Hi there, I processed images(.tif format) in Mathematica and then exported them as .tif images. But when I impoted the new image into ParaView, the image could not display normally. To find the reason, I tried to export images with different format including .tif 16-bit, .tif 8-bit, .png, .jpeg and then read them in ParaView. The results show that only .tif image created from Mathematica cannot display correctly in ParaView. It seems that partial pixel intensity of image is lost. Does anyone know how the Mathematica exports .tif images? Will it cause the loss of pixel intensity of image? Why can original image with 8-bit and tif format display normally in ParaView but the image exported as 8-bit, tif format from Mathematica not?

Although I imported image as 8-bit depth, when I use ImageType function, it still showed bit 16. I know Mathematica will export image as 16-bit depth by default so I set up bit depth as 8.

The code in Mathematica is :

SetDirectory[NotebookDirectory[]];
Fibreimage = Import["8.tif", "BitDepth" -> 8];
ImageType[Fibreimage]
Export["8tif.tif", Fibreimage]
Export["bit8tif.tif", Fibreimage, "BitDepth" -> 8]
Export["png.png", Fibreimage]
Export["jpeg.jpeg", Fibreimage]

The original image is

The visualisation of image with different format in ParaView is shown in below.
