1998.12.30 20:12 "writing Xresolution and Yresolution", by Sim Zacks
The Tiff 6.0 spec says that XResolution and Yresolution are Rationals which is 2 longs (one is divided by the other). I looked in Tiffcp, and TiffSplit and they are using floats for a Rational.
But when I try that, it doesn't seem to work. And when I look up what the tag is in other programs, it says 0. Is this a bug, or am I doing something wrong? How can I correctly set these fields?
