zbar

I've got a website hosted at Heroku , and I now want to use the python-qrtools package which uses the ZBar bar code scanner . On a regular debian (based) I can do a simple: sudo apt-get install python-qrtools According to the command dpkg-query -L python-qrtools , this installs the following: /usr/lib/python2.7/dist-packages/qrtools-1.2.egg-info /usr/lib/python2.7/dist-packages/qrtools.py /usr/share/doc/python-qrtools/copyright /usr/share/doc/python-qrtools/changelog.Debian.gz When I look at the imports of qrtools.py , it also does an import zbar , which is (as far as I understand) the python

I need to have a QR scanner in my project. I use ZBar for doing this task. Mainly I did a very small change on the example code given by ZBar git example to do the job. I need to show the scanned result in a browser(if url) or in a dialog(if normal information). Every thing working well with my code given bellow except if I try to show the url after scan a qr code in browser. When I come back to my app from the browser the camera viewport turns black and remain inactive. I tried to get back the camera active to scan another qr code but i failed. I tried to reopen the camera in my onResume()

On samsung galaxy s6 edge my app crashes when calling the zbar sdk, for scanning. I think it is because I don't have an arm64 version of zbar. This is the end of the crash log: java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/.../base.apk"],nativeLibraryDirectories=[/data/app/.../lib/arm64, /vendor/lib64, /system/lib64]]] couldn't find "libiconv.so" at java.lang.Runtime.loadLibrary(Runtime.java:366) I seen in my project that i don't have arm64 jni libs for zbar is this related ? and if so where can i get libiconv.so libzbarjni.so for arm64 ? So

When scanning QR codes with ZBar the string resulting from the process does not display unicode characters properly. The word Márti encoded as a QR code by any free to use QR code generator (like http://qrcode.kaywa.com ) would result in Mﾃ｡rti . In other SO questions ( 1 , 2 ) it was suggested to embed a BOM at the start of the resulting string, but doing this: NSString *qrString = [NSString stringWithFormat:@"\xEF\xBB\xBF%@",symbol.data]; or this: NSString *qrString = [[NSString alloc] initWithFormat:@"\357\273\277%@", symbol.data]; resulted in the same, flawed result with the Asian

I am using Zbar for reading QRCode. I use this https://github.com/DushyanthMaguluru/ZBarScanner example for my activity. The Question is how can I show cameraView on my FrameLayout ? EDIT: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); mCamera = getCameraInstance(); if(!isCameraAvailable()) { cancelRequest(); return; } requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); mAutoFocusHandler

I'm trying to use the Zbar library's QR code detection methods on images I extract with OpenCV's camera methods. Normally the QR code detection methods work with images (jpg, png, etc.) on my computer, but I guess the captured frames of OpenCV are different. Is there a way of making the captured frame into a PIL Image? Thank you. from PIL import Image import zbar import cv2.cv as cv capture = cv.CaptureFromCAM(1) imgSize = cv.GetSize(cv.QueryFrame(capture)) img = cv.QueryFrame(capture) #SOMETHING GOES HERE TO TURN FRAME INTO IMAGE img = img.convert('L') width, height = img.size scanner = zbar

Trying pip-3.2 install zbar Gives the error message shown in the picture sudo pip-3.2 install zbar gives a similar error Any ideas? (I do have it installed with Python 2.7) UPDATE: Both libzbar-dev and python3-dev are up to date. Still... No module named 'zbar' 回答1: assuming you're using a debian derivative (like ubuntu), you need to install zbar 's developement package, which contains the header file
