High-level HDF5 APIsThe HDF5 Library includes several sets of convenience and standard-use APIs. The HDF5 Lite APIs are convenience functions designed to facilitate common HDF5 operations. The HDF5 Image, HDF5 Table and HDF5 Packet Table APIs implement standardized approaches to common use cases with the intention of improving interoperability. |
|||
Lite | The H5LT API general higher-level functions | ||
Image | The H5IM API for images | ||
Table | The H5TB API for manipulating table datasets | ||
Packet Table | The H5PT API for managing packet tables
(and the C++ H5PT wrappers) |
||
Dimension Scales | The H5DS API for managing dimension scales | ||
Optimized Functions | Specialized HDF5 performance-optimized functions, generally requiring careful setup and testing | ||
Extensions | High-level HDF5 functions for working with region references, simple hyperslabs, and bitfields. | ||
Main HDF5 Library, or Low-level APIsThe main HDF5 Library includes all of the low-level APIs, providing user applications with fine-grain control of HDF5 functionality. |
