C# AFORGE.NET İLE GÖRÜNTÜ İŞLEME-5 Barkod Okutma (AFORGE + ZXING)

AFORGE.NET İle formumuzdaki picturebox'a aktardığımız webcam görüntüsünden ZXING ile barkod okuma işlemini yaptırdık. Kodlar aşağıdaki gibidir. Manage NuGet Packages kısmından AFORGE.NET ve ZXING kütüphanelerini eklemeyi unutmayınız!
