How to Generate, Resize Code 39 Images in C# Class
Copy the following free C#.NET sample code onto your project to produce a Code 39 barcode image
BarCode code39= new BarCode();
code39.Symbology = KeepAutomation.Barcode.Symbology.Code39;
code39.CodeToEncode = "CODE39";
Code 39 Barcode Unit
The default value for Code 39 barcode unit is pixel for KA.Barcode Generator for .NET Suite, so all the parameters below, like X dimension, barcode width, etc are measured in pixel. To create Code 39 using Cm or Inch, simply copy the C# demo code below.
code39.BarcodeUnit = BarcodeUnit.Cm;

Code 39 X Dimension (Module Width)
Code 39 X dimension is the width of the narrow element, i.e. width of the module bar. Default value is 1 pixel. Users can adjust this parameter according to your needs. The greater the X dimension, the wider the bar code image is.
Code 39 WideNarrowRatio
Code 39 WideNarrowRatio stands for the ratio of Code 39 wide bar width to Code 39 narrow bar width, which is valid from 2 to 3 inclusive, as is specified in Code 39 standard. For example, if you set X to 2 pixels, and WideNarrowRatio to 3, then your generated Code 39 wide bar width would be 6 pixel. You can easily adjust this dimension through the following C# code.
code39.X = 2;
code39.WideNarrowRatio = 3;
Code 39 Y Dimension (Bar Height)
Code 39 Y dimension is the height of Code 39 bar, as well as the height of the whole code 39 bar code image. This is a float value is 50 pixels by default. You can adjust Code 39 bar height through the C#.NET code below.
code39.X = 2;
code39.WideNarrowRatio = 3;
Code 39 I Dimension
I Dimension is the intercharacter space in a generated Code 39 bar code image. This property is float with a default value 1, which is the minimum value as is required in Code 39 specification. It means the intercharacter space is equal to X. For example, if you set X to 2 pixels, and I dimension to 1.5, then the intercharacter space is actually 1.5 times of X dimension, which finally comes to 3 pixels.
Code 39 Barcode Quiet Zones / Margins
It is clearly defined in the ISO/IEC 16388 Code 39 bar code symbology specification that the quiet zones / margins at the left and right side of a Code 39 image shall be a minimum of 10X (10 times the width of the module bar). KeepAutomation C# Code39 generator will automatically calculate and add this 10X quiet zones for you. If you want to add more margins on four sides, just follow the codes.
code39.LeftMargin = 3;
code39.RightMargin = 3;
code39.TopMargin = 3;
code39.BottomMargin = 3;
Code 39 BarCode Height and BarCode Width
With KA.Barcode Generator for .NET Suite, users can also customize Code 39 barcode width and barcode height easily using Visual C#.NET programming. You can copy the C# demo code below into your projects for testing.
code39.BarCodeHeight = 60;
code39.BarCodeWidth = 175;
Please note that once you have input Code 39 data and adjusted X dimension, there will be a minimum image width according to the encoding pattern specified in the standard. Thus if the barcode width you are trying to set is less than that minimum value, this value will be considered to be invalid.
KA.Barcode Generator for .NET Suite will generate a valid Code 39 image with the minimum barcode width. You will have to either assign a greater value to BarcodeWidth or set X dimension smaller.
Code 39 TextMargin
Code 39 Text Margin is the margin between the Code 39 human readable text and the bottom of the bars. Default is 6 pixels. You can simply adjust this parameter through the following setting.
