Member Data Documentation

double Converter::ICS_ORIGIN = -0.5 [static]
 

The origin of the ICS is at (-0.5, -0.5).

double Converter::ICS_EPS = 0.001 [static]
 

The correction factor makes sure that a point is mappend onto the correct CCS value, i.e.

the point (0,0) has to be mapped onto (0,0), and not (1,1).
