Setting EAN-8 Barcode Size in C#Adjusting EAN-8 Barcode Size in C#
In order to help developers understand how to set EAN-8 barcode size in C#, OnBarcode gives some examples as bellow.
Therefore, developers can easily control the barcode size with our EAN-8 Generators: How to generate, print barcode using .NET, Java sdk library control with example project source code free download:

Setting EAN-8 Barcode Size in C#Basic information you should know
In GS1 specification, EAN-8 barcode width, W (measured in pixel), can be computed as below.
Note that, our EAN-8 barcode generators automatically set the value of each quiet zone 10X [Q (L) = 10X, Q (R) = 10X], then the respective value of W in above calculation should be 87X, (107X + 15), (134X + 15). As for EAN-8 barcode height, our generators will automatically adjust it in accordance with GS1 specification. Meanwhile, it is user-defined as well, and customers may set it through Top and Bottom Margin settings.
Three Situations for EAN-8 Barcode Size Setting in C#
Setting barcode size in C# EAN-8 Barcode Generator may have three situations.
Situation 1:
To create an EAN-8 barcode with a minimum X, please do this: Eg1. You may set in C# EAN-8 barcode generator like this:
ean8.Data = "1234567";
ean8.X = 3;
ean8.AutoResize = false;
Other properties: default;
The created EAN-8 barcode image is:
If a Two-digit or Five-digit Add-On barcode is added to EAN-8 barcode, you are supposed to select the barcode type (EAN8_2/_5) firstly, and then set the supplement data. For example, you may set:
ean8.Type = BarcodeType.EAN8_2;
ean8.Data = "1234567";
ean8.SupData = "89";
ean8.X = 3;
ean8.AutoResize = false;
Other properties: default;
You will generate an EAN-8 barcode:
Situation 2:
To create an EAN-8 barcode with a fixed barcode image width (W), and need to draw maximum barcode module (X) as possible, please do this: Eg2. You may set in C# EAN-8 barcode generator like this:
ean8.Data = "1234567";
ean8.BarcodeWidth = 180;
ean8.AutoResize = ture;
Other properties: default;
The created EAN-8 barcode image is:
 In the above EAN-8 barcode image, the maximum bar module (X) is 2 pixel.
If a Two-digit or Five-digit Add-On barcode is appended to EAN-8 barcode, you need to choose the barcode type (EAN8_2/_5) firstly, and then set the supplement data. For instance, you may set:
ean8.Type = BarcodeType.EAN8_5;
ean8.Data = "1234567";
ean8.SupData = "89012";
ean8.BarcodeWidth = 180;
ean8.AutoResize = true;
Other properties: default;
You will generate an EAN-8 barcode:
 Now, the maximum value of bar module (X) is 1 pixel.
Situation 3:
To create an EAN-8 barcode with minimum X and fixed barcode image width (W), please do this. Eg3. You may set in C# EAN-8 barcode generator like this:
ean8.Data = "1234567";
ean8.X = 2;
ean8.BarcodeWidth = 220;
ean8.AutoResize = false;
Other properties: default;
The created EAN-8 barcode image is:
Note that, GS1 specification indicates that there will be a minimum barcode image width as long as you set bar module (X) value.
However, our EAN-8 barcode generation libraries automatically set the value of each quiet zone 10X [Q (L) = 10X, Q (R) = 10X]). In this case, the respective value of W in above calculation should be 87X, (107X + 15), (134X + 15).
Thereby, 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 instance, you set:  If your BarcodeWidth setting is 291 pixel, which is larger than the minimum barcode width (261 pixel), the created EAN-8 barcode image will be like below. And extra 30 pixel space will be added to the left and right side of barcode image.  |
