Spatial Modeler Discussions

Hi

I know how create spatial models from scratch using python, and when doning this it's easy to add a Conditional-operator.

conditional = modeler.Operator(m, 'Conditional', Test1=<someRaster>, Value1=<someOtherRaster>)

But I havn't figured out how to add a second condition using python.

In the Spatial Model Editor it's possible to click the "Add port" option on several operators. What I really want to know is how to do this using python.

The Expand function will do the same thing as adding a port in Spatial Model Editor.  Here's an example of its use.

from imagine import modeler

m = modeler.Model()
rasterInput = m.RasterInput(Filename="d:/work/lanier.img")
rasterInput2 = m.RasterInput(Filename="d:/work/lanier.img")
conditional = modeler.Operator(m, "Conditional", Test1=rasterInput, Value1=rasterInput2)

# Equivalent to adding a port in the UI
conditional.Expand()

# If connecting new port to a port upstream
conditional.ConnectParent(rasterInput.GetPort("RasterOut"), conditional.GetPort("Test2"))

# If setting a value on the new port
conditional.GetPort("Value2").data = "1"

rasterOut = m.RasterOutput(conditional, "d:/work/newOutput.img")

modeler.Solution.Save(m, "d:/work/model.gmdx")

m.Execute()

Tnx! This was exactly what I was looking for.
