Trying to read a 16-bit grayscale TIFF image saved with OpenCV in Python, and I’m getting the error:

> ERROR: In C:\glr\builds\paraview\paraview-ci\build\superbuild\paraview\src\VTK\IO\Image\vtkTIFFReader.cxx, line 1136  
> vtkTIFFReader (0000027E675D81C0): Problem reading slice of volume in TIFF file.

The same error message appears in [this thread](https://public.kitware.com/pipermail/paraview/2014-November/032710.html) from the old mailing list. Image properties from metadata:

```auto
Exif.Image.BitsPerSample = 16 16 16
Exif.Image.Compression = LZW
Exif.Image.ImageLength = 120
Exif.Image.ImageWidth = 160
Exif.Image.Orientation = top, left
Exif.Image.PhotometricInterpretation = Black Is Zero
Exif.Image.PlanarConfiguration = 1
Exif.Image.Predictor = Horizontal differencing
Exif.Image.ResolutionUnit = inch
Exif.Image.RowsPerStrip = 25
Exif.Image.SamplesPerPixel = 1
Exif.Image.StripByteCounts = 4189 4188 4338 4119 3429
Exif.Image.StripOffsets = 8 4197 8385 12723 16842
Exif.Image.XResolutoin = 300
Exif.Image.YResolution = 300
Exif.Photo.ColorSpace = sRGB

```

Because the extension is .tif, I get the option of two readers, either GDAL Raster Reader (works for a single image but not a sequence) or TIFF Series Reader (gives error above, whether the image is alone or is actually part of a series titled `seq_0000xx.tif` for xx=0 to 40. `Read As Image Stack` is unchecked, representation can be surface or slice, coloring is set to Tiff scalars. Everything else is default.

These are plain 16-bit grayscale TIFF files, no pages or anything in them. `Information` tab shows data is read as unsigned short.

Here are sample images:  
[seq\_0000000.tif](https://discourse.paraview.org/uploads/short-url/ov1zABxTROEemcUnaHuDMl5SvYv.tif) (20.0 KB)  
[seq\_0000001.tif](https://discourse.paraview.org/uploads/short-url/oSnaQSZMoA9qkeNrOFPmDDUj7fj.tif) (20.0 KB)  
[seq\_0000002.tif](https://discourse.paraview.org/uploads/short-url/utmYs25YI1bSR5fI6D5iHaVXLiR.tif) (20.1 KB)  
[seq\_0000003.tif](https://discourse.paraview.org/uploads/short-url/RhAw3RgGve5NHx3MbatjOOECVX.tif) (20.0 KB)

The data originates from a thermal camera which gives raw 12-bit data, so changing the format isn’t too much of an issue but this should work.
