[Proj] rectObj Class

[Antonio]

Hi All,
I am using rectObj class in C# . When I create a new instance it aspect 
5 parameters.
The last one is int imageunits.
First of all: What kinds of value I have to set for this parameter.
And I tried to set it at 1 (one) but didn't compile.
The documentation page about rectObj say that the constructor needs 4 
parameters.
Is there any one that know what happen and what I could do?

Thanks

Antonio
