2022-01-12Minimal encoding for Data Matrix with multi ECI and GS1-FNC1 support (2nd) ↵AlexGeller11-3/+148
(#1479) * Added Data Matrix minimal encoding with multi-ECI and GS1-FNC1 support. * Added support for MACRO-5 and MACRO-6 * Improved comment
2021-11-16Fix of error in specification ISO/IEC 16022 Second edition Annex P as ↵AlexGeller11-0/+27
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)."

2021-10-17Add support for EncodeTypeHint.CHARACTER_SET for compacted QR-Codes (#1450)AlexGeller11-52/+56
* Added experimental version of QR-Code compaction which can be activated via EncodeHintType.QR_COMPACT * - Changed algorithm from recursive divide and conquer to iterative Dijkstra - Performed the requested modifications. * Added better debug output and better documententation of the algorithm * - Added missing error handling in case of a failing assert - Fixed typo in the documentation * Fixed bug that the minimal encoder would fail with an internal error if the string to encode contained only characters from ISO-8859-1 and on or more character that is not defined in any of the ISO-8859 characters sets. * Added unit tests * - indented class and method comments - fixed code indententation - added vertical spacing in statement lists to separate locical blocks - added comments to document some numeric constants - commented out debug logging - made class ResultNode final and all but the methods called by the class Encoder private. * - Fixed indentation and line length - Improved comments * Fixed line length * Improved comments * - Whitespace and comment style changes - Replaced string concatentation with StringBuilder.append() - Replaced Vector with ArrayList - Made members that are ony modified in the constructor final - Made other minor changes * - Made more members final - replaced assert by throwing an IllegalStateException * Changed internal data representation to be based on java.util.LinkedList * Removed uneccessary spaces and comments * Improved the debug output (now produces a compacted graph) * - Added code to exclude not supported ECIs - Fixed regression that bits were incorrectly computed * - Fixed regression that bits were wrongly computed - Improved compaction - added a commented proposal for unit test that makes use of the decoder to validate the encoded bits * Removed useless comparisons * Removed commented code * Optimization: added code to cache the value of LinkedList.size(). * Added more test cases * - Added support for EncodeTypeHint.CHARACTER_SET - Added support to encode in all ISO-8859 character sets available on the platform - Removed code that handles failing asserts * - Replaced string switch case with HashMap lookup - Reintroduced asserts * - Replaced <code> with {@code} - Changed indentation in comment - Simplified code * Improved documentation * Added comment about decoding compatibility with zxing. * - Made MinimalEncoder responsible of ensuring that the bits fit in the returned version. - Removed asserts that throw NPE in case of falure. * Restricted encoder to use only encodings defined in CharacterSetECI * Improved clarity and readability of the algorithm and of the datastrutures used. - Minimizing algorithm is based on immutable edges - ResultList now contains exaclty one ResultNode per mode and possibly several as before * Changed unit tests (forgotten in previous push)
2021-10-12Fix qr compaction (#1449)AlexGeller11-82/+116
* - Added missing error handling in case of a failing assert - Fixed typo in the documentation * Fixed bug that the minimal encoder would fail with an internal error if the string to encode contained only characters from ISO-8859-1 and on or more character that is not defined in any of the ISO-8859 characters sets.

2020-11-08Aztec encode with ECI for non-default character sets (#1330)Dan Lenski4-46/+58
* Aztec encoder: add ECI codes according to character set Added redundant methods to avoid modifying existing tests. * fix testAztecWriter - ISO-8859-1 cannot actually encode Euro symbol ('€'); this test case only passed before because the Decoder wasn't actually doing the bytes→String decode, but simply round-tripping an unknown byte. - Add extra test cases for implicit ISO-8859-1 (without ECI code), explicit ISO-8559-1 (with ECI code), and Shift_JIS * remove unnecessary conversion between String and byte[] in Aztec EncoderTest and DetectorTest * Aztec DecoderTest: use constants for charsets * Aztec Code: remove unnecessary conversion between Charset and Charset.name() strings * PDF417, QR, DataMatrix: remove unnecessary conversion between Charset and Charset.name() strings Includes replacing StringUtils.guessEncoding() with .guessCharset(), to return Charset rather than String. This change makes the tacit assumption that Shift_JIS charset *will* be available. There are existing comments suggesting that it might not always be available… but the existing *tests* assume it will be.
2020-10-28Aztec Code: decode ECI and FNC1 (#1328)Dan Lenski3-14/+71
* decode Aztec FLG(n) Per https://en.wikipedia.org/wiki/Aztec_Code#Character_set, FLG(0) → FNC1, FLG(1-6) → ECI identifier Decode FNC1 as 0x1d (ASCII escape character; same as Code128, DataMatrix, others) Not doing anything with ECI yet, but this at least fixes the mis-synchronization of the bit stream that comes from ignoring the bits that follow it. * include ecLevel (percentage) in DecoderResult for Aztec * Aztec decoder: follow character set indicated by ECI codes Modeled on PDF417's DecodedBitStreamParser * add testAztecResultECI and testHighLevelDecode to aztec.decoder.DecoderTest The latter includes non-ECI, ECI, and mixed test cases.
