To get started with DocImage SDK for .NET, you are supposed to read VB.NET Imaging: Get Started first!

DocImage SDK for .NET, VB.NET is a mature suite with many easy to use .NET assemblies to be integrated into your imaging applications so that VB.NET developers are enabled to load an image or bulk ones from .NET Graphics for processing and editing, such as barcode writing & reading, image displaying & viewing, resizing and annotating, as well as image converting and printing. These image loading & processing functions can be easily integrated into various VB.NET projects such as Class Library, Windows application and ASP.NET web application.

With this image processing library toolkit for VB.NET installed into your computer, Visual Basic .NET users can easily load & open an image from .NET Graphics bitmap, as well as from .NET Graphics screen. Currently, most common image formats such as png, jpeg, gif, tiff and bmp are supported by this professional VB.NET imaging library.
This page is a step by step guide which provides you with details on how to load an image from .NET Graphics. Examples and VB.NET sample codes will be given in the following sections:
  • Examples to load an image from .NET Graphics bitmap using VB.NET codes
  • Samples to import an image from .NET Graphics screen with VB.NET programming
  • More image processing & editing functionality and guides
Load VB.NET Image from .NET Graphics
This is a detailed VB.NET sample for loading image from .NET Graphics with RasterEdge .NET Imaging SDK. (For C#.NET developers, we provide How to Load Image from .NET Graphics in C#.) To get it started, you can either create a Windows application or an ASP.NET web application for your image editing program, then you can follow the guide below for image loading.
In addition, before integrating this VB.NET imaging assemblies into your program, you need to meet the following two requirements. The first one is for you to install Microsoft .NET Framework 2.0 or above versions. The second requirement is to install the MS Visual Studio, supporting from VS 2005 to 2012 versions.
At present we provide two VB.NET methods for you to load an image from .NET Graphics: loading from .NET Graphic bitmap and loading from .NET Graphic screen. In the following sections, VB.NET demo codes are provided for both methods. Please go to corresponding section for more information.

VB Guide: Load Image from Graphic Bitmap Method

Here is the Visual Basic .NET method for loading an image from .NET Graphic bitmap.
