2D barcode scan about quaggajs HOT 10 CLOSED

@serratus , Does it support 2D barcodes now??

from quaggajs.

Sorry, 2D barcode decoding is not yet implemented. Currently Code128 and EAN are the only options available. In the near future, a few more one-d barcodes will be supported.

2D barcodes are further down the roadmap and will require quite some effort. Maybe someone in the community can help out.

thank you for your quick response. can you please point me to something when i can decode 2d barcodes or can you please help me in getting the barcode image from the video stream so that i can pass the image to a barcode reader. your help is so much appreciated thank you

Sorry, I don't quite understand what your requirements are. Do you need it to run in a web-browser? You could try zxing for running it natively on your phone. But I don't know any implementation running in the browser.

i am trying to run in a web browser. i am able to open camera take a snapshot from video and send the image to the server and passing that bitmap image to zxing barcoder reader But the problem is with the snapshot the images are not clear and zxing reader cannot recognize the bitmap. can you suggest a way to fetch the barcode image out of the viedo stream?

from quaggajs.

One way to get clearer images is by using the html5 File-API and prompt the user to take a picture with his/her camera.

If you want to use getUserMedia, try to increase the resolution of the camera by setting the appropriate constraints. Take a look at camera_access if you want to know how.

i tried setting the below code for video but it stays the same can you please help
video: {
"mandatory": {
"minWidth": "1280",
"maxWidth": "1280",
"minHeight": "720",
"maxHeight": "720",
"minFrameRate": "30"
},
"optional": []
}

I've created a gist which demonstrates how to request the camera stream, including constraints (for Chrome only). Additionally, the video stream is copied to a canvas element which can then be used to capture the frames. You can take a look at the canvas API here where you can find the calls for your use-case (most probably toDataURL())
