VB Imaging - VB Leitcode Generator SDK Library

VB Imaging - Leitcode Barcoding Add-On Overview

The VB.NET barcode creator add-on from RasterEdge .NET Imaging SDK is a professional and mature .NET solution that is used to help developers integrate fast & accurate 1d (like Leitcode) & 2d barcode generating functions into their VB.NET projects. As this VB.NET barcode generator library add-on owns both barcode generating and image processing functions, it has often been used for automating image capturing and management system in a programming way. c# print pdf creator, itextsharp remove text from pdf c#, vb.net pdf merge and compress, convert pdf to html c#, convert powerpoint to pdf c# interop, extract text from pdf c#, c# remove images from pdf.

This online VB.NET tutorial is mainly designed to tell developers how to create & add Leitcode barcode on source image or document file in VB.NET developing application. From this VB.NET Leitcode barcode generating tutorial page, you will find both theoretical guidance and VB.NET code demos for Leitcode barcode drawing and generation on raster image formats and multi-page document files. asp.net c# view pdf, how to add header and footer in pdf using itextsharp in asp.net, mvc view to pdf itextsharp, asp.net mvc pdf editor, asp.net mvc open word document in browser, pdf preview in asp net c# example, asp net add text to pdf.

Before guiding you how to create Leitcode barcode on source document image file in VB.NET, we think it may be necessary to briefly introduce this linear Leitcode barcode symbology. To create a valid and highly-readable Leitcode barcode using RasterEdge VB.NET barcode creator add-on, there are four points that you may need to keep in mind.

Point 1: Leitcode barcode is a numeric barcode type, which means you can only encode digit data (0-9) into this barcode symbology.

Point 2: Leitcode barcode is a 1d barcode with fixed data length, which means that you can only input 13-digit data in this barcode, excluding the check digit.

Point 3: The check digit of Leitcode barcode will be automatically computed and added based on your encoded data, which means you do not need to worry about the checksum character issue.

Point 4: The minimum margin of Leitcode barcode is 10X (x refers to the bar width). And by default, this VB.NET barcode creator will create a Leitcode barcode with 10X-width margins.
