Function JxlEncoderUseContainer 

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

Forces the encoder to use the box-based container format (BMFF) even when not necessary.

When using JxlEncoderUseBoxes, JxlEncoderStoreJPEGMetadata or JxlEncoderSetCodestreamLevel with level 10, the encoder will automatically also use the container format, it is not necessary to use JxlEncoderUseContainer for those use cases.

By default this setting is disabled.

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

Parameters

• enc: encoder object.
• use_container: true if the encoder should always output the JPEG XL container format, false to only output it when necessary.

Returns

• JxlEncoderStatus::Success if the operation was successful.
• JxlEncoderStatus::Error otherwise.
