| Hello,
| 
| I want to transform a greyscale image (represented as RGB png) in a mask
| where white
| is transparent, black is opaque and the greyscales are more or less
| transparent dependent
| on their brightness. The example image is a shape that should become a
| mask with blurred
| edges
| http://www.vi-anec.de/Trance-Art/IM-examples/IMCompose/SShape-002.png
| The mask should be used in the compose operation to get a continuos/soft
| change.
| How could this be achieved with IM/PerlMagick? Thank you!
| 
| regards
| Günter
