Edge Adjustment

Provides a configurable mechanism for adjusting the edges of a region during Geometric section extraction.

Remarks

Use Edge Adjustments to fine-tune the boundaries of a region extracted from a document. Adjustments can be applied to any edge (left, top, right, or bottom) and may be based on anchors, page boundaries, or manual offsets.

How Edge Adjustments Work

• Each edge of a region can be independently adjusted using one or more strategies.
• Adjustments are typically performed after the initial region is established by a main extractor.
• The adjustment process may include:
  • Locating text anchors or other features to align the edge.
  • Applying a manual offset using the 'Manual Adjustment' property.

Edge adjustments are essential for scenarios where the initial extraction region does not precisely match the desired content boundaries, such as when content is variably positioned or when additional whitespace or artifacts need to be excluded or included.

> Tip:
> Combine multiple Edge Adjustments for complex extraction requirements, such as aligning to both text anchors and applying a fixed offset.

Properties

Name	Type		Description
Manual Adjustment	String	►	Specifies a manual offset to apply to the edge, after all other adjustments are complete. ConverterSimple Value Converter The value of 'Manual Adjustment' is interpreted as a distance in document units (such as inches or millimeters, depending on configuration). Positive values move the edge outward (expanding the region). Negative values move the edge inward (shrinking the region). This property is useful for fine-tuning the final position of an edge, especially when automatic adjustments do not yield the exact desired result. > Example: > To move the left edge 0.1 inches to the right, set 'Manual Adjustment' to -0.1.

Derived Types

There are 4 implementations of Edge Adjustment.

Absolute	Adjusts a region edge to a specific absolute position on the page.
Anchor	Adjusts a region edge relative to a text anchor found in the document.
Edge of Page	Adjusts a region edge to the full bounds of the page.
Relative	Adjusts a region edge by a fixed distance, relative to its current position.
