iOS Question [B4X] [B4XPages] Barcode Reader

[imbault]

Hi Team,

On the B4i Barcode Reader, the barcode scanner works like a charm,

I just want to take the picture on the preview panel

Thanks a lot

Try this:
- Set the preview panel type to be B4XView and call Panel.Snapshot.

I haven't tried it.

Getting the preview image from the camera will be difficult.

Thank you @Erel ,

I tried creationg Page2 with an Public ImageView1 As B4XView
then:

Private Sub StopCamera
    Capturing = False
    btnStartStop.Text = "Start"
    'camEx.TakePicture
    pnlPreview.Visible = False
    #if B4A
    If camEx.IsInitialized Then
        camEx.Release
    End If
    #Else If B4i
    scanner.Stop
    dim bmp As B4XBitmap = pnlPreview.Snapshot
    
    If bmp.Height > 0 Then
        page2.ImageView1.SetBitmap(bmp)
        B4XPages.ShowPage("page 2")
    End If
    #end if
End Sub

And it doesn't show nothing...
is there any mistake?

Thanks

I tried it now. It will not work.

Any workaround?

You can try to close the barcode scanner and open the camera yourself with LLCamera.

The iBarcode library combines camera preview and barcode reading together. You can try the decoupled version: [B4X] [B4XPages] Dynamsoft Barcode Reader - Cross-Platform Barcode/QR Code Decoding Library | B4X Programming Forum
