Parameters
- x
- Type: SystemSingle
X-coordinate of the point - y
- Type: SystemSingle
Y-coordinate of the point - size
- Type: SystemSingle
Feature size - angle (Optional)
- Type: SystemSingle
Feature orientation in degrees (has negative value if the orientation is not defined/not computed) - response (Optional)
