ValueError: image has wrong mode

[mbaechtold]

When I try to generate a DZI from the file available at https://www.sendspace.com/file/yskm3h, I get the exception ValueError: image has wrong mode:

from deepzoom import ImageCreator
creator = ImageCreator()
source = "/path/to/image"
destination = "/path/to/dzi"
creator.create(source=source, destination=destination)

Here's the traceback:

ValueError: image has wrong mode

Do you have an idea why this happening?

The calling code should handle such errors. So I'm closing this issue.
