Hi,
I'm currently about learning about compositing in IM, but I have
the impression that there's an error in the respective section in
'Usage' <http://www.imagemagick.org/Usage/compose/>:
The example code is:
|convert bgnd_overlaid.png bgnd.png \
-compose ChangeMask -composite bgnd_removed.png
|
(The example is about two third down the page.)
In the description of 'compose'
<http://www.imagemagick.org/script/command-line-options.php#compose>,
there's only the operator `change-mask'
available (not `ChangeMask').
When I correct this (I have written a small shell script for this), I am
getting
the error message
convert: unrecognized compose operator `change-mask'.
What would be the proper syntax here?
TIA,
Claus
P.S.: Those minor problems aside, I'm really amazed at what IM
can do! ;-)
