Step 3: Setting the correction angle
1. | Select the Rotate option, and enter -16.17 in the Angle (Deg) field. (To measure this rotation angle, refer to Measuring the rotation angle of an object.) |
2. | From the Interpolation bits drop-down list, select 8 bits to get a better result. |
3. | Click Execute to perform the operation. |
