Function JxlEncoderFrameSettingsSetOption 

pub unsafe extern "C-unwind" fn JxlEncoderFrameSettingsSetOption(
    frame_settings: *mut JxlEncoderFrameSettings,
    option: JxlEncoderFrameSettingId,
    value: i64,
) -> JxlEncoderStatus

Sets a frame-specific option of integer type to the encoder options. The JxlEncoderFrameSettingId argument determines which option is set.

Parameters

• frame_settings: set of options and metadata for this frame. Also includes reference to the encoder object.
• option: ID of the option to set.
• value: Integer value to set for this option.

Returns

• JxlEncoderStatus::Success if the operation was successful.
• JxlEncoderStatus::Error in case of an error, such as invalid or unknown option id, or invalid integer value for the given option. If an error is returned, the state of the JxlEncoderFrameSettings object is still valid and is the same as before this function was called.
