HDR I/O

inline Image<RGB> huira::read_image_hdr(const fs::path &filepath)

Reads a Radiance HDR file and returns linear RGB data.

Convenience overload that reads the file into memory and forwards to the buffer-based implementation.

Parameters:

filepath – Path to the HDR file to read

Returns:

The linear RGB image.

inline Image<RGB> huira::read_image_hdr(const unsigned char *data, std::size_t size)

Reads a Radiance HDR from an in-memory buffer and returns linear RGB data.

HDR files natively store linear radiance values using RGBE encoding, so no gamma conversion is needed. HDR does not support alpha channels.

Parameters:

• data – Pointer to the HDR data in memory

• size – Size of the data in bytes

Returns:

The linear RGB image.

inline Image<float> huira::read_image_hdr_mono(const fs::path &filepath)

Reads a Radiance HDR file and returns linear mono data.

Convenience overload that reads the file into memory and forwards to the buffer-based implementation.

Parameters:

filepath – Path to the HDR file to read

Returns:

The linear mono image.

inline Image<float> huira::read_image_hdr_mono(const unsigned char *data, std::size_t size)

Reads a Radiance HDR from an in-memory buffer and returns linear mono data.

RGB channels are averaged to produce mono output.

Parameters:

• data – Pointer to the HDR data in memory

• size – Size of the data in bytes

Returns:

The linear mono image.
