Ative a anotação de PDF em Apps WinForms

Dezembro 19, 2025
Visualizadores de PDF com ferramentas de anotação integradas permitem que os usuários revisem, comentem e colaborem em documentos sem modificar o conteúdo 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.

Dezembro 19, 2025
Ative a edição de imagem no app para WPF com anotação, corte, transformações, zoom, desfazer e refazer, além de importação e exportação simples.

Image editing in a data editor component helps users work with images alongside other data fields. This includes basic functions like cropping, rotating, resizing, and adding annotations. It's useful for tasks such as cleaning up user-uploaded files, adjusting product photos, or marking up visual references—all without switching to another application. This keeps image handling part of the same process as your data updates.

Several .NET data editor collections provide an image editor, including:

  • DevExpress WPF Data Editors (part of DevExpress WPF) lets you embed image editing within forms, enabling cropping, annotation and validation.
  • Telerik UI for WPF Data Editors (part of Telerik UI for WPF) allows you to integrate image modification tools into business apps, supporting annotations and transformations.
  • Syncfusion WPF Data Editors (part of Syncfusion Essential Studio Enterprise) facilitates image editing in data driven interfaces, enabling adjustments and visual annotations.
