Hello,

Thanks for your inquiry.
Please add Spire.Barcode.dll as a reference to your project, then call the below method to read your barcode.

string[] barcodes = Spire.Barcode.BarcodeScanner.Scan(Bitmap image, BarCodeType barcodeType);

Best regards,
Amy

Does the Barcode Reader only read images or is it able to use the built-in camera to read actual barcodes? If it doesn't read actual barcodes, do you have a dll that will allow me to use my built-in tablet camera to take a picture?

ANY help would be greatly appreciated.

Thanks.

Hello,

Sorry that our Spire.Barcode can only scan images and doesn’t provide any dll to control the built-in camera. You need to code to control the build-in camera.
If you have any questions, welcome to get it back to us.

Thanks and Regards,
