OpenImageIO

OpenImageIO (OIIO) is a high-performance, open-source library and toolset for reading, writing, and processing images in a wide variety of file formats, using a format-agnostic API. Primarily aimed at visual effects (VFX) and animation applications, it provides robust support for formats like OpenEXR, TIFF, JPEG, PNG, and many more. The library is actively maintained by the Academy Software Foundation, with frequent minor releases within its major versions.
