4.9 OBRSetSwingAngle
This function sets up the Scan Width Control. The laser beam irradiation width for each angle can be
set in the OBR calibration. If the setting is not performed, the irradiation width will be automatically
set with the factory default setting.
In the Device Emulator, the function does not perform, but stores the preset value as internal
variable. The value stored can be checked with OBRGetSwingAngle func
tion.
