Save itk image with custom voxel spacing

Hello everyone!
I got output from the model which is a NumPy array of shape [128,448,448 ] .I converted to itkobject using itk.image_view_from_array(predicted_label) and save the image with itkwrite .But shape of input image was [448 448 128] with voxel spacing[0.5134 0.5134 0.8] but itk.write gives output[448 448 128] with voxel spacing [1 1 1 ].Any solution for this problem as I want output image with custom voxel spacing as shape([448 448 128],[0.5134 0.5134 0.8])
I tried to use nibabel but reshape the image distorts the result.

You could use ChangeInformationImageFilter. That is especially easy if you have the original image in ITK format. Example.

Or SetSpacing in your itk python image.

    filter = itk.ChangeInformationImageFilter.New(___) # itk image
    output_spacing = [0.5134, 0.5134 0.8]
    writerInput =filter.GetOutput()
    writer = itk.ImageFileWriter[ImageType].New()

is this will work ?

This should be false, as you are not using a reference image. The rest looks good.

But if you are only looking to change spacing, Pablo’s suggestion is probably simpler.

output_spacing = [0.5134, 0.5134 0.8]
itk.imwrite(image, outputFilePath)

Thank you, sir @dzenanz @phcerdan, it worked.
