Fixed Region

Specifies the position and size of the region to extract, using Logical Rectangle syntax.

• The rectangle is defined in logical units (such as inches or millimeters) and mapped to the page during extraction.
• Use the zone editor to visually select or adjust the region on a sample page.
• If the bounds are empty, no region will be extracted.

Example: 0.5in, 1in, 2.5in, 1.5in (left, top, right, bottom)

Specifies which pages the region should be applied to.

• Accepts a single page number (e.g. 1), a range (e.g. 1-3), or a comma-separated list (e.g. 1,3,5).
• If left blank, the region applies to all pages.

This is useful for forms where the target area only appears on certain pages, or for multi-page documents where zones are needed in different locations on different pages.

Can be one of the following types:

When enabled, the region's edges are automatically adjusted to align with the nearest detected horizontal or vertical lines on the page.

This is especially useful for extracting data from structured documents such as forms or tables, where precise alignment with printed lines improves accuracy.
