Expose FilterImage through the Magick++ Image interface

[hwenjing]

My code on testing this on 6.9.0-6
Almost all were copied from what ImageMagick suggested.
I have no idea what causes the difference between our test code and theirs.

Code: Select all

#include "third_party/ImageMagick6/Magick++.h"

using namespace std; 
using namespace Magick; 

int main(int argc,char **argv) 
{ 
  InitializeMagick(*argv);

  Image image;
  image.read( "input.png" );
  image.morphology(CorrelateMorphology,
    "-1.0, -2.0, -1.0, 0.0, 0.0, 0.0, 1.0, 2.0, 1.0",1);
  // image.filter("-1.0, -2.0, -1.0, 0.0, 0.0, 0.0, 1.0, 2.0, 1.0");
  image.write( "output.png" ); 
  return 0; 
}
