Comment 2 for bug 678906

More investigation.

Fulla will output the same type of image that is passed as in as input. As such, some input image formats do not have alpha channels, jpeg for example, a conversion on output to another format that supports alpha channels would be required. This is what nona does, for example. Pass nona a jpg and it will put out a tif with an alpha channel.

Do we want to change fulla to always output tifs no matter what the input is?
