Function JxlEncoderUseBoxes 

pub unsafe extern "C-unwind" fn JxlEncoderUseBoxes(
    enc: *mut JxlEncoder,
) -> JxlEncoderStatus

Indicates the intention to add metadata boxes. This allows JxlEncoderAddBox to be used. When using this function, then it is required to use JxlEncoderCloseBoxes at the end.

By default the encoder assumes no metadata boxes will be added.

This setting can only be set at the beginning, before encoding starts.

Parameters

• enc: encoder object.
