[ITK] [ITK-users] Imagebase:: A spacing of 0 is not allowed.

[UJJWAL aryan]

Hi,

I figured out that the problem is happening in the final of the code where
the ImageFileWriter is invoked. As I do writer->Update(), it throws an
exception. The error is as follows :

itk::ExceptionObject (0x14f1a60)
Location: "void
itk::ImageBase<VImageDimension>::ComputeIndexToPhysicalPointMatrices()
[with unsigned int VImageDimension = 2u]"
File: /usr/local/include/ITK-4.5/itkImageBase.hxx
Line: 184
Description: itk::ERROR: Image(0x14f2ab0): A spacing of 0 is not allowed:
Spacing is [0, 0]

I do not understand that why this error is coming. Would I need to set the
physical spacing and everything manually ?
