How to Use C# to Set Colorful Barcode Image
Top
Colorful barcode image setting in C# class is very simple. You can set the image functions background color, foreground color, and human readable text color in your C# barcode system. Just follow the quick C# barcode manual below.
Firstly, please downlolad the toolkit and add .NET barcode generator dll into your C# project reference. In the following example, we use OnBarcode.Barcode.WinForms.dll and Code 39 is the sample barcode type with alphanumeric sample string.
   Linear code39 = new Linear();
code39.Type = BarcodeType.CODE39;
code39.Data = "3333999";
code39.X = 1;
code39.Y = 76;
code39.LeftMargin = 10;
code39.RightMargin = 10;

// Customize Code 39 image color
code39.BackColor = Color.Yellow;
code39.ForeColor = Color.Blue;
code39.TextColor = Color.Black;

// Draw Code 39 barcode to C:\
code39.drawBarcode("C://csharp_code39.png");
How to Use C# to Get Transparent Barcode Images
Top
This .NET barcode generator suite enables users to customize barcode image background to be transparent. Currently, barcode image in png and gif file format supports transparent background setting.An EAN-13 barcode encoding 13 numeric string value is sampled.
Please copy the following Visual C# demo code to your project for a transparent barcode symbol implementation. You can store the scannable barcode images in database with further C# coding.
   Linear barcode = new Linear();

barcode.Type = BarcodeType.EAN13;

barcode.Data = "123456789012";

barcode.BackColor = Color.Transparent;

barcode.drawBarcode("c://csharp_ean13.png");
How to Use C# to Encode Image Formats (JPEG, PNG, GIF, BMP, TIFF)
Top
Users can use C# code to generate a barcode image and encode it into several image file format, namely JPEF/JPG, PNG, GIF, BMP/Bitmap and TIFF. Please see as below. (UPC-A is the sample barcode type encoding 12 number digit with check character automatically added).
Developers can adjust other barcode settings, in order to enlarge barcode picture to fixed size in C# by setting width/height, manage barcode label rotation, set unit of measure to centimeter/pixel, or define encrypted barcode color.
   Linear upc_a = new Linear();
upc_a.Type = BarcodeType.UPCA;
upc_a.Data = "12345678901";

// Encode UPC-A barcode into jpeg file format and save it to C:\
upc_a.Format = System.Drawing.Imaging.ImageFormat.Jpeg;
upc_a.drawBarcode("c://csharp_upca.jpeg");

/*
Encode UPC-A barcode into png, gif, bmp or tiff file format:
upc_a.Format = System.Drawing.Imaging.ImageFormat.Png;
upc_a.drawBarcode("c://csharp_upca.png");

upc_a.Format = System.Drawing.Imaging.ImageFormat.Gif;
upc_a.drawBarcode("c://csharp_upca.gif");

upc_a.Format = System.Drawing.Imaging.ImageFormat.bmp;
upc_a.drawBarcode("c://csharp_upca.bmp");

upc_a.Format = System.Drawing.Imaging.ImageFormat.tiff;
upc_a.drawBarcode("c://csharp_upca.tiff");
