    Enum BarcodeImageCorrection

    Specify the amount of pre-processing to clean pixels in noisy input documents. Useful for scans and photographs that may have visual noise obstruction. Internally, this process aims to separate dark barcode pixels from background patterns in images.

    Please understand that pre-processing is CPU-heavy and we recommend experimenting with different settings starting with the lowest settings first and gradually working up from there.
