W: the width of Code 11, controlled by property BarCodeWidth

X (X ≥ 1 pixel): the width of a module bar, controlled by property X

Q (Q ≥ 10X): the width of the quiet zone, related to property LeftMargin & RightMargin

• Code 11 Barcode Data Encoding for VB.NET Barcode Generator

After Code 11 VB.NET Generator installation, get it ready in VB.NET by placing the following statement:

Dim code11 As OnBarcode.Barcode.Linear

code11 = New OnBarcode.Barcode.Linear

code11.Type = OnBarcode.Barcode.BarcodeType.CODE11

UOM

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:

code11.UOM = OnBarcode.Barcode.UnitOfMeasure.PIXEL

X & Y

Property X (Type: Float; Default: 1) and Property Y (Type: Float; Default: 60) are used in Code 11 barcode symbol size setting. X is for the module width setting, and Y controls the height of the bar.

Sample usage:

code11.X = 2

code11.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:

code11.BarcodeHeight = 60

code11.BarcodeWidth = 175

AutoResize

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 Code 11 100% compatible with its symbology specification. See Code 11 Barcode Size in VB.NET to know more usage of AutoResize.

Sample usage:

code11.X = 2

code11.BarcodeHeight = 60

code11.AutoResize = True

TopMargin, BottomMargin, LeftMargin, & RightMargin

Using Code 11 VB.NET Generator, a quiet zone with 10X width will be generated automatically at each side of the Code 11. 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:

code11.TopMargin = 10

code11.BottomMargin = 10

code11.LeftMargin = 10

code11.RightMargin = 10

TextMargin

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 Code 11 bar code and the human readable text below the barcode.

Sample usage:

code11.TextMargin = 10
