Anchor Editor

Editor for defining an anchor (a reference point relative to a text element on the document).

Remarks

Overview

The Anchor Editor control provides an interactive interface for configuring anchor locations within a document. Anchors are reference points used to position, align, or extract data relative to text or visual elements. This editor is commonly used in extraction, layout, and document design scenarios where precise positioning is required.

UI Components

• Anchor Property Grid:
  • Displays editable properties for the anchor, such as coordinates, dimensions, and alignment options.
  • Supports inline editing, validation, and contextual help.
• Test Source:
  • Allows users to select or preview a test batch or document source for anchor validation.
  • Useful for verifying anchor placement and behavior against real document samples.
• Document Viewer:
  • Renders the document and visually displays the anchor location.
  • Supports zoom, pan, and overlay features to inspect anchor placement.
  • May allow interactive adjustment of anchor position via drag-and-drop or direct input.

Interactive Features

• Anchor Configuration:
  • Edit anchor properties using the property grid.
  • Visualize anchor location in the document viewer.
  • Test anchor behavior against sample documents using the test source.
• Keyboard Navigation:
  • Tab: Move between input fields and controls.
  • Enter: Commit changes or activate selected controls.
  • Arrow Keys: Adjust anchor position (if supported).
• Mouse Operations:
  • Drag anchor overlay to reposition.
  • Click to select or edit anchor properties.

Usage Guidance

Use the Anchor Editor to define and validate anchor points for extraction, layout, or alignment tasks. Configure anchor properties in the grid, preview placement in the document viewer, and test against sample sources to ensure accuracy.

• For extraction scenarios, anchors help locate fields, labels, or regions relative to document content.
• In layout design, anchors support precise positioning of elements for rendering or export.
• Use the test source and viewer to validate anchor configuration before applying to production documents.

Accessibility

• Fully navigable by keyboard and mouse.
• Screen reader support for property grid, viewer, and controls.
• Visual cues for selection, focus, and anchor placement.
