Use the TIFF tags TIFFTAG_RESOLUTIONUNIT, TIFFTAG_XRESOLUTION, and TIFFTAG_YRESOLUTION with the TIFFSetField() function. TIFFTAG_RESOLUTIONUNIT supports the values RESUNIT_NONE, RESUNIT_INCH, or RESUNIT_CENTIMETER. If you mean to do this from the command line, then see the documentation for the 'tiffset' utilitity. This documentation even comes with an example for how to set the resolution.
