History

flyashi d2499c38bb C++: ITFReader.cpp was throwing wrong exception ITFReader.cpp:75 was catching and re-throwing Exception instead of ReaderException, causing scanning to terminate prematurely in some cases (i.e. core/test/data/blackbox/ean13-1/23.JPG). The calling function, MultiFormatOneDReader::doDecode, is only catching ReaderException's. An Exception would be passed all the way up to the caller, even if scanning hasn't finished yet for other decoders for other rows. git-svn-id: https://zxing.googlecode.com/svn/trunk@1493 59b500cc-1b3d-0410-9834-0bbf25fbcc57		2010-07-27 23:02:28 +00:00

README

This is only tested on Linux. With some trouble, it might work on Windows as well.

To build the library only:
- Install scons
- Run "scons lib" in this folder (cpp).

To build the unit tests:
- Install cppunit (libcppunit-dev on Ubuntu)
- Run "scons tests"
- Run "testrunner" in the build folder

To build the test utility:
- Install Magick++ (libmagick++-dev on Ubuntu)
- Run "scons zxing"

An simple example application is now also included, but no compilation instructions yet.

To clean:
- Run "scons -c all"

To use the test utility:
- Basic usage:
  - "mkdir testout"
  - "zxing testout *.jpg > report.html"
- With the zxing test data, from the cpp folder:
  - "mkdir testout"
  - "build/zxing testout ../core/test/data/blackbox/qrcode-*/* > report.html"

To format the code:
 - Install astyle
 - Run ./format

To profile the code (very useful to optimize the code):
 - Install valgrind
 - "valgrind --tool=callgrind build/zxing - path/to/test/data/*.jpg > report.html"
 - kcachegrind is a very nice tool to analize the output
