PDF Xpansion SDK 18.0.2 添加完整 SVG 匯入功能，使進階向量圖形能直接嵌入 PDF 文件中。

PDF Xpansion SDK by soft Xpansion is a modular software development kit for Windows applications that provides a broad set of APIs and components for creating, editing, viewing, converting, validating, and processing PDF, PDF/A, and XPS documents, alongside support for modern electronic invoicing standards such as XRechnung, ZUGFeRD, Factur-X, and EN 16931. The SDK includes specialized modules for PDF viewing, document combination and splitting, PDF/A compliance, and e-invoicing creation and receipt workflows, enabling developers to integrate document management, archiving, compliance, and business process functionality directly into desktop and enterprise applications. It also supports advanced capabilities such as PDF/UA accessibility, embedded XML data, document conversion, structured invoice validation, and customizable viewing interfaces, allowing developers to build solutions for document-centric workflows, digital archiving, regulatory compliance, document viewing, and automated invoice processing using a common set of PDF and e-invoicing development components.

The PDF Xpansion SDK 18.0.2 update introduces full SVG import capability, allowing developers to embed complete SVG files directly into PDF documents rather than being limited to basic SVG elements. This enhancement improves fidelity when working with vector graphics by preserving complex shapes, gradients, paths, and other advanced SVG features during PDF generation. As a result, applications can produce more accurate and visually consistent PDF output from modern SVG-based assets, reducing the need for graphic simplification, conversion workarounds, or manual adjustments while supporting a broader range of design and reporting scenarios. Note: This feature is not included in the license and requires an additional purchase - details and pricing available upon request.

PDF Xpansion SDK products are licensed on a per-location basis, with a separate license required for each company location where developers use the SDKs. An annual maintenance subscription is also available, providing product updates and 12 man-hours of support for one year. Optional add-ons are available, and certain features not included in the standard license may be licensed separately for an additional fee.

在為受信任使用者提供受控訪問的同時，加密和解密 PDF 以嚴格保護敏感文件。

Encrypting and decrypting PDF files allows developers to secure sensitive documents with strong encryption while enabling authorized users to safely access protected content when needed. By applying password protection and access controls, organizations can prevent unauthorized viewing or sharing of confidential information such as legal contracts, financial reports, healthcare records, and proprietary research while supporting secure document workflows and compliance requirements.

Several .NET PDF controls offer encryption and decryption support including:

  • DevExpress PDF Document API for .NET (part of DevExpress Office File API) lets you encrypt and decrypt PDF documents to securely protect sensitive information.
  • Aspose.PDF for .NET allows you to apply PDF encryption and decryption for secure document sharing, controlled access, and compliance support.
  • IronPDF for .NET by Iron Software facilitates secure PDF encryption and decryption that help protect confidential files from unauthorized viewing or distribution.
  • PDF4NET by PDF4DEV Solutions lets you encrypt and decrypt PDF documents while managing secure access to sensitive reports, contracts, and proprietary business content.

添加內置 PDF 操作工具，無需依賴外部軟體即可合併、拆分、壓縮和重組文件。

PDF manipulation allow applications to create, modify, and manage PDF documents programmatically or through integrated user interfaces. These features support a wide range of document workflows, from reorganizing pages to extracting information and optimizing file sizes. By incorporating PDF manipulation tools directly into applications, developers can support more efficient document processing without relying on external software.

Common features include:

  • Compressing PDFs which reduces file sizes to make documents easier to store, transfer, and share while maintaining acceptable visual quality.
  • Deleting pages from a PDF enables users to remove unnecessary or sensitive content from existing documents.
  • Adding pages to a PDF allows new pages to be inserted into documents to expand or reorganise content.
  • Merging PDFs combines multiple PDF files into a single document, simplifying document management and distribution.
  • Splitting PDFs separates a document into smaller files, helping users isolate sections or distribute content more efficiently.
  • Extracting content allows users to retrieve text, images, or other embedded information from PDFs for reuse, analysis, or indexing purposes.
  • Managing metadata provides tools for viewing and updating document properties such as author details, titles, keywords, and creation dates.

在 WinForms 中啟用可靠的 PDF 列印

在您將 PDF 列印到帶有內置檢視器控制項或開發者驅動 API 集成的印表機時，保持文件的一致性。

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.
