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
dx | X component of a distance vector (in/out parameter) |
dy | Y component of a distance vector (in/out parameter) |
