.NETアプリでPDFを画像に変換

3月 30, 2026
プレビュー、共有、レポート作成、画像ベースのワークフロー向けに、.NETアプリケーションでPDFページを画像としてレンダリング可能

PDF to image conversion support in a PDF viewer component refers to the ability to render one or more pages of a PDF document as raster images, such as PNG or JPEG, directly within the application or for export. This capability is typically built on top of the viewer’s rendering engine and allows developers to generate visual representations of document content. It is useful for scenarios such as generating thumbnails, enabling previews in environments where PDF rendering is not supported, simplifying content sharing, or integrating with image-based processes like OCR (optical character recognition) and reporting.

Several .NET PDF Viewer controls allow you to convert a PDF to an image including:

  • Document Solutions for PDF by MESCIUS allows you to convert PDF pages into high-quality images within its viewer, supporting thumbnails, previews, and export scenarios.
  • Telerik UI for WinForms PDF Viewer (part of Telerik UI for WinForms) lets you render PDF pages as images, enabling efficient previews, and visual content reuse.
  • XFINIUM.PDF CROSS PLATFORM EDITION facilitates PDF to image conversion within its viewer, producing consistent raster outputs for previews and reporting.
  • WPViewPDF by WPCubed allows you to generate image representations of PDF pages inside its viewer component, supporting compatibility with image-based processing.

WPFでプログラム的にPDFを作成

3月 27, 2026
WPFアプリケーションがコードから直接PDFを作成し、ドキュメント構造、レイアウト、コンテンツレンダリングを正確に制御可能

Creating PDFs programmatically involves generating Portable Document Format files from application data, user input, or existing content such as text, images, or HTML. Developers implementing this capability allow the production of consistent, platform-independent documents that preserve layout and formatting across devices. It is widely used for reporting, document archiving, invoicing, and content distribution, offering benefits such as precise control over document structure, automation of document workflows, and the ability to integrate document generation directly into applications.

Several WPF PDF components allow you to create PDFs, including:

  • ComponentOne WPF PDF (part of ComponentOne Studio WPF by MESCIUS) provides a .NET API for programmatically creating PDF documents in WPF applications.
  • Telerik UI for WPF PdfProcessing (part of Telerik UI for WPF) includes a framework-independent library for generating PDF files programmatically from scratch.
  • IronPDF for .NET by Iron Software also supports WPF and provides the ability to generate PDF documents by rendering HTML, URLs, or other existing content into PDF format.
  • Syncfusion WPF PDF (part of Syncfusion Essential Studio Enterprise) includes a WPF PDF library for creating, modifying, and saving PDF documents with layout control.

ゲージビジュアルで報告を強化

3月 26, 2026
レポートにゲージを追加することで、複雑なデータを簡素化し、目標に対するパフォーマンスを強調する明確でリアルタイムの視覚的洞察を提供

Adding gauges to reports means incorporating visual indicators such as dial or meter style graphics that display key metrics against defined ranges or targets, making performance instantly understandable at a glance. This approach enhances report clarity by transforming complex or dense data into intuitive visuals, helping users quickly assess whether values fall within acceptable, warning, or critical thresholds. As a result, gauges support faster, more informed decision making, improve stakeholder communication, and create more engaging, user friendly reports. Common use cases include tracking sales performance against quotas, monitoring system health or uptime, visualizing budget utilization, and displaying KPI progress in executive dashboards where quick insights are essential.

Several .NET WPF Reporting controls include Gauges including:

  • DevExpress Reporting lets you embed customizable gauge controls in reports to visualize KPIs, enabling clear performance tracking and faster data driven decisions.
  • Telerik Reporting allows you to incorporate interactive gauges into reports, presenting real time metrics with intuitive visuals that enhance clarity and user engagement.
  • List & Label Enterprise Reporting Edition by combit facilitates adding gauge elements to reports, helping users highlight key values, thresholds, and performance trends effectively.
  • Stimulsoft Reports.WPF enables you to design rich reports with gauge components, delivering precise visual feedback on metrics for improved monitoring and analysis.
