There are many ways to build better apps with LEADTOOLS. We strive to give developers many options that fit their development style and environment. In addition to our Full Evaluation Download, the vast majority of our .NET functionality is available via NuGet. To help you start coding faster, we've compiled a list of source code projects that reference our NuGet packages.

All Projects (OCR, Barcode, Forms, Converter, Viewer, PACS)

This collection of projects includes all functionality available in LEADTOOLS NuGet packages. Springboard your development using these projects for OCR, Barcode, Document Viewing and Conversion, Forms Recognition, DICOM, PACS, and more for .NET Framework, .NET Core, UWP, Xamarin, and Web development.

OCR and Forms Projects

Includes projects to show accurate and extremely fast OCR and Forms Recognition and Processing technology that extracts text and data from images. OCR technology converts document images to text-searchable and editable formats such as PDF, PDF/A, DOC, DOCX, XML, and XPS. Supports character sets for more than 40 languages. Forms recognition and processing technology detects and processes unstructured and semi-structured documents such as bubble forms, invoices, applications/tax forms, checks, passports, driver's licenses, business cards, and credit cards. LEADTOOLS Forms uses an advanced combination of OCR, OMR, ICR, barcode, and intelligent image processing techniques, image cleanup and more to automate the extraction of text from complex documents.

Barcode Projects

Includes projects and sample images for detecting, reading, and writing barcodes such as UPC, EAN, Code 128, QR Code, Data Matrix, PDF417, and more for .NET Framework, .NET Core, UWP, and Xamarin development

Document Converter Projects

Includes projects that convert to and from any document or raster image file and perform document-to-document conversion at 100% accuracy without the need for OCR for .NET Framework, .NET Core, UWP, and Xamarin development.

Document Viewer (.NET) Projects

Includes projects that show how to use the .NET LEADTOOLS Document Viewer create robust, fully featured applications with rich document-viewing features, including text search, annotation, memory-efficient paging, inertial scrolling, and vector display in WinForms and WPF UIs.

Document Viewer (HTML5/JavaScript) Projects

These fully functional and OEM-ready web application projects include ASP.NET Web API services and rich HTML5/JavaScript client side technology to create robust, fully featured applications with rich document-viewing features, including text search, annotation, memory-efficient paging, inertial scrolling, and vector display. The web version of the Document Viewer also includes the Document Composer, Document Comparer, and integration with popular 3rd-party cloud storage services including SharePoint, OneDrive, and Google Drive.

Medical PACS Projects

This collection of projects demonstrates how to use LEADTOOLS PACS libraries to create advanced Medical Imaging applications with .NET Framework. It also includes the Zero-footprint, HTML5/JavaScript Medical Web Viewer web application, which is an OEM-ready, platform-independent solution for displaying DICOM studies for all medical disciplines and modalities.

NOTE: LEADTOOLS requires a license file, even for the free evaluation. When you click the downloads above, you will be directed to our standard evaluation form. After filling out the short survey, you will be emailed an evaluation license file and your download will begin.

Choose an Evaluation License

LEADTOOLS requires a license file, even for evaluation. You can either download and install the full evaluation, or get a limited license paired with your NuGet package.

The recommended way to receive a license file is to download the Full Evaluation, which includes all LEADTOOLS Recognition, Document, Medical, Vector, and Imaging libraries for all development and target platforms. The license file included with the Full Evaluation Download is a 60-day full license with no watermarking.

Alternatively, if you only want to download and evaluate our NuGet packages, you can receive a 30-day, limited license file that will randomly watermark your images and documents.
