Asuming you are refering to LibTiffDelphi, it is a known problem. It
works only if you pass a variable declared as double to TIFFSetField to
set tags like TIFFTAG_XRESOLUTION and TIFFTAG_YRESOLUTION. So change the
above two lines of your code to look like this:

var
  m: Double;
begin
  ...
  m=200;
  TIFFSetField(OpenTiff, TIFFTAG_XRESOLUTION, m);
  TIFFSetField(OpenTiff, TIFFTAG_YRESOLUTION, m);
