc_options.mc_envelope.mc_image.setMask(_root.mc_template.mc_mask);

```
