Context.deviceToUserDistance

void deviceToUserDistance(out double dx, out double dy)

Transform a distance vector from device space to user space. This function is similar to [cairo.context.Context.deviceToUser] except that the translation components of the inverse CTM will be ignored when transforming (dx,dy).

Parameters

dxX component of a distance vector (in/out parameter)
dyY component of a distance vector (in/out parameter)
