Comment(by dzwarg):
Replying to [comment:8 pracine]:
> If I remember well we have to move the pixeltype parameter to get the
same parameter order of other MapAlgebra variants allowing to pass extra
parameters to the user custom function. Right?
Yes, that's correct. The order of the parameter has to change to bring
pixeltype in front of the algebra expression, in addition to making
pixeltype required. It may still be NULL, but it is no longer an optional
parameter. These changes are in r7625, so an update should get you the new
versions. I've updated the documentation and all the tests, please let me
know if I've missed anything.
