VB.NET Imaging - VB Codabar Generator

VB Codabar Image Generator Overview

RasterEdge barcode generating SDK in VB.NET creates both linear and 2D barcode graphics with accuracy and high speed. The barcodes generated are printable and scannable with our barcode scanner application or any other barcode reading software. Codabar is one of barcode symbologies which can be encoded by our VB.NET barcode generating component. In case developers and users need barcode scanner for reading and decoding, RasterEdge Image SDK for VB.NET provides you Codabar Reader Add-on. And for developers interested in C# project, please refer to C# Codabar Barcode Generator and C# Codabar Barcode Reader. RasterEdge DocImage SDK for .NET provides professional and accurate Codabar generating component to quickly and easily write Codabar on images and documents, including image formats GIF, BMP, PNG, JPEG, and PDF, (Multi-page) TIFF, and Microsoft Office Word, Excel and PowerPoint documents. As long as you are using .NET 2.0 or above, and you have installed Visual Studio 2005 or later, you can easily draw and add readable Codabar in Visual VB Class Library, ASP.NET web and Windows applications. vb.net compress pdf file size, edit pdf c#, vb.net print form to pdf, itextsharp split pdf vb.net, convert pdf to jpg c# codeproject, convert pdf to text vb.net, vb.net extract image from pdf.

Why Choose Codabar Barcode in VB.NET Project

Codabar barcode symbology is the oldest barcode, commonly used in libraries, blood banks, shipping industries and other information processing applications. It allows 16 digits, 10 numeric digits(o-9), 6 special non alpha characters and 4 start/stop variable characters. And it holds more information compared with other barcode types. Codabar bar code does not require a check digit compulsorily, however, we may need Codabar check digit for high-quality barcode scanning in some cases. Considerately, our VB.NET Codabar generator designs optional check digit function for user's security consideration.

VB Code to Adjust Codabar Parameters

For all the above properties, we have demonstrated here the complete Visual VB sample codes. Developer can simply copy to your .NET program to print Codabar on your target images or documents.

// create REImage on which you want to draw the barcode
REImage reImage = new REImage("c:/Sample.png");

Linear barcode = new Linear();// create a barcode
barcode.Type = BarcodeType.CODABAR;// select barcode type
barcode.Data = "112233445566";// set barcode data 

// Codabar barcode size related
barcode.X = 1.0F;// set x
barcode.Y = 60.0F;// set y
barcode.BarcodeHeight = 60;
barcode.BarcodeWidth = 0;
barcode.BottomMargin = 0;
barcode.LeftMargin = 0;
barcode.RightMargin = 0;
barcode.BarAlignment = AlignmentHori.Left;
barcode.Resolution = 96;// set resolution
barcode.Rotate = Rotate.Rotate0;// set rotation
barcode.AddCheckSum = true;

// Codabar colors
barcode.BackColor = System.Drawing.Color.White;
barcode.ForeColor = System.Drawing.Color.Black;

// Codabar font style
barcode.TextFont = new Font("Arial", 9f, FontStyle.Regular);
barcode.TextColor = System.Drawing.Color.Black;
barcode.TextMargin = 0;
barcode.ShowText = true;

// Codabar special
barcode.CodabarStartChar = CodabarStartStopChar.A;
barcode.CodabarStopChar = CodabarStartStopChar.A;
barcode.N = 2.0f;

barcode.DrawBarcode(reImage, 0, 0);// draw barcode on REImage with location x and y

reImage.Save(ImageType.PNG, @"c:/barcode.png");
