gdspell

gdspell is an open-source spell-checking library designed to integrate with applications that use the GD graphics library to render text on images. It provides spell-check capabilities for strings used in image generation, enabling developers to identify misspelled words and propose corrections during content creation or post-processing. The project emphasizes a lightweight footprint suitable for embedding in image-processing pipelines and content-generation tools.

Features include support for multiple dictionaries and languages, a simple C API with bindings to other languages, and options for loading user dictionaries. It offers tokenization, word normalization, and compatibility with common dictionary formats. The library is designed to be platform-neutral, with portability across major operating systems and compilers used in graphic applications.

Architecture and approach: gdspell splits input into tokens, checks each token against an in-memory dictionary, and returns results that include misspelled words and a list of suggested corrections. It can be extended with custom dictionaries and can operate in batch mode or inline during image generation. The project aims to minimize external dependencies and to integrate smoothly with existing GD-based workflows.

Development and licensing: gdspell is maintained by a community of volunteers and released under an open-source license. The project provides documentation, example code, and release notes; contributions from users are welcome.
