Deploy RasterEdge Imaging
Because RasterEgde Imaging toolkit is a collection of assemblies, you need to add reference to
specific assemblies in your project to use the APIs provided.
To add reference to RasterEdge Imaging assemblies in your project using Visual Studio:
a.
In the Solution Explorer, right-click on References, and click Add Reference.
You download
from our server.
b. Click the browse menu tab to locate RasterEdge.DocImageSDK8.x\Bin
c. Choose dlls that you want to use in your project.
d. Add using statement at the top of the code, for example

Online Demo
Using RasterEdge document sdk, you can build a project to enable document viewing,
annotating, converting, and saving. We develop an online document viewer program to
illustrate these features.
You can not only try using our demo documents but upload your own documents as well.
