Support and trial license email: nuget@bardecode.com

Basic use:

barcode = new SoftekBarcodeNetStandard.BarcodeReader();

// If using PDF then set path to gs

barcode.gsPath = @"/path/to/gs";

nBarCode = barcode.ScanBarCode("inputfile.tif"); // Can be TIF, JPG or PDF

for (int i = 1; i ⇐ nBarCode; i++)

   value = barcode.GetBarString(i);

Setting more options and getting more results:

using (barcode = new SoftekBarcodeNetStandard.BarcodeReader())
{

    // Enter your license key here
    // You can get a trial license key from nuget@bardecode.com
    // Example:
    // barcode.LicenseKey = "MY LICENSE KEY";

    // Turn on the barcode types you want to read.
    // Turn off the barcode types you don't want to read (this will increase the speed of your application)

    barcode.MultipleRead = true;

    // Noise reduction takes longer but can make it possible to read some difficult barcodes
    // When using noise reduction a typical value is 10 - the smaller the value the more effect it has.
    // A zero value turns off noise reduction.

    // DeskewMode controls the way in which the toolkit handles skewed documents. At the default level (2) 
    // the toolkit will deskew at the main angle of the whole image. If the bar code is at a different angle
    // to the rest of the image then try 3. For more complex images try values from 4 to 6.
