zbar

问题 I’m building an app for paying parking tickets. The problem is that we have a specific type of barcode that AVFoundation can’t read. I tried to found other frameworks to replace the AVFoundation, but turns out all of them use AVFoundation underneath. The only framework I found capable of reading it is the ZBar, but we’re not planning to use it since it hasn’t been updated for 6 years. Do you guys have any idea why it isn’t working?

问题 I am trying to update the recipe for zbar from 0.10.0 to 0.20.1. Here is the original recipe: https://github.com/openembedded/meta-openembedded/blob/master/meta-oe/recipes-support/zbar/zbar_0.10.bb My modified recipe is at the bottom of this question. The package does compile, but the problem is that something happens during the "packaging" step and the "work" directory is wiped out except for the "temp" directory inside the "work" directory. During compilation, if I list the files in the

问题 I want to use zbar with python on Linux Mint. I tried apt-get zbar and I didn't find any packages. So I tried to use apt-get install zbar-tools and that seemed to work. I tried to run basic example code that starts with: #!/usr/bin/python from sys import argv import zbar import Image However, that code crashes with the error: Traceback (most recent call last): File "./p4.py", line 3, in <module> import zbar ImportError: No module named zbar Normally I would expect to find some file named zbar

问题 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

问题 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)

问题 I had one problem during building application in the recent Xcode 5.1. Compilation fails with "Undefined symbols for architecture x86_64" error. I build my project with Valid Architecture: armv7, armv7s and arm64. After switch to the newest environment (Xcode) I rebuild libzbar.a library in the same architecture ( I have done it based on solution found at: Linker Error in Xcode-5) Maybe somebody also had same problem and finally he had solved it, please share with solution:) 回答1: I had the
