OpenImageIO is a library and collection of utilities for reading, writing and processing image files.
It is designed particularly for visual effects and animation pipelines, offering format-independent APIs with the scalability and robustness needed for production environments.
The software supports a wide range of still-image, texture, camera RAW and movie formats through a plugin-based architecture. It also provides high-performance image caching, texture lookups, image-processing functions and Python bindings.
This is free and open source software.
Key Features
- Format-independent APIs for reading and writing image files.
- Plugin-based support for TIFF, JPEG, JPEG XL, OpenEXR, PNG, WebP, AVIF, RAW and many other formats.
- oiiotool utility for image conversion and processing.
- Tools for inspecting, comparing and searching image metadata.
- Efficient image caching for working with very large collections of files.
- Filtered MIP-map texture lookups for rendering applications.
- ImageBuf and ImageBufAlgo interfaces for in-memory image manipulation.
- Python bindings for the major APIs.
- Designed for renderers, compositors, viewers and visual-effects pipelines.
