Draw Code 39 on Raster Image in C# Project

With the following Visual C# demo code, you are able to generate Code 39 on raster image files, including BMP, PNG, GIF, and JPEG formats. Below are some basic settings for Code 39. For more dimension settings, please refer to the complete property table below. You will be able to adjust barcode location on image, and control Code 39 size, resolution, checksum, orientation, color, and text, etc.

private static void AddBarcodeToImage(Linear barcode)
        {
            REImage image = new REImage(inputDirectory + "Sample.png");
            barcode.DrawBarcode(image, 150F, 150F);
            image.Save(ImageType.PNG, outputDirectory + "Sample_Barcode.png");
        }

Generate Code 39 with C# Code

RasterEdge offers free and accurate C# example code to create customized Code 39 on image and document files, by adjusting the properties listed above.

// create REImage on which you want to draw the barcode
REImage reImage = new REImage("c:/Sample.png");

Linear barcode = new Linear();// create a barcode
barcode.Type = BarcodeType.CODE39;// select barcode type
barcode.Data = "0123456ABCD";// set barcode data 

// Code 39 barcode size related
barcode.X = 1.0F;// set x
barcode.Y = 60.0F;// set y
barcode.BarcodeHeight = 60;
barcode.BarcodeWidth = 0;
barcode.BottomMargin = 0;
barcode.LeftMargin = 0;
barcode.RightMargin = 0;
barcode.BarAlignment = AlignmentHori.Left;
barcode.Resolution = 72;// set resolution
barcode.Rotate = Rotate.Rotate0;// set rotation
barcode.AddCheckSum = false;
barcode.UOM = RasterEdge.Imaging.Barcode.Creator.UnitOfMeasure.PIXEL;

// Code 39 colors
barcode.BackColor = System.Drawing.Color.White;
barcode.ForeColor = System.Drawing.Color.Black;

// Code 39 font style
barcode.TextFont = new Font("Arial", 9f, FontStyle.Regular);
barcode.TextColor = System.Drawing.Color.Black;
barcode.TextMargin = 6;
barcode.ShowText = true;

// Code 39 special
barcode.I = 1.0f;
barcode.N = 2.0f;
barcode.ShowStartStopInText = true;
barcode.ProcessTilde = false;

barcode.DrawBarcode(reImage, 0, 0);// draw barcode on REImage with location x and y

reImage.Save(ImageType.PNG, @"c:/barcode.png");

Create and customize Code 39 barcode in C# ASP.NET, WinForms apps

Using OnBarcode C# Barcode Generator library, you can apply the following two properties to customize the Code 39 bar and space width in C# application.

• N: Wide bar width vs narrow bar width ratio, 2.0 - 3.0 inclusive, default is 2.
• I: The space between 2 characters in code 39. This is a multiple of X (narrow bar width).

Here we will show how to customize the Code 39 barcode image below through properties N and I.

Code 39 Wide bar size vs Narrow bar size ratio (N)

You can apply the Code 39 wide bar vs narrow bar ratio through property N using C# Code 39 barcode generator library.

The property N valid value is from 2 to 3 (both inclusive). The default is 2.

barcode.N = 3;

Code 39 Intercharacter space (I)

You can apply the Code 39 inter characters space size through property I in C# class.

The property I is the space between 2 character bar modules, and it is a multiple of X (narrow bar module width). The default value is 1.0f.

barcode.I = 2;
