A text search feature in a PDF component allows developers to programmatically locate specific words or phrases within a PDF document. This functionality typically supports options such as case sensitivity, whole word matching, and navigation between search results. It is particularly useful in applications where users need to quickly identify and interact with relevant content in large or complex documents. By enabling this feature, developers can enhance the user experience in document viewing or editing environments, reduce manual search effort, and support features like text highlighting, annotation, or content extraction for further processing.

Ellipse annotations in PDF viewer components are shape‑based markups that allow users to draw oval or circular outlines (or filled ellipses) on PDF pages. Such annotations are valuable in highlighting regions, drawing attention to content, or visually marking up documents for review without altering the underlying text. They generally include settings for border color, line width, fill color or transparency, and may offer popup notes, captions, or comments associated with the ellipse shape. The feature supports both interactive use and programmatic control in many viewers.

  • Document Solutions for PDF by MESCIUS provides a CircleAnnotation class allowing users to place an ellipse on a page and configure its position.
  • Syncfusion PDF Viewer (part of Syncfusion Essential Studio Enterprise) supports ellipse shape annotations and customize stroke and fill color, thickness and opacity.
  • PrizmDoc Viewer by Accusoft allows users to draw, edit, or delete ellipse annotations, add comments, and control the display settings of those annotations.
