Fix: Internal storage of rational tags changed from float to native rational values.
Solves issue #226 (Impossibility to set the resolution with a rational)
The internal storage of RATIONAL tag values has been changed from float values to real rational value pairs.
- Increasing the accuracy (precision).
- Additional interface to directly write / read rational value pairs. This gives the user the possibility to increase / determine the accuracy of rational values.
-
TIFFSetFieldRational()
, -
TIFFGetFieldRational()
This routines expect as va_list: Numerator , Denominator as uint_32 (or int_32 for signed rationals).
-
- The existing interface (with float) is retained.
- Conversion programmes are now available externally:
-
DoubleToRational()
, DoubleToSrational()
-
