Summary0008333: MetaImageIO does not read correctly stream with non-uniform image spacing
DescriptionIf MetaImageIO is configured for streaming, it will produce blank regions as output if the image spacing is non-uniform. The MetaIO library will produce an error similar to:

MetaImage: M_ReadElementsROI: data not read completely
   ideal = 131072 : actual = 0

Steps To Reproduce
Additional InformationThis can be reproduced by changing itkMetaImageStreamingWriterIOTest2 to:

ADD_TEST(itkMetaImageStreamingWriterIOTest2 ${IO_TESTS}
  --compare ${ITK_DATA_ROOT}/Baseline/IO/mri3D.mhd
            ${ITK_TEST_OUTPUT_DIR}/mri3DWriteStreamed.mha
  itkMetaImageStreamingWriterIOTest
            ${ITK_DATA_ROOT}/Input/mri3D.mhd
            ${ITK_TEST_OUTPUT_DIR}/mri3DWriteStreamed.mha)

itkMetaImageStreamingWriterIOTest2 references /nfs/mead/Users/blowek1/src/Insight/Testing/Data/Input/mri3D.mhd which references dicom files. This is the most likely cause of this test not producing the correct output

I incorrectly diagnosed this problem. The errors were also caused by incorrectly streaming/pasting when an file already exists. In addition to the above cause too.
