QUESTION
I am using Zxing Scanner component in Angular version 12. I faced this error in many places..
...ANSWER
Answered 2021-Jun-11 at 13:17The reason why the error occurred is because format is a string and can be anything so when you use it in BarcodeFormat, typescript doesn't know whether format is one of the keys of BarcodeFormat.
Therefore, we need to tell typescript format is actually part of the keys in BarcodeFormat.
To do it, we can use the combination of keyof typeof to get the keys in BarcodeFormat and do type casting on format.
QUESTION
I've been trying to fix this for weeks but failed, when I click on login (indicated with the id "lin") to open a new activity the app crash, i don't know if it's a problem with the Intent or something else, here is the code. The manifest should be ok so I think it's a problem in the MainActivity with Intent ab. The other activity is called Qrcode. I tried to change appcompatactivty to activity but didn't work, i don't really know what to do.
Edit: I posted the code of the qrcode activity, i got it from the answers of this question : Android, How to read QR code in my application?, only for educational purpose of course.
Edit 2: logcat posted, sorry for any issues with asking this question, it's the first question i ask here.
Logcat
...ANSWER
Answered 2021-Jun-03 at 17:42ur code in MainActivity seems ok and I think don't have any problem. In my opinion your Qrcode Activity has some bugs in it, like onCreate method, you should see the Logcat logs in android Studio, btw u can attach the Qrcode activity codes here, it is really helpful. another way to find the bug is by using the try-catch in your code and log the exception

When I check the external libraries in my Android Studio Project, I see duplicated libraries in different versions.
Is there any way to find out the reason.
I definitely do not add more than one dependency. But not sure, what causes this. This is my build.gradle file;

below is my ar code
...ANSWER
Answered 2021-Feb-23 at 09:08I recommend trying the existing Augmented Images feature in ARCore
What you think is a QR code, the AR software sees as a fiducial marker. These markers need to known beforehand. For example in the video on the ARCore page, the painting is a fiducial marker which allows the 3D image to be overlaid.
The ARCore feature I linked to supports up to 1000 reference images/markers per marker database and you can create and use new predefined marker databases.
As long as you know what QR codes will have 3D effects, you can prepare them in a marker database.
If you want/need to have dynamic QR code with ARCore, I would suggest trying to create fiducial around/next to the QR code so that you can scan and then hand off to AR Core to generate the 3d image, but may not work as QR code may be mixed in with the fiducial both need white space to work.
If you can't use ARCore, then you are in the world of OpenCV and various scene engines (3D renderers) like Ogre or you can draw the AR scene in OpenGL ES.
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 });

Code:
...ANSWER
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
