4.3.5. Linearity (G)
The Linearity adjustment corrects for improper horizontal or vertical grid
spacing on an image. With distorted linearity, lines in the grid are spaced
closer together on one side and farther apart on the other (refer to Figure
4.0-8 Linearity Distortion).
To correct for Linearity Distortion:
1. Select LINEARITY from the GEOMETRY MENU.
2. Toggle the RGB KEY to select G only.
3. Use the HIDE KEY and hide R and B.
4. Use left/right arrows to correct horizontal linearity distortion and
up/down arrows to correct vertical linearity distortion. Make grids the
same width on the left/right side and the same height at the top and
bottom.
5. Use EDGE LINEARITY ADJUSTMENT to perform additional linearity
correction.
6. Press ESCAPE/ENTER to exit.
Vertical Linearity Distortion. Use up/down arrow keys to correct.
