Member Function Documentation

double Unit::convert ( double  value, Unit::MetricalUnit  from, Unit::MetricalUnit  to, int  dpi = 1  )

static

The most useful method of this class: convert the specified value from the unit from to the unit to, using the specified dpi in case of conversions from/to pixels.

Definition at line 86 of file unit.cc.

void Unit::convertTo

(

Unit::MetricalUnit

unit

)

Set the unit of the current object to unit and convert the value to the new unit using convert().
