TIFF: What does a Resolution Unit of 2 or 3 mean?

Question by Guest | 06/01/2018 at 23:18

When I click on a TIFF or TIF file in Windows Explorer, I get some information about the image in the Details tab of the Properties Dialog.

Among other things, I can find the entry resolution unit there, where I could see only the values 2 or 3 so far. Can someone explain to me what that resolution unit information should be?

The resolution unit is the unit of measure used for the X or Y resolution of the image.

  • A value of 2 means that the unit is inches, so the resolution is to be interpreted as dots per inch (dpi).
  • A value of 3 means that the resolution should be interpreted in centimeters, that is dots per centimeter (dpcm or dpc).
  • If there is a 1 at this place, it means that no unit was specified for resolution.

The numbers are coming from the internal Tiff Tag 296, in which the unit used for the resolution is coded with these numbers.
