突出顯示 PDF 檔中的關鍵內容

Highlight text annotation in PDF WPF .NET controls is a feature that visually marks text with a colored overlay to draw attention to important content without modifying the original document. For software developers, it helps deliver clearer document review experiences by making key passages easier to identify, supporting user feedback and content emphasis, and improving readability and interaction in PDF-based business applications.

Several .NET WPF PDF components offer highlight text annotation including:

• Telerik UI for WPF PdfProcessing (part of Telerik UI for WPF) lets you create text markup annotations that highlight important PDF passages for clearer review.
• ImageGear for .NET by Accusoft lets you add highlight markup in WPF PDF applications, supporting visual review, annotation workflows, and document collaboration.
• XFINIUM.PDF WPF Edition facilitates adding, editing, removing, and flattening highlight annotations, giving developers flexible control over PDF review scenarios directly.
• Syncfusion WPF PDF (part of Syncfusion Essential Studio Enterprise) allows you to add, customize, and track highlight annotations, including color, opacity and author details.
