Camera preview is compressed about mobilevisionbarcodescanner HOT 8 OPEN

@KingsMentor
I am with same problem, I realized that when init the screen the camera preview is compressed, however I go to other screen and back to camera preview without killing the instance the preview, the screen is normal, does not get compressed

Edit:
This code solved the problem for me.
barcodeCapture = childFragmentManager.findFragmentById(R.id.fragment) as BarcodeCapture? barcodeCapture?.setRetrieval(this) barcodePreview = barcodeCapture?.view?.findViewById(R.id.preview) as? CameraSourcePreview barcodeCapture?.view?.post { barcodePreview?.requestLayout() }

@JDSCaram 's suggestion fixed the issue for me. Here is a java code equivalent:
final View barcodePreview = barcodeCapture.getView().findViewById(R.id.preview);
barcodeCapture.getView().post(new Runnable() {
@OverRide
public void run() {
barcodePreview.requestLayout();
}
});

@KingsMentor Any update?

@darkkillen what version of the library are you using. Kindly confirm if it is 2.0.3

from mobilevisionbarcodescanner.

@KingsMentor I am having this same issue in 2.0.3
Maybe Actionbar is causing this? Not sure though

from mobilevisionbarcodescanner.

@KingsMentor Please explain why the latest release version 2.0.3 and the library master branch are not the same.
I tested the sample app from the project repo (after changing layout to fullscreen with toolbar) and the preview is not compressed.
When I replaced implementation project(':barcodescanner') with implementation 'xyz.belvi.mobilevision:barcodescanner:2.0.3' to test latest library release version the preview was compressed again.
I even reverted back to the sample app and only changed gradle to use the release library instead of the project library and the preview was also compressed.

I hope this information might help finding the source of the issue and releasing a fix for it.

Hey @KingsMentor,

Thank you for your library!

I have encountered the same problem. It occurs on phones with non usual aspect ratios like the huawai p20 pro and the samsung s9+. When i check the code i see that it uses the displayMetrics for the screen height and width, but i believe it should use the preview height and width. This will make the camera view stretch. I hope this information in combination with the following article can help you further in solving this problem.

Hi, i'm trying this but i continue to see the stretched preview. Is there any other way to solve it?
