The data I work with (medical images) are frequently grayscale, 16 bit images (or a single 16 bit channel). I guess that in other scientific applications, 16 bit images are also used. I'm not sure what the downside of using the 16 bit version is. Just a snippet from the README in the download folder of GraphicsMagick: -x-x- If the file has "Q8" in the name, then it is compiled to support 24/32 bit pixels. If the file has "Q16" in the name, then it is compiled to support 48/64 bit pixels. Most users will find that the "Q8" builds to be sufficient for their needs. They execute faster than the "Q16" builds and take less memory. Users who are using CMS color profiles, or are processing scientific/medical images will likely want to use a "Q16" build. Binaries are built using Microsoft Visual Studio .net Professional, 2002 edition, (VC++ 7.0). -x-x- I guess they agree with my need for 16 bits :-) Thanks for the support!
