Architecture

The diagram below demonstrate basic SDK components usage concept.

To access barcode recognition functionality your application will communicate with SDT Barcode runtime components through programming interface (SDK library). Programming interface is programming language dependent. Both Libraries and runtime components are included into SDK. Runtime components must be included into your application setup for distribution to your clients as a part of your software application. Seee below which types of runtimes can be used from certain programming languages. The core SDK component is Barcode Reader Engine. On input the Barcode Reader Engine receive image file or image data allocated in memory. The image can be either scanned document or captured photo. The Engine reads the input and recognize known types of barcodes on it. On output the Engine returns a list of detected barcode values and properties such as position on image, barcode type etc.

Runtimes and Supported Programming languages

• Java library Android(sdt-barcode-android.jar): Java

The following diagram demonstrate linkage between various libraries and a language/technology it is mainly made for.

Android JAR and JNI library

sdt-brc-android.jar - Java class library.
libjsdtbarcode-arm.so - Android JNI shared library used in conjunction with sdt-brc-android.jar for integration barcode recognition into Android applications.
