| Description: |
Overscan is used to scan outside of the boundaries described by
ICAP_FRAMES, and is used to help acquire image data that may be lost because of skewing.
This is primarily of use for transport scanners which rely on edge detection to begin scanning. If overscan is supported, then the device is capable of scanning in the inter-document gap to get the skewed image information.
|
| Remarks: |
Use this capability, if available, to help software processing images for deskew and border removal.
