Read and generate MaxiCode barcodes in your .NET applications across 100+ image formats, including PDF, TIFF, JPEG, and PNG. Configure encoding modes and module spacing for fixed-size matrix codes. Built-in error correction enables reading, even when portions of the symbol are damaged.
This SDK delivers accurate MaxiCode barcode recognition and generation for .NET applications. Process codes across 100+ image formats with configurable encoding modes, multi-symbol detection, and built-in ECC error correction for robust performance.
Note: Each MaxiCode symbol has a fixed size of 884 hexagonal modules arranged in 33 rows around a central finder pattern, with each row containing 29 or 30 modules.
Recognize and generate MaxiCode barcodes across 100+ image formats, including PDF, TIFF, JPEG, and PNG. Decode codes from black and white, grayscale, palletized, and color images — full-page or region-specific detection.
Returns the decoded string value and precise bounding box coordinates (top-left, top-right, bottom-left, bottom-right) for each recognized MaxiCode barcode, enabling accurate positioning and validation.
Built-in ECC error correction algorithm enables recognition of partially damaged symbols. Reed–Solomon error correction ensures robust decoding even in challenging real-world conditions with degraded print quality.
AnyCPU architecture supporting 32-bit and 64-bit environments. Multithreaded processing delivers scalable performance for high-volume MaxiCode operations across modern computing environments.

It was developed by United Parcel Service (UPS) and is primarily used in shipping and logistics for package tracking, sorting, and delivery optimization. Each MaxiCode symbol has a fixed size of 884 hexagonal modules arranged in 33 rows.
The SDK supports more than 100 image formats, including PDF, TIFF, JPEG, PNG, BMP, and GIF. It can decode MaxiCode barcodes from black and white, grayscale, palletized, and full-color images with full-page or region-specific detection capabilities.
Yes. The GdPicture.NET SDK can detect and decode multiple MaxiCode barcodes within a single image. It returns the count of detected barcodes and provides access to each barcode’s value and position coordinates individually.
Yes. The SDK includes built-in Reed–Solomon error correction capabilities that enable recognition of partially damaged MaxiCode symbols. This ensures robust decoding, even in challenging real-world conditions with degraded print quality or partial obstruction.
Yes. The GdPicture.NET MaxiCode SDK features AnyCPU architecture supporting both 32-bit and 64-bit environments. Multithreaded processing delivers scalable performance for high-volume barcode operations, making it suitable for enterprise-level applications.
Yes. GdPicture.NET is part of the Nutrient product suite, and the MaxiCode recognition technology is consistent across Nutrient’s desktop, web, and mobile SDKs, providing reliable postal and logistics barcode processing across platforms.
