Thanks for this - BTW, what is the utility of having the "val" parameter here?

I found this in saga, not in OTB: am I wrong?

BTW, I get an error while using shape to grid (saga):

An error has occured while executing Python code:

Traceback (most recent call last):
  File "/home/paolo/.qgis//python/plugins/sextante/gui/ParametersDialog.py", line
147, in accept
    if self.setParamValues():
  File "/home/paolo/.qgis//python/plugins/sextante/gui/ParametersDialog.py", line 98,
in setParamValues
    if not self.setParamValue(param, self.paramTable.valueItems[param.name]):
  File "/home/paolo/.qgis//python/plugins/sextante/gui/ParametersDialog.py", line
139, in setParamValue
    return param.setValue(widget.getValue())
  File "/home/paolo/.qgis//python/plugins/sextante/parameters/ParameterExtent.py",
line 11, in setValue
    if value is None:
NameError: global name 'value' is not defined

All the best.
