void userToDeviceDistance(out double dx, out double dy)Transform a distance vector from user space to device space. This function is similar to cairo.context.Context.userToDevice except that the translation components of the 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) |
