losLab PDF Library – All In One PDF Developer Kit

AOMEI Flash Sale for Partners

With losLab PDF Library, developers can generate PDF documents on the fly perfect for automated reports, invoices, forms, and e-books. You gain complete control over content: draw vectors (lines, curves, shapes), embed complex layouts, place text with full Unicode and font subset support, integrate images (JPG, PNG, BMP, TIFF, EMF), and render barcodes all within your application’s user interface or server processes. The SDK includes tools for rasterizing PDF pages to images (PNG, JPG, BMP, WMF) for viewing or printing.

Editing capabilities are equally comprehensive: add/remove pages, manage layers, handle form fields (AcroForms and XFA), and embed JavaScript logic for rich interactive forms. Security is robust, with encryption up to AES‑256, permissions control, and digital signatures to ensure document integrity.

Designed for seamless integration in enterprise environments, workflows can automate document splitting, merging, page extraction, metadata updates, bookmarking, annotation, hyperlinking, and PDF linearization for fast web viewing. Direct disk streaming and large-file optimizations ensure smooth handling of extensive PDF documents without high memory usage.

🔑 Key Features

1. Programmatic PDF Creation : Build documents from the ground up with support for text, vectors, fonts, images, shapes, barcodes, and color control—ideal for dynamic content generation.

2. File Conversion & Rasterization : Convert images (JPG, BMP, PNG, TIFF) and vector graphics (WMF, EMF) into PDFs. Rasterize pages to standard image formats for previews or printing.

3. Full PDF Editing Tools : Insert, remove, reorder, extract, rotate, and crop pages, manage layers, update metadata, attach files, and control view preferences programmatically.

4. Interactive Form Support : Create and manipulate AcroForms and XFA forms; read/write form data; apply JavaScript to enable dynamic form behaviors; flatten forms when needed.

5. Security & Digital Signatures : Secure PDFs with RC4 and AES (128/256-bit) encryption, apply password protection, set permissions, and embed digital signatures to confirm document authenticity.

6. JavaScript Integration : Embed document-level or form-field JavaScript to automate behaviors such as validation, calculations, navigation, and bookmarks.

7. Annotations, Links & Bookmarks : Add hyperlinks, file actions, notes, free text annotations, and structured bookmarks to enhance document navigation and usability.

8. Compression & Color Management : Optimize files with font and image compression, manage RGB/CMYK/Grayscale colors, and support spot color separations and transparency.

9. Page-Level Operations : Extract single pages or ranges, split or merge documents, clone pages, and handle multi-page imposition tasks such as booklets.

10. Metadata & Document Structuring : Set or read document metadata, manage view settings, count pages, embed files, and support geospatial PDF tags and standards.

11. Barcode Generation : Embed various barcodes including Code 39, EAN-13, Code 128, PostNet—within documents for labels, tracking systems, and automation workflows.

12. Developer Utilities & Streaming : Work with files directly on disk to optimize large‑file performance, use error-reporting functions, file lists, and stream IO for web/server integration.
