This white paper describes how you can use the ImageDraw's Dynamic Image Composition concept when working with real world XML Web Services such us Amazon Web Services which provides developers with direct access to Amazon's robust technology platform.
In order to demonstrate how you can use ImageDraw's Dynamic Image Composition concept in Web Services scenarios, a fictitious ASP.NET Music Search page was developed. The idea behind that demo application is to leverage search power and content data to Amazon Web Services while leveraging visual appearance of search results to ImageDraw controls. The following figure shows how the demo application works.
This sample demo was developed using Neodynamic ImageDraw controls, ASP.NET 2.0, and Visual Studio 2005. If you're using Visual Web Developer Express Edition you can open and run the download files as well.
Key features of this sample demo

Use Amazon Web Service (AWS) to get music titles based on keywords entered by users. The address of the WSDL (Web Services Description Language) file for the Amazon Web Services is this: http://webservices.amazon.com/AWSECommerceService/AWSECommerceService.wsdl |
IMPORTANTAmazon Web Services require a subscription ID that you must pass with all requests to the service. In order to run the demo application on your machine you must ensure to register and receive your subscription ID at http://www.amazon.com/gp/aws/registration/registration-form.html
- An ImageDraw control - inside a DataList - is used to dynamically merge local "static" images - a CD Case and a Price Spot - with CD Music Cover images and prices returned by Amazon Web Services, highly improving the whole appearance of the search results page. All this content is rendered by ASP.NET Data Binding.
