I am using react-native-camera to scan barcodes. On iOS, where I started developing, everything works well as expected. On Android though, it will just not fire onBarcodeRead
when a barcode is focused with the camera.
The relevant piece of code is the following:
...ANSWER
Answered 2021-May-10 at 17:51Actually I did not get it running. In the end, I decided to use onBarCodeRead
on iOS and onGoogleVisionBarcodesDetected
on Android. That was the only way I got it running on both platforms.
QUESTION
I am developing a barcode reader with Xamarin.Forms. And I'm trying to scan the image on Android device.
First I select the image from the gallery with Xamarin.Essentials MediaPicker and from the path of this image I get an RGBLuminance with the Dependency class.
Then I am trying to decode this RGBLuminance with the Decode() method of the ZXing BarcodeReaderGeneric class. However, the result always returns null.
It is my demo project : https://onedrive.live.com/?authkey=%21AFLjjM91wgZkBGU&cid=58BE2C2C3447FFA2&id=58BE2C2C3447FFA2%219829&parId=root&action=locate
Command in the ViewModel class:
...ANSWER
Answered 2021-Apr-14 at 19:18You should change the line
return new RGBLuminanceSource(rgbBytes, bitmap.Height, bitmap.Width, RGBLuminanceSource.BitmapFormat.RGB32);
to
return new RGBLuminanceSource(rgbBytes, bitmap.Width, bitmap.Height, RGBLuminanceSource.BitmapFormat.RGB32);
And to be more accurate with the RGB format you should
- change RGBLuminanceSource.BitmapFormat.RGB32 to RGBLuminanceSource.BitmapFormat.ARGB32
- or change rgbBytesList.AddRange(new[] { c.A, c.R, c.G, c.B }); to rgbBytesList.AddRange(new[] { c.R, c.G, c.B, c.A });

I'm trying to use react-native-camera and I want to send tokens from the first page to the camera page. how can I get a token on the camera page? I am not sure how to solve this problem, I tried to change the camera page to function based component but I get more errors :) so I'd be very happy if you guys help me out
the first page is function-based component

Answered 2021-Jan-19 at 11:49You cannot. if you look at the source code you will see that what it does is call a java app with the provided path (Specifically com.google.zxing.client.j2se.CommandLineRunner

If you need to pre-process your image then you will have to save it somewhere and pass the path to it to your library

I have strange issue with GIT, my VS2019 solution placed in folder ZebraScanner. Also I have two VS2019 project file in ZebraScanner\Barcoder\Barcoder (source code) and ZebraScanner\BarcoderSetup (Installer project). When I save source code changing in project ZebraScanner\Barcoder\Barcoder, GIT making autocommit automatically. As a result I can not track code changing.
Also when I select git menu in solution explorer I receive something strange message about Azure. I don't working with Azure at all.
How is possible to fix this issue?

QUESTION
I am using vision framework to detect barcodes. I want to show a rect around the barcode with highest confidence on live video, meaning, I want to track that rect to the barcode seen on the live preview.
So I have this code to detect the barcodes within a roi.
...ANSWER
Answered 2021-Feb-03 at 17:34I did something similar a while ago and wrote an article on it. It's for VNRecognizeTextRequest
not VNDetectBarcodesRequest
, but it's similar. This is what I did:
- Perform
VNImageRequestHandler
continuously (once it finishes, start another again) - Store the detection indicator view in a property
var previousTrackingView: UIView?
- Animate the detection indicator to the new rectangle whenever the request handler finishes
- Use Core Motion to detect device movement, and adjust the frame of the detection indicator
Here is the result:
As you can see the height/y coordinate is not very accurate. My guess is that Vision only needs a horizontal line to scan barcodes - like those laser scanners in grocery stores - so it doesn't return the full height. But that is a different problem.
PerformVNImageRequestHandler
continuously (once it finishes, start another again)
For this, I'm making a property busyPerformingVisionRequest
, and whenever this is false, I call the Vision request. This is inside the didOutput
function which gets called whenever the camera frame changes.
QUESTION
I am trying to decode barcodes that appear on a region of interest, that is 80% of the screen width and 20% of the screen height and centered on both directions (blue rectangle).
The camera pixel buffer is rotated right.
This is what Apple has to say about this orientation:
The (x,y) pixel coordinates of the origin point (0,0) represent the top row and rightmost column, respectively. Pixel (x,y) positions increase top-to-bottom, right-to-left. If an image is encoded with this orientation, then displayed by software unaware of orientation metadata, the image appears to be rotated 90° counter-clockwise. (That is, to present the image in its intended orientation, you must rotate it 90° clockwise.)
So, when I define the region of interest of my VNDetectBarcodesRequest
I do like this:
ANSWER
Answered 2021-Feb-01 at 19:17Just making sure, if you look at regionOfInterest
, the documentation says:
The rectangle is normalized to the dimensions of the processed image. Its origin is specified relative to the image's lower-left corner.
So the origin (0,0) is at the bottom left. With your current CGRect,
