Intelligent Mail Barcode VB.NET Generator Size Setting Tutorial

After Intelligent Mail Barcode VB.NET Generator installation, get it ready in VB.NET by placing the following statement:

Dim onecode As OnBarcode.Barcode.Linear

onecode = New OnBarcode.Barcode.Linear

onecode.Type = OnBarcode.Barcode.BarcodeType.ONECODE


UOM is the controller of size setting unit. Pixel, Cm, and Inch are provided as its options. The default value of UOM is Pixel. For example, type the following statement to select Pixel as the unit of size setting measure:

onecode.UOM = OnBarcode.Barcode.UnitOfMeasure.PIXEL

X & Y

Property X (Type: Float; Default: 1) and Property Y (Type: Float; Default: 60) are used in Intelligent Mail Barcode barcode symbol size setting. X is for the module width setting, and Y controls the height of the bar.

Sample usage:

onecode.X = 2

onecode.Y = 70

BarCodeHeight & BarCodeWidth

Property BarCodeHeight (Type: Float; Default: 0) and Property BarCodeWidth (Type: Float; Default: 0) to set the size of the whole image.

Sample usage:

onecode.BarcodeHeight = 60

onecode.BarcodeWidth = 175


When the value of X, Y, BarCodeWidth, and BarCodeHeight conflict with each other, Property AutoResize (Type: bool; Default: False) should be enabled to solve the problem and make the Intelligent Mail Barcode 100% compatible with its symbology specification. See Intelligent Mail Barcode Barcode Size in VB.NET to know more usage of AutoResize.

Sample usage:

onecode.X = 2

onecode.BarcodeHeight = 60

onecode.AutoResize = True

TopMargin, BottomMargin, LeftMargin, & RightMargin

Using Intelligent Mail Barcode VB.NET Generator, a quiet zone with 10X width will be generated automatically at each side of the Intelligent Mail Barcode. When wider quiet zone is needed, you can increase the value of properties LeftMargin (Type: Float; Default: 0) and RightMargin (Type: Float; Default: 0). You can also create margins using TopMargin (Type: Float; Default: 0) and BottomMargin (Type: Float; Default: 0).

Sample usage:

onecode.TopMargin = 10

onecode.BottomMargin = 10

onecode.LeftMargin = 10

onecode.RightMargin = 10


Human readable text are required in almost every linear barcode symbology. Property TextMargin (Type: Float; Default: 6 pixel) is used to set the space between Intelligent Mail Barcode bar code and the human readable text below the barcode.
