The LEADTOOLS WebImageViewer supports a group of image processing commands that can be applied to the loaded image through the Leadtools.Web.Controls.WebImageViewer.ApplyCommand(Leadtools.ImageProcessing.RasterCommand) method.
The following table contains the server/client commands that are currently supported by the WebImageViewer control, and how to get/set the client command class properties on the client side.

To apply one of the above commands to the image from client-side do something like the following:
// this code rotates the image of WebImageViewer1 by 45 degrees.
function RotateImage()
{
var cmd = new RotateCommand(4500, RotateCommandFlags.Bicubic, '#FF00FF');
WebImageViewer1.WebImageViewer.ApplyCommand(cmd);
}
