VB Imaging - VB ISBN Barcode Tutorial

Overview on VB ISBN Barcode Creating

This VB.NET ISBN barcode creator control add-on is often used in two main .NET imaging applications. One is for common image & picture processing application, which allows VB.NET developers to draw ISBN barcode on common image file formats, like png, jpeg, gif, bmp and tiff. The other is for daily document managing system, which allows VB.NET developers to add ISBN barcode image to document files, like PDF and Word documents.

Before guiding you to create standard ISBN barcode on source image or document file, we will first briefly introduce the linear barcode symbology itself. ISBN, short for International Standard Book Number, can only encode digit characters 0-9. Besides, according to the international specifications, a valid ISBN barcode should start with "978" or "979" only and consist of 13 digits, including the check digit that will be automatically computed and added by this VB.NET ISBN barcode creator add-on.

RasterEdge DocImage Barcode Add-On SDK for .NET contains several DLLs / libraries to meet multiple image processing and manipulation needs, among which barcode reading and writing abilities are included. The RasterEdge.Imaging.Barcode.Creator.dll allows VB developers to easily generate ISBN linear barcode on images (supported image formats: GIF, BMP, PNG & JPEG) and documents (supported documents: PDF, TIFF, Excel, PowerPoint & Word).

Detailed features are listed below:

Easy to use .NET solution that is designed to create ISBN barcode on image or document file using VB.NET code

Automatically compute and add check digit for ISBN barcode in VB.NET imaging application

Support generating transparent ISBN barcode image on document files in VB.NET like PDF & Word

Free to add high-quality ISBN barcode to common raster image formats using VB.NET code

Created ISBN barcode can be easily resized, repositioned and reoriented on source document image file in VB.NET

Support other linear and 2d barcodes on document image file, like Code 39, UPC-A and PDF 417

Created ISBN barcode can be accurately decoded by .NET barcode reader or other barcode scanners

VB Code for Customizing ISBN Barcode Generation

You can easily generator ISBN barcode and save it  to image files/object using this VB.NET barcode generator control. The following steps will show how to create a ISBN type barcode encoding numeric data text "978047082163" into the image object with XImage.Barcode.Creator.

Dim barcode As Linear = New Linear()
'select barcode type
barcode.Type = BarcodeType.ISBN
'set barcode data
barcode.Data = "978047082163"

'bmp.Save(@"C:\barcode.bmp")

Create ISBN Barcode on VB Program Image

RasterEdge barcode generator add-on control library supports creating / writing ISBN (International Standard Book Number) in VB project & program. Displayed below is the Visual VB demo code to create an ISBN encoding "978047082163" on a sample png image, and save it to your local disk C. You can also change the sample image to a jpeg, gif or bmp image.

Dim image As REImage  = New REImage("C:\\Sample.png")
barcode.DrawBarcode(image, 150F, 150F)
image.Save(ImageType.PNG, "C:\\Sample_Barcode.png")

Generate ISBN on VB Document Page

Besides the image formats listed above, RasterEdge .NET barcode generator component can also create and print ISBN on these files: PDF, TIFF, Microsoft Office Word / docx document, Excel and PowerPoint. Five samples are provided below for ISBN barcode writing on each of these five documents.

Some simple barcode settings are offered in the codings and you can also make more adjustments with the properties from the table in the following section. Besides, VB.NET users can freely control the specific location of ISBN barcode on sample image by setting x and y coordinates using VB.NET programming language.
