How To Use ZXing C# Port

由 不想你离开。 提交于 2019-11-27 02:57:11
问题 NOTE: My original question was about whether the ZXing C# port is reliable, but here, I'm trying to figure out how to use it. Thus, they are not duplicates. I'm trying to use the ZXing C# module, but I'm having trouble. Does anyone who has used ZXing before know how to do it correctly? Unfortunately, the C# documentation is quite small. My current code is: using com.google.zxing; using com.google.zxing.client.j2se; using com.google.zxing.common; //... Reader reader = new MultiFormatReader();

how does “com.google.zxing.client.android.SCAN” work in android?

由 南笙酒味 提交于 2019-11-26 22:07:05
问题 I developed a BarcodeScanner app with ZXING library. for that I downloaded the complete library and added it to my proj and called an Intent with URI:"com.myproject.vinscan.client.android.SCAN". but later I found that, instead of downloading and including all packages of ZXING into our proj, we can just use the URI for Inetnt as "com.google.zxing.client.android.SCAN". My doubt is, how is it working without the libraries. It is working even in offline mode(without WIFI/GPRS). are the libraries

QR Code encoding and decoding using zxing

由 末鹿安然 提交于 2019-11-26 19:29:35
Okay, so I'm going to take the off chance that someone here has used zxing before. I'm developing a Java application, and one of the things it needs to do is encode a byte array of data into a QR Code and then decode it at a later time. Here's an example of what my encoder looks like: byte[] b = {0x48, 0x45, 0x4C, 0x4C, 0x4F}; //convert the byte array into a UTF-8 string String data; try { data = new String(b, "UTF8"); } catch (UnsupportedEncodingException e) { //the program shouldn't be able to get here return; } //get a byte matrix for the data ByteMatrix matrix; com.google.zxing.Writer

How to decode a QR-code image in (preferably pure) Python?

由 ╄→гoц情女王★ 提交于 2019-11-26 18:45:17
问题 TL;DR : I need a way to decode a QR-code from an image file using (preferable pure) Python. I've got a jpg file with a QR-code which I want to decode using Python. I've found a couple libraries which claim to do this: PyQRCode (website here) which supposedly can decode qr codes from images by simply providing a path like this: import sys, qrcode d = qrcode.Decoder() if d.decode('out.png'): print 'result: ' + d.result else: print 'error: ' + d.error So I simply installed it using sudo pip
