How to reduce cpu usage with barcode reader sdk in C# with ByteScout Data Extraction Suite

Learning is essential in computer world and the tutorial below will demonstrate how to reduce cpu usage with barcode reader sdk in C#

We made thousands of pre-made source code pieces for easy implementation in your own programming projects. What is ByteScout Data Extraction Suite? It is the set that includes 3 SDK products for data extraction from PDF, scans, images and from spreadsheets: PDF Extractor SDK, Data Extraction SDK, Barcode Reader SDK. It can help you to reduce cpu usage with barcode reader sdk in your C# application.

These C# code samples for C# guide developers to speed up coding of the application when using ByteScout Data Extraction Suite. IF you want to implement the functionality, just copy and paste this code for C# below into your code editor with your app, compile and run your application. Check C# sample code samples to see if they respond to your needs and requirements for the project.

You can download free trial version of ByteScout Data Extraction Suite from our website with this and other source code samples for C#.

Program.cs

            Reader reader = new Reader();
            reader.RegistrationName = "demo";
            reader.RegistrationKey = "demo";

            /*
             If you are reading barcodes from PDF then you may reduce CPU and RAM load using the following approach:
                - instead of using All1D or All2D barcode types, set it to the specific types you have in your documents like PDF417 or Code 39. You may set multiple barcode types if you need to
                - reduce PDF rendering resolution to 200-150 dpi (depends on your document)
                - set specific pages to read barcodes from. If you have barcodes on 2 first pages only then change the code to read barcodes from first 2 pages only.
                - if barcodes are always located / printed in the same corner then also specify the area to read from instead of whole page for scanning
