Capture contenido PDF a través del visor

Diciembre 30, 2025

Habilite aplicaciones para extraer texto y regiones seleccionados por el usuario directamente de documentos PDF, alineando los datos recuperados con interacciones visibles en pantalla.

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.

Mejore la claridad de los gráficos circulares con etiquetas alineadas lateralmente

Diciembre 29, 2025

ComponentOne Studio WinForms 2025 v2 mejora FlexPie con etiquetas alineadas lateralmente para permitir materiales visuales más limpios y una mejor legibilidad.

ComponentOne Studio WinForms by MESCIUS is a comprehensive toolkit offering over 120 advanced UI components to improve Windows Forms application development. It helps you to build visually appealing and feature-rich applications with functionalities like data visualization through charts and reports, intuitive data editing with performant grids, and modern UI elements including ribbons and docking for a user-friendly experience.

The ComponentOne Studio WinForms 2025 v2 update introduces a new data label placement option for FlexPie that aligns labels along the left and right sides of the chart to improve readability and visual structure. By moving labels out of the pie area, this option reduces overlap and congestion when working with datasets that contain many slices or small values, which are common challenges in pie chart rendering. The result is a more consistent and predictable layout that helps developers present data more clearly while maintaining a clean, modern appearance across different screen sizes and data scenarios.

ComponentOne Studio WinForms is licensed per developer on a perpetual basis and includes a 12 month subscription. Priority Support is also available. See our ComponentOne Studio WinForms licensing page for full details.

Habilite anotación de PDF en aplicaciones WinForms

Diciembre 19, 2025

Los visores de PDF con herramientas de anotación integradas permiten a los usuarios revisar, comentar y colaborar en documentos sin modificar el contenido original.

PDF annotation in .NET WinForms PDF viewer components refers to the ability to add visual and textual markup directly onto PDF documents without altering the original content. These tools allow users to draw shapes, highlight text, insert comments, and place notes within the viewing interface, supporting workflows such as document review, feedback, and approval. This functionality improves collaboration and clarity in document handling, making it well-suited for document processing tasks in WinForms applications.

Common features include:

Freehand Draw (Ink Annotation) allows users to sketch, underline, or handwrite directly on the page using a mouse, stylus, or touch input, making it ideal for markups and signatures.
Lines provide a simple way to connect points or emphasize linear elements within a document, often with configurable thickness, color, and opacity.
Rectangles enable users to highlight or frame areas of interest, supporting both outlined and filled styles for visual emphasis.
Ellipses offer a similar highlighting function to rectangles but with a rounded shape, useful for circling content or marking irregular regions.
Arrows are commonly used to direct attention to specific content, combining line styling with arrowheads to clearly indicate focus or flow.
Sticky Note annotations allow users to attach comments to precise locations in the document, typically displayed as icons that reveal text on interaction.
Free Text enables direct placement of typed text onto the page with control over font, size, color, and alignment, supporting clear, visible commentary without pop-ups.
