binarization
Filter to apply to the input image when adding pages with binarization. If set, the filter is applied to the input image and the resulting image is stored as a 1-bit TIFF. When storing documents it's typically best to use the BINARY_DOCUMENT_OPTIMIZED_COMPRESSION compression mode (CCITT_T6) instead of the default, as it tends to produce the smallest file sizes. If not set, simple thresholding is applied to the image, instead.
