How to scan driver's license (PDF417) using xamarin forms + zxing on iOS 10.2

由 点点圈 提交于 2019-11-30 18:38:14
问题 I am using Xamarin forms to write an iOS app and using the ZXing library to scan barcodes. I am trying to read a driver's license (PDF417) barcode, but the library is not able to recognize that barcode. If I include UPC or other barcodes in the PossibleFormats, they are scanned correctly. I am also certain the barcode I am trying to read is PDF417 barcode because Scandit is able to recognize it correctly while using only PDF417 barcode. Here is the code I am using. What do I need to change so

So I planned something and need several information from you all There are lots available on appStore. One of them is pic2shop(Which is a free application).

Vision Framework Barcode detection for iOS 11

由 假如想象 提交于 2019-11-30 15:14:02
问题 I've been implementing a test of the new Vision framework which Apple introduced in WWDC2017. I am specifically looking at the barcode detection - I've been able to get after scanning the image from Camera/Gallery that it's a barcode image or not. However, I can't see what the actual barcode value or the payload data when looking at the barcodeDescriptor. There appears to be nothing exposed on the https://developer.apple.com/documentation/coreimage/cibarcodedescriptor page to identify any of

How can I extract an AVMetadataObject from a UIImage?

由 随声附和 提交于 2019-11-30 12:13:22
问题 I'd like to use iOS 7's new barcode scanning functionality with a UIImage instead of live capture from one of the device's camera. I already have the detection working fine with an AVCaptureDeviceInput . The best way I think to do this would be to create a concrete subclass of AVCaptureInput that provides media data to an AVCaptureSession from a UIImage . However, I can't find any documentation or examples on how to subclass AVCaptureInput , so I'm at a loss. An alternative would be to

Enhanced iOS barcode scanner library?

由 江枫思渺然 提交于 2019-11-30 11:24:43
问题 We're creating an iOS app that basically scans badges at events and collects contact info. We're looking for an iOS library that can read not only the number of the barcode, but also any additional information that's included (contact info). Does anyone have any library suggestions or will this have to be a custom library? Thanks in advance! 回答1: Updated: Use AVCaptureMetaDataOutput in AVFoundation which works with minimum deployment target iOS 7. Previous Answer: Have been using ZBar SDK in

How to get ZPL code from a ZebraDesigner label?

由 余生颓废 提交于 2019-11-30 10:36:17
问题 I'm using ZebraDesigner 2.2.2 (Build 2728). Is there a way to extract the ZPL code from ZebraDesigner? I can't even export it to ZPL file, the only option I have is saving it as .lbl . 回答1: You can add a new ZebraDesigner ZPL driver to the system and use a file as the port. Then when you "Print" the document, it will write the ZPL code to the file. Note that it might have some header information before the first ^XA which you might not need. UPDATE : (How to add local port on a driver) Go to
