Can I save a Group as PNG? #180

Is there any way I can get a group's image? Thanks

The PSD file doesn't contain pre-rendered group bitmaps, you'd have to manually composite bitmaps of all layers inside the group yourself. Depending on if you're using effects or special filters it can be really easy to do or very hard. If you're not using any layer effects or special filter layers it would be as simple as calling drawImage for each layer.
