[Insight-users] Writing Image Problem

[Selim Hasan]

Hi again,


I added the function that i use to make float number a volume. I tested
 this code with adding only one pixel value, but it didnt work.
I cant also write as dicom image, this functions works without error if i
change the final image to .vtk but I can not see anything in the image.

Can someone help me to solve this problem.

                typedef itk::GDCMImageIO ImageIOType;
 ImageIOType::Pointer gdcmImageIO = ImageIOType::New();
 typedef itk::Image< float, 3 > ImageType;
typedef itk::ImageFileWriter< ImageType > WriterType;
ImageType::Pointer image = ImageType::New();
WriterType::Pointer writer = WriterType::New();
cout<<"MakeImage"<<endl;
 ImageType::IndexType start;
ImageType::SizeType  size;
 size[0]  = 144;  // size along X
size[1]  = 144;  // size along Y
size[2]  = 60;  // size along Z

start[0] =   0;  // first index on X
start[1] =   0;  // first index on Y
start[2] =   0;  // first index on Z
 ImageType::RegionType region;
region.SetSize( size );
region.SetIndex( start );
 image->SetRegions( region );
image->Allocate();
ImageType::PixelType  initialValue = 0;
image->FillBuffer( initialValue );
cout<<"MakeImage"<<endl;
ImageType::PixelType   pixelValue;
ImageType::IndexType pixelIndex;

pixelIndex[0] = 27;   // x position
pixelIndex[1] = 29;   // y position
pixelIndex[2] = 37;   // z position
 pixelValue=0.52356; // TEST
image->SetPixel(  pixelIndex,   pixelValue );
cout<<"MakeImage"<<endl;
writer->SetInput(image);
                writer->SetImageIO(gdcmImageIO);
writer->SetFileName("C:\\selimmingwinput\\test.dcm");
   try
{
writer->Update();
}
  catch( itk::ExceptionObject & e )
{
std::cerr << "WRITER UPDATE ERROR" << std::endl;
std::cerr << e << std::endl;

}
