[Tiff] TIFF Tag MD ScalePixel

2022-04-01 Thread Tommaso Vinci
Hello,
I'm trying to read a tiff variant (a .gel file) which has the ScalePixel
field. According to here:

https://www.awaresystems.be/imaging/tiff/tifftags/mdscalepixel.html

ScalePixel is a "Rational"

Any idea which type this corresponds in c or c++  ?

Thanks a million!

T.
