[Insight-users] Re: How to make COM wrapper for ITK

[Luis Ibanez]

Hi Gopal

You can modify ImageEntropy1 to write its output in text file.

Just add the following code in line 270 of ImageEntropy1.cxx


   std::ofstream outputFile;
   outputFile.open("entropyValue.txt");
   outputFile << Entropy << std::endl;
   outputFile.close();


Then from your .NET program you could open the "entropyValue.txt"
file and read the Entropy value.

The code in your .NET program should look very similar:

   double Entropy;
   std::ifstream inputFile;
   inputFile.open("entropyValue.txt");
   inputFile >> Entropy;
   inputFile.close();



Regards,


   Luis
