1bae498386 properly fix compile issue by forward declaring QZXing in QZXingFilter. Had to make decoder variable as pointer in order to avoid the compiler requirement to known the exact size of the class...that had to be forward declared. Properly addresses issue #16 2017-01-17 13:37:20 +02:00

a3e71ec1e7 created qzxing_qml and qzxing_multimedia qmake CONFIG tags for QZXing.pri to allow the control of dependencies based on the needs. qzxing_qml enables QML specific parts of the library. qzxing_multimedia enables QZXingFilter which requires Qt's multimedia. 2017-01-15 20:36:41 +02:00

594b178501 Make QZXingFilter "official" by moving it out of the example folder 
The filter is much more performant than using the QZXing API in an
imparative way for the use-case of live-analyzing video frames in QML.

61508f461a Optimize: Return the matrix reference directly instead of copying it. 
This removes another copy of frame data, thereby improving the FPS
of the QZXingFilter example noticeably.

bb903ca27e Enable all decoders by default 
Otherwise this leads to access of uninitialized, when one forgets

bd96c910e9 Merge pull request #6 from sergey-platonov/isnan-fix 
zxing::isnan for non-msvc compilers was implemented with c99 function,
which is still not fully supported by some compilers (e.g., GCC).
Added an implementation for compilers without c++11 or c99 support. And wrapped
all related code in #if.

d49b7e12ad zxing::isnan implemented for different cases 
zxing::isnan for non msvc compilers was implemented with c99 function,
which is still not fully supported by some compilers (e.g., gcc).

I've added imlementation for compilers without c++11 or c99 support. And wraped
all releated code in #if.

d5e5c895d8 For backward compatibility, after merging pull request #3, the original tagFoundAdvanced signal has been reimplemented. Also added try catch clause around the new singal since in a lot of cases it fails to detect the decoded barcode's rectangle. To be improved. 2016-09-27 02:06:54 +03:00
