Deploy your application to your preferred target or device, including a physical computer, Cloud VM, container, or microservice.

Read 1D barcodes from a page

This example reads code 39 and code 128 barcodes. Set barcode types used in your application. Setting reader.Auto1D=true; automatically finds barcode type, but it is slower and is not recommended for production.

using Inlite.ClearImageNet;

void ReadBarcode1D_page(string fileName, int page) {
    try {
        using(BarcodeReader reader = new BarcodeReader()) {
            reader.Code39 = true; reader.Code128 = true; 
            // reader.Auto1D = true;
            Barcode[] barcodes = reader.Read(fileName, page);
            foreach(Barcode barcode in barcodes)
                Console.WriteLine($"Barcode type: {barcode.Type}   Text: {barcode.Text}");
            }
        }
    catch(Exception ex) { Console.WriteLine("Exception: " + ex.ToString()); }
    }

Read 2D Barcode from a page

This example reads PDF417, DataMatrix, and QR code. 2D barcodes might contain binary data available in Barcode.Data property.

using Inlite.ClearImageNet;

void ReadBarcode2D_page(string fileName, int page) {
    try {
        using(BarcodeReader reader = new BarcodeReader()) {
            reader.Pdf417 = true;  // <= Read PDF417 barcodes
            // reader.DataMatrix = true;
            // reader.QR = true;
            Barcode[] barcodes = reader.Read(fileName, page);
            foreach(Barcode barcode in barcodes) 
                Console.WriteLine($"Barcode type: {barcode.Type}   Text: {barcode.Text}");
            }
        }
    catch(Exception ex) { Console.WriteLine("Exception: " + ex.ToString()); }
    }

Read Postal Barcodes from a page

This example reads Postal Barcodes from an image file page.

using Inlite.ClearImageNet;

void ReadPostal_page(string fileName, int page) {
    try {
        using(BarcodeReader reader = new BarcodeReader()) {
            reader.FourState = true;  //  <= Read postal barcodes
            Barcode[] barcodes = reader.Read(fileName, page);
            foreach(Barcode barcode in barcodes) {
                switch(barcode.Type) {
                    case BarcodeType.UspsIntelligentMail:
                        Console.Write(" US Intelligent Mail"); break;
                    case BarcodeType.BpoPostcode:
                        Console.Write("UK Royal Mail"); break;
                    case BarcodeType.AustralianPost:
                        Console.Write("Australian Mail"); break;
                    case BarcodeType.SingaporePost:
                        Console.Write("Singapore Mail"); break;
                    case BarcodeType.FourState:
                        Console.Write("ForState "); break;
                    }
                Console.WriteLine("   Text: " + barcode.Text);
                }
            }
        }
    catch(Exception ex) { Console.WriteLine("Exception: " + ex.ToString()); }
    }

Read Driver's License barcode

This example reads the Driver's License barcode from an image file page.

using Inlite.ClearImageNet;

void ReadDriverLicBarcode_page(string fileName, int page) {
    try {
        using(BarcodeReader reader = new BarcodeReader()) {
            reader.DrvLicID = true;  
            Barcode[] barcodes = reader.Read(fileName, page);
            foreach(Barcode barcode in barcodes) {
                Inlite.Data.DLDecoder decoder = new Inlite.Data.DLDecoder();
                if(decoder.Decode(text) != "") {
                    Console.WriteLine("last: " + decoder.last);
                    Console.WriteLine("first: " + decoder.first);
                    Console.WriteLine("middle: " + decoder.middle);
                    Console.WriteLine("dob: " + decoder.dob);
                    Console.WriteLine("eyes: " + decoder.eyes);

                    Console.WriteLine("state: " + decoder.state);
                    Console.WriteLine("postal: " + decoder.postal);
                    Console.WriteLine("country: " + decoder.country);
                    Console.WriteLine("id: " + decoder.id);

                    Console.WriteLine("expires: " + decoder.expires);
                    }
                }
            }
        }
    catch(Exception ex) { Console.WriteLine("Exception: " + ex.ToString()); }
    }

Read from a multi-page image file

This example reads barcodes from a single-page file or all pages of a multi-page image file.

