Hello All
I am implemented the following piece of code....
X = 512;Y = 512;Z = 243 ;
s1 = 1.96;s2 = 1.96;s3 = 2.5;scale = 1;
vtkPNMReader *Reader = vtkPNMReader::New ();
Reader->SetFilePrefix ("c340007.ppm");
Reader->SetDataExtent (0,X,0,Y,0,Z);
Reader->SetDataSpacing (s1*scale, s2*scale, s3*scale);
Reader->SetDataScalarTypeToUnsignedChar ();
Reader->Update ();
vtkImageClip *imclip = vtkImageClip::New ();
imclip->SetInput (Reader->GetOutput ());
imclip->SetOutputWholeExtent (0,X,Y/2,Y/2,0,Z);
vtkTIFFWriter *writer = vtkTIFFWriter::New ();
writer->SetFileName ("test.tiff");
writer->SetInput (imclip->GetOutput ());
writer->Write ();
On Implementing this..test.tiff contained a thin line which is the slice
information.
When I tried imclip with a constant Z I got a correct image with dimension
512 x 512 x1..but here I am getting an image with dimension 512 x1; whereas
the dimensions are 512x1x243.
How do I get the image which is represented by 512x243. ?
Thanks
Sincerely
Sathya
