Image addressing | Unlike previous |
| Scanners moved all image address functionality to the host. This |
| includes index format, starting image address, image address format |
| and level rules. |
Image address format | The image address format can be from one to four fields. Each field |
| may be up to 9 characters. Total image address length with delimiters |
| is 30 characters. Each field may use level 1, level 2, level 3, and fixed |
| fields, and must be explicitly defined by the application. Image address |
| format is flexible and includes the ability to define four fixed fields. See |
| Chapter 3 or 4 (depending on your driver) for more information. |
| The order of importance for the fields (from highest to lowest) is |
| fixed, level 3, level 2, level 1. When defining an image address, |
| the field with the highest importance must always be to the left. |
| For example, F321 is a valid format. F123 is not a valid format. |
| You are not required to use all four fields. If you chose to use |
| fewer than four fields, you must specify a field width of 0 for any |
| unused field. 0 width fields may not be between two |
| width fields. |
| When defining fields, you can only have one field assigned to |
| each individual level. For example, FF21 is a valid format. FF11 |
| is not a valid format. |
| When defining more than one fixed field the fixed field values |
| must be to the left of any index value. Fixed fields may not be |
| between level fields. For example, FFF1 is a valid format. FF1F |
| is not a valid format. |
Starting image address/ | The host application must always seed the scanner with the starting |
next image address | image address. It is no longer controlled within the scanner. 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. |
