ftcommon.c:
*************************************************************************
void
FTDemo_Set_Preload( FTDemo_Handle* handle,
int preload )
{
handle->preload = !!preload;
}
Q1: why two '!' here ?
void
FTDemo_Set_Current_Pointsize( FTDemo_Handle* handle,
int point_size,
int res )
{
FTDemo_Set_Current_Size( handle, ( point_size * res + 36 ) / 72 );
}
Q2: what's the mean of: "( pt * res + 36 ) /72" ?
