A Colour filter error: ITK Montage Module

, ,

I encountered a similar problem like before mentioned in this thread (Stacking Z dimension images using SimpleITK - #22 by sleepingcat4) I tried to wrap and the error were persistent. Any help would be amazing : )

CODE:

print("Producing the mosaic")
resampleF = itk.TileMergeImageFilter[type(color_images[0]), itk.D].New() #  line creating the problem
resampleF.SetMontageSize(stage_tiles.GetAxisSizes())
for t in range(stage_tiles.LinearSize()):
    resampleF.SetInputTile(t, color_images[t])
    index = stage_tiles.LinearIndexToNDIndex(t)
    resampleF.SetTileTransform(index, montage.GetOutputTransform(index))
resampleF.Update()
itk.imwrite(resampleF.GetOutput(), str(output_file))
print("Resampling complete")

Error produced:

What happens if you turn this into:
resampleF = itk.TileMergeImageFilter[type(color_images[0])].New()

I receive almost the same error

That filter should be wrapped for 2D images too:

Can you try this:
