VB Imaging - Micro QR Code Generation Guide

VB Imaging - VB Micro QR Code Barcode Generator Overview

Micro QR Code Generator for VB is simply one barcode writing functionality of RasterEdge .NET imaging toolkit. With this component DLL, users can develop VB.NET applications to create, print Micro QR Code 2D bar codes in images such as png, jpeg/jpg, gif and bmp. asp.net edit pdf, asp.net pdf preview, asp net mvc generate pdf from view itextsharp, asp.net display tiff images, asp net show word document in browser, how to show pdf file in asp.net page c#, how to add header and footer in pdf using itextsharp in asp.net. Besides these image formats, PDF, TIFF, Word, Excel and PowerPoint documents are also supported for barcode generation. Developers can easily resize barcode image, change colors, and customize resolution & orientation using Visual VB.NET coding. vb.net pdfsharp convert pdf to image, convert csv to pdf c#, c# code to compress pdf, c# create pdf preview, vb.net itextsharp split pdf, c# pdf number of pages, add watermark to pdf vb.net.

Please copy the sample code as follow to generator a Micro QR Code barcode.

Dim  barcode As MicroQRCode = New MicroQRCode ()
'create a Data Matrix barcode
'encode data into Data Matrix barcode
barcode.Data = "123456789"
'set module size
barcode.X = 5.0F
'the minimum value for each margin should be equal to X
barcode.RightMargin = barcode.LeftMargin = barcode.TopMargin = barcode.BottomMargin = barcode.X
'set barcode printing resolution
barcode.Resolution = 96
'set rotation
barcode.Rotate = Rotate.Rotate0
barcode.BarcodeHeight = 200
barcode.BarcodeWidth = 200
barcode.AutoResize = true

'convert barcode to a bitmap and save it to image file
'Dim bmp As Bitmap = barcode.ToImage()
'bmp.Save(@"C:\barcode.bmp")

VB Imaging - Draw Micro QR Code on Image File

If you want to add Micro QR Code barcode generating features to your VB.NET image processing application, try this .NET Barcode Creator Add-on, which supports common raster image file formats: png, gif, jpeg, and bmp. Copy the sample code below to your VB imaging program and you can create a Micro QR Code on the bottom left corner of a sample png image.

You can change the location by setting X and Y coordinates in Visual VB.NET sample codes. For more Micro QR Code parameters, please refer to the table demonstrated below.

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

VB Imaging - Create Micro QR Code on Document Page

Besides .NET imaging applications, developers can also apply this barcode DLL to VB.NET document manipulating project. Currently we support document types like PDF, TIFF, Microsoft Word, Excel and PPTX, both single page file and multi-page ones. Displayed below are VB examples for drawing Micro QR Code to supported documents.
