----------------
|
|
Zint is a suite of programs to allow easy encoding of data in any of the
|
|
wide range of public domain barcode standards and to allow integration of
|
|
this capability into your own programs.
|
|
|
|
Zint is able to encode data in the following formats:
|
|
|
|
Code 11, Standard Code 2 of 5, IATA Code 2 of 5, Industrial Code 2 of 5,
|

|
|
|
Version 2.5.0:
|
|
Support for DotCode and Han Xin code. ECI code processing. Output to BMP, GIF
|
|

|
|
Many minor fixes and improvements.
|
|
|
|
Version 2.5.1:
|
|
Numerous bugfixes, especially with Data Matrix thanks to extensive testing
|
|
by brunt@SF
|
|
|
|
Version 2.6.0:
|
|
Update front end to Qt5. Output to EMF and TIF. Copy to clipboard. Update
|
|
to latest draft of DMRE. Usual bugfixes.
|
|
|
|
Version 2.6.1:
|
|
Library bugfixes: EDIFACT unlatch in Data Matrix, Add UPNQR, Improved Aztec
|
|
data compression, Detect Code 128 data too long, Make error codes consistent.
|
|
GUI improvements: Additional clipboard options, remove border width bug,
|
|
remove changing background colour bug, remember more settings and make GUI
|
|
more consistent with user expectations. All windows now resizable and more
|
|
information given when batch processing.
|
|
|
|
Version 2.6.2:
|
|
Further bugfixes in Aztec and DotCode. Expand escape sequence support

|
|
|
Version 2.6.4:
|
|
Fixed bugs: EMF output, maxicode plot/content
|
|
Datamatrix DMRE updated to the ISO/IEC29158 version. This is incompatible in the way,
|
|
that the old -vers numbers for DMRE are re-assigned.
|
|
The separator of GS1-datamatrix may be switched from FNC1 to GS.
|
|
GS1 field length check AI 8009 and 7230 to 7239 currected.
|
|
|
|
Version 2.6.5:
|
|
Fixed bugs:
|
|
backend/main.c was missing
|
|
Maxicode bullseye rastering for scale = 0.5
|
|
Crash in uto to eci.
|
|
eci ISO 8859-16 table missing data line
|
|
upce check for 7 digit input (causes crash) and BARCODE_UPCE_CHK -> BARCODE_UPCE mapping removed
|
|
US imail check for invalid barcode identifier and allow 0/5/9/11 length zip
|
|
maxicode code set correction
|
|
cmake flags for debugging and sanitize options
|
|
unit tests for the changes, with a simple test suite based on qrencode/tests
|
|
|
|

|
|
Fixed bugs:
|
|
Ticket 161: PDF row size may be set
|
|
Ticket 155: PDF numeric compaction

|
|
Ticket 119: Crash on bullseye raster drawing
|
|
qtzint: Micro-QR version option choice corrected (+1 missing).
|
|
Datamatrix: code corruption when ECI was encoded and base256 encoding was automatically chosen.
|
|
|
|
Version 2.6.7 2019-10-07:
|
|
|
|
Changes:
|
|
Ticket 127: Allow to code ECI 3 if explicitly given for debug purposes.
|
|
***Incompatible change**
|
|
"--eci 3" now leads to included ECI information.
|
|
"--eci 0" may now be used to not include any ECI information.
|
|
The default of the parameter changed from 3 to 0.
|
|
|
|
Fixed bugs:
|
|
Ticket 146, 165: fix wrong encoding of RSS composite codes

Version 2.7.1 2020-02-01:
|
|
Changes:

|
|
- PDF417: remove obsolete codeword number option in qzint.
|
|
Option removed in qtzint.
|
|
- Removed annex B (3 digit country codes) and annex C (GS1 General Specification)
|
|
from the manual. This material may be found elsewhere.
|
|
- MAC homebrew remark added to the documentation
|
|
- Correct cmake file to match BSD-3-clause licence
|
|
Bugs:
|
|
- Correct uninitialized warning in gridmatrix.call
|
|

|
|
|
|
Version 2.8.0 2020-04-10:
|
|
Changes:
|
|
(New) Tests for auspost, codablock, composite, dotcode, general, telepen, upcean,
|
|
all output formats,
|
|
- QR, Han Xin, Grid Matrix: the multi byte compaction schemes (ex: Kanji)
|
|
are used by some decoders as codepage information (Ex: GB2312) and output
|
|
may be translated to UTF-8. This may destroy the data in a not controlable
|
|
manner.
|
|
In consequence, multibyte compaction schemes are disabled by default.
|
|
The new option --fullmultibyte (option_3 = ZINT_FULL_MULTIBYTE) enables this
|
|
optimisation.
|
|
- Add new symbology "Ultra Code" with the ability to output colour codes.
|
|
Bugs:
|
|
- Ticket 181 penetration test found many bugs:
|
|
- Auspost: null bytes in content caused segfault
|
|
- Codablock: data 0x1a..0x1f caused segfault
|
|
- Dotcode: overrun in binary mode, overrun in codeword_array buffer
|
|
Correct encoding of HT/FS/GS/RS when shifting to code set B
|
|
- empty or unreadable input file
|
|
- telepen: buffer overflow
|
|
- EANUCC: buffer overflow on multiple + (multiple extension bars)
|
|
- Maxicode: index overrun on numeric compaction
|
|
- CodeOne: Simple i indexing not sp + i in C1_ASCII numeric latch loop.
|
|
- Aztec: free memory
|
|
- Ticket 183: Databar stacked separator correction
|
|
- Ticket 182: Output bitmap type was char, where some targets assigned 0
|
|
if pixel colour >127 (e.g. negative). API change to use unsigned char.
|
|
- HanXin: wrong codepage, gb2312 instead gb18030.
|
|
- PDF417: corrected alloced sizes to max characters
|
|
- Ticket 189: FNC1 encodation fixed (FLG(0) missing after FLG(n))
|
|
- PCX format: added missing bytes_per_line if bitmap width is odd.
|
|

BEFORE POSTING TO THE LIST
|
|
--------------------------
|
|
Please note the following points...
|
|
* Zint is primarily developed for Linux. While we have some experience of
|
|
using Zint on Windows we may be unable to resolve problems if they are
|
|
specific to other operating systems. We cannot provide support for using
|
|
Zint with commercial packages such as MS Office or Crystal Reports.
|
|
* Always ensure you are using the latest version of Zint before posting bug
|
|
reports - the bug you are reporting may have been fixed already.
|
|
* Please remember to state what operating system you are using and include
|
|
enough information to allow us to reproduce the error - including input
|
|
data if appropriate.
|
|
* Please DO NOT post messages asking for us to change the license
|
|
arrangements. You will be ignored.
|
|
* Please remember that Zint is developed by volunteers. While we attempt to
|
|
answer all messages within a week, this is highly dependant on external
|
|
circumstances.
