)- Description
Transform a distance vector from device space to user space. This function is similar to device_to_user() except that the translation components of the inverse CTM will be ignored when transforming (dx, dy).
- Parameter
dx
X component of a distance vector (in/out parameter)
- Parameter
dy
Y component of a distance vector (in/out parameter)
- Returns
The transformed distance vector
Array float
0
X component of the new distance vector
