The Service Settings dialog allows you to define three configuration options for the ASP.NET application. These settings define parameters that control how the ASP.NET components are initialized: 

Bin Directory: Defines the location of the ImageGear for .NET Assemblies. This path can be defined as a relative path, based on the location of the web.config file, by using a tilde, "~".

PDF Directory: Defines the location of the ImageGear for .NET PDF binaries. More information on distributing the PDF Libraries can be found in the Distributing PDF and PS Fonts and Libraries section of the documentation. This path can be defined as a relative path, based on the location of the web.config file, by using a tilde, "~".

Max Threads Per Control: Specifies the maximum number of threads that should be created to process ASP.NET requests.
