also add min version to all CMakeLists.txt
GUI: add missing accelerator to UPCA/UPCEAN.ui "Guard Whitespace";
add default value to some "Default" buttons;
reformat DAFT examples again; add \^@ to special escs hint
outputting to in-memory buffer `symbol->memfile` instead of to
file `symbol->outfile`, ticket #301
Add "README.clang-tidy" and ".clang-tidy" options file
Suppress some warnings
project builds (will add back in future if go fully CMake)
- NO_PNG -> ZINT_NO_PNG and new API function `Zint_NoPng()` to
determine if no PNG support in libzint; replace use in GUI with
backend_qt method `noPng()`
Either shared or static (or both) libraries can be built now.
Executables (zint and zint-qt) are linked with the static library if the shared
library it not built.
bmp/emf/ps.c: allow for foreground colour in ULTRA
bmp/gif/pcx.c: allow for BARCODE_STDOUT (fflush/fclose)
emf.c: hexagon rotation field not used; dont't use float index in font loop; Windows stdout binary mode
png.c: remove unused 8-bit; simplify libpng error handling and fclose outfile on error
ps.c: fix buffer overflow on colour_to_pscolor() CMYK
tif.c: fix BLACKISZERO indexes
CODE39: simplify check digit setting
reedsol.c: rs_uint_init_gf() log/alog tables must be zeroed
ZBarcode_Encode: debug: fix access out-of-bounds on non-NUL-terminated source if length < 10
manual.txt/zint.h: document NUL-terminated strings
tests: cover further cases for output (bmp/emf/etc), eci/gb18030/gb2312/sjis, reedsol, AZTEC, CODE39
PLESSEY: add options NCR weighted mod-10, hide check digit(s) in HRT
test suite: now runnable under MSVC 2019, 2017, 2015, MinGW/MSYS
win32/README: update with MSVC 2019 and CMake instructions
Expose the ability to turn these dependencies off, which results in reduced
functionality. However, it enables a developer using the zint library to
instruct cmake to build a libzint as deployed by e.g. build servers which
don't have png/zint installed, without having to uninstall those libraries
from the development system
Linking against the dynamic zint library requires LD_LIBRARY_PATH and friends
to be set, which complicates the test setup. On the long run, we want to be
able to test both the dynamic and the static (at the same time), though
