class libxl.JxlGainMapBundle
extends Object

Gain map bundle This structure is used to serialize gain map data to and from an input buffer. It holds pointers to sections within the buffer, and different parts of the gain map data such as metadata, ICC profile data, and the gain map itself. The pointers in this structure do not take ownership of the memory they point to. Instead, they reference specific locations within the provided buffer. It is the caller's responsibility to ensure that the buffer remains valid and is not deallocated as long as these pointers are in use. The structure should be considered as providing a view into the buffer, not as an owner of the data.
