2023-06-26Add ResultMetadataType.ERRORS_CORRECTED and ERASURES_CORRECTED (#1657)Daniel Gredler41-53/+179
* Add ResultMetadataType.ERRORS_CORRECTED and ERASURES_CORRECTED (2D barcodes) * Maintain existing constructor on AztecDetectorResult * Maintain existing ReedSolomonDecoder.decode method
2023-06-24Make OneDimensionalCodeWriter.encode(content, hints) public (#1659)primo-ppcg2-2/+2
This method is useful for encoding Code128 with a specific code set to a bool array. As no other class overrides this method, this change only affects Code128Writer. I don't know that there's a strong argument against making this method public. With this method protected, it is necessary to first encode as a BitMatrix, extract the first row, and the convert the resulting BitArray to a bool array. This all can be avoided if the method is made public.

suggested by Martin Burke of zint (See https://sourceforge.net/p/zint/code/ci/68566fefd2a4623041b0232a5941f8fed1e22018/) (#1459) Quote of Martin's proposed changes to the spec: The algorithm can be salvaged to be at least sound by making those changes, e.g. by adding to step e): "1) If the next character cannot be encoded as X12, switch to ASCII mode and go to step b)." (and renumbering the following sub-steps). Similarly step f): "1) If the next character cannot be encoded as EDIFACT, switch to ASCII mode and go to step b)."
