问题 Data Matrix barcode support was added to iOS 8 and I'm able to use it to read Data Matrix barcodes if they are black on white (dark on light).

Anyone have an idea how to get iOS 8 to read a light on dark Data Matrix barcode? 回答1: You can invert the colors of your AVCaptureSession in real time, allowing you to read the Data Matrix

Barcode scanner and input fields, replace new line call to tab call?

由 只愿长相守 提交于 2020-01-06 13:45:06
问题 So barcode scanners end each scan with a carriage return, which messes up forms by submitting them. Is it possible to change this so that it calls a tab instead (thus moving to the next input field)? I did a find a solution here that does that, but it manually focused on each input using their id's. The number of inputs I have is variable so I cannot do that. 回答1: Yes, it is possible. There are 2 ways: reprogram the barcode reader to send the TAB key instead of a carriage return after reading

How to render several barcodes with Zend 2?

由 我的梦境 提交于 2020-01-05 07:49:22
问题 I'm trying print several barcodes using the Zend\Barcode namespace. The problem is reading the manual I can't print more than one barcode. I can't print a echo before the barcode too. How can I print several barcodes and texts together? The code I'm using is similar to this one: use Zend\Barcode\Barcode; $barcodeOptions = array('text' => '123456'); $rendererOptions = array(); Barcode::render( 'code39', 'image', $barcodeOptions, $rendererOptions ); $barcodeOptions = array('text' => '654321');

Unable to scan Code 128 with Zxing Android

问题 I have integrated the ZXing barcode reader in my android application. It scans most of the codes, but I have a electricity bill which it is unable to scan (using a Galaxy Ace 5.0MP). I think the problem is due to camera resolution and focus, because when I tried the same barcode on using Xperia SL (12.1MP) I got the result. So is there any solution to this problem? I have attached a sample image of the barcode. . 回答1: This scans instantly by the library itself: http://zxing.org/w/decode?u
