How to Use VB.NET MSI Plessy Generator Size Setting Properties

VB.NET MSI Plessy Generator provides VB.NET developers with a full set of properties for MSI Plessy size setting.

Input the following VB Code to use VB.NET MSI Plessy Generator where MSI Plessy bar code image is needed.

Dim msi As KeepAutomation.Barcode.Bean.BarCode

msi = New KeepAutomation.Barcode.Bean.BarCode()

msi.Symbology = KeepAutomation.Barcode.Symbology.MSI

Input a string value for CodeToEncode, which will be encoded as data in your MSI Plessy. Pay attention to the data encoding instruction for MSI Plessy.

msi.CodeToEncode = "111111"


Property BarcodeUnit is in control of unit of measure. Before setting the bar width and image size, you should know for sure all the properties in the coming passages are based on the unit of measure. BarcodeUnit defaults as Pixel, and you can change it to cm or inch.

msi.BarcodeUnit = BarcodeUnit.Pixel


Property X (Float; Default: 1) is used in MSI Plessy module bar width setting. Try to set X using VB.NET code as follows:

msi.X = 2

Now, the width of a bar in MSI Plessy has been changed from 1 pixel (as default) to 2 pixel. You can make it even greater if wider bars are in need.


Property Y (Float; Default: 50) sets the bar height of the MSI Plessy.

msi.Y = 40

The width of bars in MSI Plessy has been changed from 50 pixels (as default) to 40 pixels. You can make it even greater or smaller.

BarCodeHeight and BarCodeWidth

VB.NET MSI Plessy Generator is also equipped with functional properties BarCodeHeight (Float; Default: 0) and BarCodeWidth (Float; Default: 0) to set the size of the whole MSI Plessy bar code image.

msi.BarCodeHeight = 70

msi.BarCodeWidth = 175

Note: If the setting of image size conflict with the settings in bar width or bar height, you can enable AutoResize to make the generated MSI Plessy compatible with MSI Plessy barcode specification.

TopMargin, BottomMargin, LeftMargin, and RightMargin

MSI Plessy VB.NET Generator will generate a quiet zone at each end of the MSI Plessy symbol automatically. The auto-generated quiet zone is 10X width. You can increase width of quiet zone by increasing the value of properties LeftMargin (Float; Default: 0) and RightMargin (Float; Default: 0). Also, the height of the image can be increased using TopMargin (Float; Default: 0) and BottomMargin (Float; Default: 0).

msi.TopMargin = 10

msi.BottomMargin = 10

msi.LeftMargin = 10

msi.RightMargin = 10


Property TextMargin (Float; Default: 6 pixel) controls the width of space between MSI Plessy bar code and the human readable text below the barcode.

msi.TextMargin = 10
