Capture contenido PDF a través del visor

Extracting content using a PDF Viewer refers to enabling end users or applications to select and retrieve content directly through the viewer’s user interface, based on interactive actions such as text selection, area selection, or page-level capture. For software developers, this means the viewer acts not only as a rendering surface but also as a controlled extraction layer that exposes selected text, images, or regions. This approach is valuable in review, approval, and data capture scenarios because it reflects explicit user intent, aligns extracted data with what is visibly selected on screen, and avoids reliance on background parsing alone, resulting in more predictable and user-driven content retrieval within applications.

Several WinForms PDF Viewer components allow content extraction, including:

• DevExpress WinForms PDF Viewer (part of DevExpress WinForms) allows you to extract user-selected text and visual regions directly through the PDF viewer.
• Telerik UI for WinForms PDF Viewer (part of Telerik UI for WinForms) allows you to capture visually selected PDF content in the viewer, returning text aligned with user interactions.
• PDFView4NET Windows Forms Edition by PDF4DEV Solutions facilitates extracting text, images, and regions directly from its PDF viewer based on  user selections.
• Syncfusion WinForms PDF Viewer (part of Syncfusion Essential Studio Enterprise) lets you retrieve user-selected PDF text and areas via the viewer.
