Remarks
To specify a custom Integration Provider, override PdfIntegrationProvider and the desired members, then register it in the appropriate web.config file. If a custom Integration Provider is not registered in a web application's web.config file, DefaultPdfIntegrationProvider is used.
Examples
The following example overrides the default PdfIntegrationProvider to create a custom Integration Provider for the web application.
C#
using System;
using System.Web;

using RadPdf.Data.Document.Objects.Shapes;
using RadPdf.Integration;

public class CustomPdfIntegrationProvider : PdfIntegrationProvider
{
    public override void OnObjectDataAdding(ObjectDataAddingEventArgs e)
    {
        base.OnObjectDataAdding(e);

        //if data is added to an image
        if (e.PdfObjectType == typeof(PdfImageShape))
        {
            //check image size (if larger than 1 MB)
            if (e.Data.Length > 0x100000)
            {
                e.Cancel = true;
                e.CancelMessage = "Maximum image size is 1 MB.";
            }
        }
        else
        {
            throw new ArgumentException("PdfObjectType unsupported.");
        }
    }
}
The following web.config file registers the above custom Integration Provider. This example assumes that CustomPdfIntegrationProvider is in the directory App_Code of your ASP.NET web application.
