Starting image address/ | The host application must always seed the scanner with the starting | ||||||||||
next image address | image address. The scanner will return the image address associated | ||||||||||
| with each image in the image header. The application can track this | ||||||||||
| image address for use in setting the next image address when | ||||||||||
| restarting the scanner. | ||||||||||
Indexing schemes | Documents are scanned to record the information in an easily | ||||||||||
| accessible form. The scanner offers the following indexing schemes: | ||||||||||
| • | Single level |
|
|
|
| |||||
| • | Two level |
|
|
|
| |||||
| • | Two level offset | |||||||||
| • | Three level |
|
|
|
| |||||
| • | Three level offset | |||||||||
| Single level indexing | ||||||||||
| When using single level indexing, the image address assigned to each | ||||||||||
| document is defined as follows: | ||||||||||
| • Field D is defined as a Level 1 field having a field length greater than | ||||||||||
|
| 0. |
|
|
|
|
|
|
|
| |
|
| For example, if you scan a book with 50 pages and do not want a | |||||||||
|
| fixed field in the image address, the image address is defined as | |||||||||
|
| follows: |
|
|
|
| |||||
| • | Field D has a field length of 2 characters and is defined as a Level 1 | |||||||||
|
| field. |
|
|
|
| |||||
| • | Fields A, B and C have 0 characters. | |||||||||
