Document Framework

Provides the core libraries for creating, loading, saving, viewing, converting, and signing documents. This gives developers a base for adding document handling features directly into applications that work with business content, scanned files, and image-based documents.

PDF Viewing Support

Includes PDF viewing capabilities for applications that need to render and inspect PDF content. It supports document-centric interfaces where users open, review, and navigate PDF files alongside other supported document and image formats.

Image Annotation And Markup

Adds annotation and markup features for image-based workflows. Applications can present images for review and allow users to place visual notes and markups where document review, feedback, and redaction-style preparation are part of the process.

Bitonal Image Display

Supports specialized bitonal image display with performance and memory optimizations. This is useful for high-volume document imaging scenarios that rely on black-and-white scanned pages and need responsive rendering without excessive resource use.

Document Image Cleanup

Includes cleanup functions for document images, including inverted text, border removal, hole-punch removal, and line removal. These functions help prepare scanned pages for clearer viewing, cleaner storage, and better downstream processing in document workflows.

Scanning And Acquisition

Supports scanning with LEADTOOLS Fast TWAIN and WIA. This allows applications to acquire pages directly from compatible devices and bring scanned content into imaging and document workflows without relying on separate capture software.

Image Processing Functions

Provides image processing, image segmentation, and common imaging dialogs for working with document images and raster content. Developers can use these capabilities to adjust, enhance, and prepare images before display, storage, conversion, or additional processing.

Format Conversion And Compression

Loads, saves, and converts more than 165 raster image and document formats, and supports a wide range of compression and decompression methods. It also includes metadata handling, SVG and EMF creation and conversion, and mixed raster content support.

Document Writers

Includes document writer functionality for creating output files, including searchable, XPS, and DOCX formats. This helps applications generate finished documents from processed images, pages, annotations, and other compiled content inside the same SDK.
