Unfortunately, that generates an error message "Keyword 'transmit' cannot be
used with non color-mapped image."

I'm currently using a workaround, which is to apply the transparency with a
paint program. Since this is for an animation though, it means preparing many
images with varying transparency instead of one image that "transmit" can be
applied to.
