[vtkusers] about the BMP slices Read & 3D Rendering

[Marcelo Costa Oliveira]

Hi Yan, How are u ??
I read a stack of 512 X 512 with 120 slices. The code that i read DICOM
isn´t my mine and i have to get permission to send the code for you, sorry.
TRy to find the DICOM2 is a open source code to read DICOM.

vtkImageReader *v16 = vtkImageReader::New();
   v16 -> SetHeaderSize ( 0 ); // 350
   v16 -> SetDataExtent( 0, 511, 0, 511, 1, 120 );
   v16 -> SetDataSpacing ( 1, 1, 3.5 );
   v16 -> SetDataScalarTypeToUnsignedShort ();
   v16 -> SetDataByteOrderToLittleEndian();
   v16 -> SetFileDimensionality( 3 );
   v16 -> SetFilePattern( "tumor.vtk" );
   v16 -> SetFilePrefix( "tumor.vtk" );
   v16 -> SetDataMask(0x7fff);
