Setting EAN-13 Barcode Size in C#C# EAN-13 Barcode Size Setting
OnBarcode offers explanation of how to set EAN-13 barcode size in C# with our Barcode Generators for EAN-13. Definitely, users are entitled to control EAN-13 image size using the products below.

Setting EAN-13 Barcode Size in C#Basic information you should know
According to GS1 specification, the barcode width of EAN-13, W (measured in pixel), is easy to be calculated.
In Our EAN-13 generators, the value of each quiet zone is designed to be 10X [Q (L) = 10X, Q (R) = 10X].Therefore, the respective value of W in above calculation should be 115X, (135X + 15), (162X + 15). The height of EAN-13 barcode should conform to GS1 specification (25.9 millimeters). To make things easier, our EAN-13 barcode generators may automatically control the image height according to the specification. Certainly, the image height is user-defined and customers can adjust the barcode height through Top and Bottom Margin settings.
Three Situations for Setting EAN-13 Barcode Size in C#
Barcode size setting in C# EAN-13 Generator may have three situations.
Situation 1:
If you want to generate an EAN-13 barcode with a minimum X, please do this: Eg1. In C# EAN-13 generator, you set:
ean13.Data = "987654321098";
ean13.X = 2;
ean13.AutoResize = false;
Other properties: default;
The generated EAN-13 barcode image is:
If EAN-13 needs a supplement data (2 or 5 digits), you should firstly choose the barcode type (EAN13_2/EAN_5), then set the supplement data. For instance, you set:
ean13.Type = BarcodeType.EAN13_2;
ean13.Data = "987654321098";
ean13.SupData = "76";
ean13.X = 2;
ean13.AutoResize = false;
Other properties: default;
You will get an EAN-13 barcode:
Situation 2:
If you want to generate an EAN-13 barcode with a fixed barcode image width (W), and try to draw maximum barcode module (X) as possible, please do this: Eg2. In C# EAN-13 generator, you set:
ean13.Data = "987654321098";
ean13.BarcodeWidth = 300;
ean13.AutoResize = ture;
Other properties: default;
The generated EAN-13 barcode image is:
 In the above EAN-13 image, the bar module (X) is 2 pixel, which is the maximum bar module.
If EAN-13 has a supplement data (2 or 5 digits), please choose the barcode type (EAN13_2/EAN_5), and then set the supplement data. For example, you set:
ean13.Type = BarcodeType.EAN13_5;
ean13.Data = "987654321098";
ean13.SupData = "76543";
ean13.BarcodeWidth = 300;
ean13.AutoResize = ture;
Other properties: default;
You will get an EAN-13 barcode:
 Now, the maximum value of bar module (X) is 1 pixel.
Situation 3:
If you want to generate an EAN-13 barcode with minimum X and fixed barcode image width (W), please do this. Eg3. In C# EAN-13 generator, you set:
ean13.Data = "987654321098";
ean13.X = 3;
ean13.BarcodeWidth = 350;
ean13.AutoResize = false;
Other properties: default;
The generated EAN-13 barcode image is:
Note that, once you have set bar module (X) value, there will be a minimum barcode image width defined by GS1 specification.
In Our EAN-13 generators, the value of each quiet zone is default by 10X [Q (L) = 10X, Q (R) = 10X]), compatible with GS1 specification. And the respective value of W in above calculations should be 115X, (135X + 15), (162X + 15).
So if your BarcodeWidth value is less than the minimum barcode width, the barcode generator component will reset BarcodeWidth value to the minimum barcode width value.
For example, you set:  If your BarcodeWidth setting is 480 pixel, which is larger than the minimum barcode width (460 pixel), the generated EAN-13 barcode image will be like below. And extra 20 pixel space has been appended to the left and right side of barcode image.  |
