tiff specification for 16-bit grayscale

for an xray-application I need a 16-bit grayscale tiff image. However, reading through the tiff specification (Revision 6.0, Final — June 3, 1992), I just found, that 4 and 8 bit are specified for grayscale images (c.f. Section 4).

Is there a newer specification and where can I get it? Or can someone please explain me the 16-bit grayscale specification, such that I can code it (in C/C++ and Java)? Is it just setting BitsPerSample = 16 or must I do something else?

Thanks

Note that LibTIFF is:

  1. NOT at libtiff.org. It's at https://gitlab.com/libtiff/libtiff . Someone stole their website back over 20 years ago (imagine that), and libtiff.org contains but an old version!

  2. Has buffer overflow issues, so be careful when reading TIFF files of unknown provenance with it!

  3. Has been reported to be slow when writing multi-frame images. Apparently time to write a frame grows proportionally with the frame number. Google TinyTIFF for one existing solution, or spin your own.

libtiff supports 16 bpp images. Such images, produced by libtiff, are recognized by another programs, such as ImageJ - you can use it for testing. libtiff library is available here http://www.libtiff.org/ and can be used in C/C++ programs.
