TAB key in Code128 barcodes

由 ♀尐吖头ヾ 提交于 2019-11-27 08:00:05
问题 I'm trying to create a barcode with a TAB key within it. It seems as though some generators (only found one thus far) uses ~ as a TAB key. But I can't seem to get it to work with any of the other generators. I've also read that Code128 A supports ASCII, meaning "HT" should work as a Horizontal Tab. Any ideas on what Code128 decrypts as TAB? 回答1: Generating a Code 128 containing an ASCII control character Code 128 can be used to encode any character in the Latin-1 character set, including

I want to take a numerical string and generate a simple barcode that can be read by any scanner. I can already use the camera and read a barcode but now I would like to generate a barcode. Does anyone know of an sdk that will allow me to do this, resources or code snipets? Thank you The only free library to do this is Cocoa-Touch-Barcodes , which is a fork of cocoabarcodes . If you are considering commercial libraries, there is one called iPhone Barcode Generator . update Check this objective-c port of ZXing : https://github.com/TheLevelUp/ZXingObjC Include : #import "NKDBarcodeFramework.h" in

Do the Amazon web service APIs support barcode/UPC queries?

由 折月煮酒 提交于 2019-11-27 05:29:05
问题 I skimmed through their documentation and found it a bit overwhelming at first. I know you can search for items by entering a UPC (the number below a 1D barcode), but I couldn't find a word about it in the API. What I want to do is perform a product lookup by doing a UPC search after scanning a barcode. 回答1: Here is a page from the e-commerce service docs which shows how you can use the ItemLookup method to find a specific product by UPC. Note that default IdType for the ItemLookup is ASIN,

Extracting information from a scanned GS1-type barcode

由 我只是一个虾纸丫 提交于 2019-11-27 05:13:36
I am developing an app on Android Studio to get the expiry date of items upon scanning the barcode. I don't want the user to install ZXing barcode app separately so I embedded the ZXing code into my project. Doing this I have been able to obtain the product identifier. I also want to get product information such as the description, manufacturer and expiry date using the scanned barcode data. How can I do that? There are two processes involved in obtaining the information represented by a GS1-type barcode that stores data in GS1 Application Identifier Standard Format. Extraction of the data

What is the actual HEX / binary value of the GS1 FNC1 character?

由 我是研究僧i 提交于 2019-11-27 05:06:38
I have searched many a page on wikipedia, the official GS1 specifications, but have yet to find a definite answer to the question What is the actual HEX / binary value of the GS1 FNC1 character? There is much information about how to use the GS1 identifiers, how to print the barcodes with ZPL and how to encode the FNC1, but I want to know the actual HEX value of that character. The special function characters such as FNC1 through FNC4 do not have any direct ASCII representation. Each symbology that supports such characters has a different scheme for encoding them in its internal representation

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();

问题 I'm looking to integrate some sort of barcode scanner into a phonegap application. I just need to find out whether it is possible on all of the major platforms (iOS/Android/Blackberry/WP7)?
