# Bug: vtkMetaImageWriter not writing vtkMetaImage Direction Matrix to the TransformMatrix line

Also, a related bug: the `vtkMetaImageReader` does not read the `TransformMatrix` line.

For example, see the sample .mhd file attached. It has a non identity `TransformMatrix`.
(well… nvm as a new user i cant upload attachements…)

using the `vtkMetaImageReader` to read the image, you’ll get an identity matrix when calling `.GetDirectionMatrix()` instead of the `TransformMatrix` written in the file.

When using `vtkMetaImageWriter`, the writer will not write the `Direction Matrix` to the `TransformMatrix` line.
