The BitsPerSample required values for Grayscale and Palette-color Images are 4 and 8 according to the TIFF 6.0 Specification. Does it mean that TIFF does not support BitsPerSample values > 8 bits for these images?

If not, do you know any viewing tool which is able to display 12 bits-TIFF images?

I use 16-bit TIFF images and have submitted changes to the shareware xv viewer to display both 16-bit RGB and grayscale images. I

Notice in the original message, he's talking about Grayscale and Palette-color images, not RGB. The TIFF 6.0 standard does support 16 bit RGB images, and so does libtiff. However the standard doesn't support 12 or 16 bit Palette or Grayscale images, and I don't know whether libtiff does.
