Input C/C++ Header

/** The tone mapping will leave unchanged (linear mapping) any pixels whose
 * brightness is strictly below this. The interpretation depends on
 * relative_to_max_display. If true, this is a ratio [0, 1] of the maximum
 * display brightness [nits], otherwise an absolute brightness [nits].
 */

Bindgen Invocation

bindgen::Builder::default()
    .header("input.h")
    .generate()
    .unwrap()
