During initial learning, the anchor region enlarges after performing OCR to keep the region at the same center.
The Height and Width values increase by the smaller value of Height or Width.
The Top and Left values decrease by half of the smaller value of Height or Width.
Note: The Top or Left values
cannot be less than zero. If either is reduced to zero, the region center may shift
right and/or down.
Example
The smaller dimension of Height and Width is 300.
Height and Width increase by 300, while Left and Top decrease by 150.
| Width | Height | Left | Top | |
|---|---|---|---|---|
| Values before Learning | 500 | 300 | 300 | 700 |
| Values after Learning | 800 | 600 | 150 | 550 |
Subsequent learning does not affect the position or size values. However, OCR performs on the current anchor region.
If you modify the position or size of an anchor region on the document image, any Learning is removed.
Therefore, the next time learning is performed, the anchor region is enlarged.
Note: Modifying the position or size values in the Anchor Properties dialog
does not remove learning, so subsequent learning does not enlarge the anchor size.
