Function JxlEncoderStoreJPEGMetadata 

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

Configure the encoder to store JPEG reconstruction metadata in the JPEG XL container.

If this is set to true and a single JPEG frame is added, it will be possible to losslessly reconstruct the JPEG codestream.

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

Parameters

• enc: encoder object.
• store_jpeg_metadata: true if the encoder should store JPEG metadata.

Returns

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