using Inlite.ClearImageNet;

void ReadBarcode1D_file(string fileName) {
    try {
        using(BarcodeReader reader = new BarcodeReader()) {
            reader.Code39 = true; reader.Code128 = true;
            Barcode[] barcodes = reader.Read(fileName); // <== Read from all pages
            foreach(Barcode barcode in barcodes) 
                Console.WriteLine($"Barcode type: {barcode.Type}  Barcode page: {barcode.Page}  Text: {barcode.Text}");
            }
        }
    catch(Exception ex) { Console.WriteLine("Exception: " + ex.ToString()); }
    }

Read from a stream

This example reads barcodes from a stream. The stream contains the content of a single image file. For example, if a file is stored in a database.

using Inlite.ClearImageNet;

void ReadBarcode1D_stream(Stream stream) {
    try {
        using(BarcodeReader reader = new BarcodeReader()) {
            reader.Code39 = true; reader.Code128 = true;
            Barcode[] barcodes = reader.Read(stream); // <== read from a stream
            foreach(Barcode barcode in barcodes) 
                Console.WriteLine($"Barcode type: {barcode.Type}  Barcode page: {barcode.Page}  Text: {barcode.Text}");
            }
        }
    catch(Exception ex) { Console.WriteLine("Exception: " + ex.ToString()); }
    }

Image Processing - Repair image page

This example uses some of the most popular image-processing functions. In a production application, the specific sequence of functions should be selected based on specific application needs. 

using Inlite.ClearImageNet;

static void RepairPage(ImageEditor editor) {
    editor.AutoDeskew();
    editor.AutoRotate();
    editor.AutoCrop(10, 10, 10, 10);     // Crop to 10 pixels on each side
    // editor.AdvancedBinarize();        // Convert to bi-tonal an image with complex background patterns
    editor.ToBitonal();
    editor.BorderExtract(BorderExtractMode.deskewCrop); // Deskew and crop based on black border
    editor.RemovePunchHoles();
    editor.SmoothCharacters();
    editor.CleanNoise(3);               // Clean black noise of 3 pixels
    // editor.CleanNoise    // Clean black and white noise            
    //    (CleanNoiseFlags.black | CleanNoiseFlags.white, 3, 3, 10); 
    editor.ReconstructLines(LineDirection.horzAndVert);
    }

void Repair_page(string fileName, int page, string fileOut) {
    try {
        using(ImageEditor editor = new ImageEditor()) {
            editor.Image.Open(fileName, page);
            // Do image repair
            RepairPage(editor);
            // Save results
            editor.Image.SaveAs(fileOut, Inlite.ClearImage.EFileFormat.ciEXT);
            }
        }
    catch(Exception ex) { Console.WriteLine("Exception: " + ex.ToString()); }
    }

Image Processing - Repair all images in a multi-page file

This example repairs all images in a multi-page file and saves the result in the fileOut file.

using Inlite.ClearImageNet;

private static void _OnEditPage(object sender, EditPageEventArgs e) {
    // e.cancel = true;    // Abort file processing 
    // e.skipPage = true;  // Remove this page from the output
    RepairPage(e.Editor);  // See this method in a single page example
    }

void Repair_file(string fileName, string fileOut) {
    try {
        using(ImageEditor editor = new ImageEditor()) {
            bool ret = editor.Edit(fileName, _OnEditPage, fileOut, ImageFileFormat.outputFileExtension, true);
            }
        }
    catch(Exception ex) { Console.WriteLine("Exception: " + ex.ToString()); }
    }

Image Processing - Repair all images in a stream

This example repairs all images in an input stream and saves the output stream using a specified file format. Streams contain the content of a single image file. For example, if a file is stored in a database.

using Inlite.ClearImageNet;

private static void _OnEditPage(object sender, EditPageEventArgs e) {
    RepairPage(e.Editor);  // See this method in a single page example
    }

Stream Repair_stream(Stream stream, ImageFileFormat output_format) {
    try {
        using(ImageEditor editor = new ImageEditor()) {
            MemoryStream msOut = editor.Edit(stream, _OnEditPage, output_format);
            return msOut;
            }
        }
    catch(Exception ex) { Console.WriteLine("Exception: " + ex.ToString()); return null; }
    }
