Extrahieren von Text aus gescannten PDFs

Juni 23, 2026
Aspose.PDF for .NET V26.6 integriert die Möglichkeit, gescannte Dokumente in durchsuchbare, zugängliche Texte umzuwandeln, ohne auf separate OCR-Tools angewiesen zu sein.

Aspose.PDF for .NET enables developers to seamlessly integrate PDF generation, manipulation, and conversion functionalities within their applications. It eliminates the dependency on Adobe Acrobat by providing a programmatic interface for working with PDF documents, allowing for tasks like creating PDFs from scratch, editing existing ones, adding elements like images and watermarks, and managing security features.

The Aspose.PDF for .NET V26.6 release introduces Integrated Optical Character Recognition (OCR) for PDF Text Recognition, allowing developers to extract text directly from scanned PDFs and image-based documents through the same API. This enhancement simplifies workflows by removing the need to integrate and maintain separate OCR solutions, reducing development complexity and deployment overhead. By making previously inaccessible content searchable, editable, and available for data extraction, the feature helps improve document accessibility, supports compliance requirements, and enables more effective document indexing and archiving. For organizations processing large volumes of scanned documents, the integrated OCR capability can improve productivity while providing a more consistent and streamlined document processing experience.

PDF Xpansion SDK 18.0.2 integriert eine vollständige SVG-Importfunktion, die es ermöglicht, fortschrittliche moderne Vektorgrafiken direkt in PDF-Dokumente einzubetten.

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.

To see a full list of what's new in 18.0.2, see our release notes.

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.
