WinFormsで信頼性の高いPDF印刷を有効化

PDFをプリンターに印刷する際は、ビューアコントロールや開発者主導のAPI連携機能を備えたドキュメントの忠実度を一貫して維持

Printing PDFs to a printer is the process of sending a Portable Document Format (PDF) file from an application to a physical or virtual printer while preserving its layout, fonts, and graphical fidelity. A PDF viewer control typically handles rendering and pagination, ensuring consistent output across devices and print environments. The main benefit is predictable, high-quality output, which is especially important for documents that require precise formatting. Modern PDF viewer components support printing either directly through built-in user interface elements such as a toolbar or print dialog, or programmatically through application code using API methods, giving developers flexibility in how printing capabilities are exposed and controlled within an application.

Several WinForms PDF Viewer components allow you to print PDFs to a printer, including:

  • DevExpress WinForms PDF Viewer (part of DevExpress WinForms) provides print commands via its toolbar and keyboard shortcuts, plus API-based printing.
  • ComponentOne WinForms FlexViewer (part of ComponentOne Studio WinForms by MESCIUS) includes a viewer interface with integrated print functionality for direct printing.
  • Telerik UI for WinForms PDF Viewer (part of Telerik UI for WinForms) supports printing through its viewer interface, including a print dialog accessible to end users.
  • Syncfusion WinForms PDF Viewer (part of Syncfusion Essential Studio Enterprise) offers a toolbar-based print option for end users and an API for programmatic printing.

ブックマークでPDFをより速くナビゲート

構造化されたツリーベースのナビゲーションを提供し、ユーザーが関連するセクションに直接ジャンプし、文書とより効率的にやり取り可能

Bookmark navigation in a PDF Viewer enables developers to expose the hierarchical bookmark structure embedded within a PDF so users can quickly jump to specific sections or pages. It typically presents bookmarks in a tree view synchronized with the document, allowing programmatic control and event handling for selection changes. This capability improves usability in applications that handle large or structured documents by reducing manual scrolling, supporting faster content discovery, and providing a more organized reading experience.

より明確なフィードバックのためにPDF内注釈を有効化

4月 21, 2026
ユーザーがドキュメント内にメモ、ハイライト、視覚的マーカーを直接追加でき、フィードバックをわかりやすくして一箇所でアクセス可能。

Annotation capabilities in PDF Viewer components allow users to interact with documents through visual and textual markup, supporting review, collaboration, and documentation processes. Tools such as Line, Rectangle, and Free text help highlight structure and add clarity, while Sticky note and Stamp annotations provide contextual feedback and status indicators. By embedding these capabilities directly into a viewer, applications can offer a cohesive experience for editing and reviewing PDFs without requiring external software.

Common annotations include:

  • Ellipse annotations offer a circular or oval shape tool for highlighting regions in a less rigid form than rectangular annotations.
  • Free text annotations let users insert editable text anywhere on the page for inline commentary or corrections.
  • Freehand draw (Ink) annotations enable natural, pen-like input for signatures, sketches, or handwritten notes.
  • Line annotations allow users to draw straight connectors or highlights between points, often used for pointing out relationships or alignment.
  • Rectangle annotations provide a way to frame areas of interest, making it useful for emphasizing sections of a page.
  • Stamp annotations apply predefined or custom labels, such as approval or review statuses, directly onto the document.
  • Sticky note annotations add comment markers that can store detailed feedback without cluttering the document visually.

PDFから機密データを削除

ASP.NET CoreアプリケーションでPDF編集機能を実装し、機密情報を保護し、機密データへのアクセスを防止

PDF redaction is the process of permanently removing sensitive or confidential information from a document so that it cannot be recovered or viewed. Unlike simple visual masking, true redaction deletes the underlying content, ensuring it is not accessible through copying, searching, or metadata extraction. This capability is essential for regulatory compliance, data protection, and secure document sharing, particularly in industries that handle personal, financial, or legal information.

Several ASP.NET Core PDF components allow you to redact PDFs, including:

  • Document Solutions for PDF by MESCIUS provides a .NET API that enables developers to define and apply redaction regions and permanently remove sensitive content from PDFs.
  • ImageGear for .NET by Accusoft includes redaction annotations allowing applications to mark and obscure confidential information within documents.
  • Syncfusion ASP.NET Core PDF (part of Syncfusion Essential Studio Enterprise) offers redaction support, with APIs to mark and remove sensitive text or images.

.NET WPF PDFアプリケーションで重要なテキストを、レビューやフィードバック、文書の読みやすさを支える明確な視覚的強調で際立たせる

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.
