在 .NET 应用中将 PDF 转换为图像

3月 30, 2026
在 .NET 应用程序中将 PDF页面渲染为图像，用于预览、分享、报表和基于图像的工作流程。

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.

以编程方式在 WPF 中生成 PDF

3月 27, 2026
允许 WPF 应用程序直接从代码创建 PDF，精确控制文档结构、布局和内容渲染。

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.

捕捉 PDF 中的自由手写墨迹注释

3月 26, 2026
创建支持手写注解的应用程序，允许用户直接用触控笔、触摸或鼠标注释文档。

Freehand ink annotation support in a PDF component enables applications to capture and render freehand drawings directly on a PDF document, typically using input from a mouse, stylus, or touch device. It allows users to write, sketch, highlight, or mark up content in a natural way, with the annotations stored as standard PDF ink annotations that remain part of the document. For software developers, this capability adds interactive review and collaboration features to applications such as document viewers and form-processing systems, allowing users to provide visual feedback, sign documents, or annotate content without altering the original PDF structure.

Several .NET PDF components feature support for freehand ink annotations including:

  • Document Solutions for PDF (by MESCIUS) allows you to record freehand ink strokes and store them as standard PDF annotations for review scenarios.
  • DevExpress PDF Document API for .NET (part of DevExpress Office File API) lets you create, edit, and flatten Ink annotations for freehand PDF markup workflows.
  • PDF4NET (by PDF4DEV Solutions) facilitates drawing and preserving freehand ink annotations in PDFs, supporting stylus and touch input.
  • Syncfusion ASP.NET Core PDF (part of Syncfusion Essential Studio Enterprise) enables developers to capture and render freehand ink annotations in PDFs.

在 .NET 中启用 PDF 向 Word 的转换

3月 13, 2026
为 .NET 应用程序提供将 PDF 文档转换为 Microsoft Word 格式（如 DOC 和 DOCX）的功能。

PDF to Word conversion is the process of transforming a Portable Document Format (PDF) file into an editable Microsoft Word document such as DOC or DOCX. This capability is widely used when content that was originally distributed in a fixed-layout format needs to be modified, reused, or incorporated into other documents. Converting PDFs to Word allows users to edit text, adjust formatting, and extract tables or images without manually recreating the original content. For developers and organizations that process large volumes of documents, automated conversion can improve productivity by enabling document reuse, simplifying content updates, and supporting processes that require editable formats.

Several .NET PDF components allow you to convert PDF to Word, including:

  • DevExpress PDF Document API for .NET (part of DevExpress Office File API) can extract text and images from PDF files, which can then be used to generate Word documents.
  • Aspose.PDF for .NET provides built-in functionality for converting PDF files directly to Microsoft Word formats such as DOC and DOCX.
  • GroupDocs.Conversion for .NET includes native support for converting PDF documents to Word formats including DOC, DOCX, and RTF.
