EXAMPLE TITLE	LINKS	EXAMPLE FEATURES
Hello World Basic 1 - ECWP Using Embedded Objects (Deprecated)	tutorial page	This page uses embedded objects for creating the View, Toolbar and Progress Bar controls. It uses the attach method to link the objects. This is the older (and now deprecated) method of using the controls. It has been included here as a transitional page for developers who are familiar with this approach and are starting to work with the new methods available in the Layered View control. The same functionality is implemented in the next tutorial with the use of supplied classes. That is now the recommended coding approach.
Hello World Basic 2 - ECWP Using Supplied Classes (recommended)	tutorial page	This tutorial uses the supplied classes for creating the View, Toolbar and Progress Bar controls, and attaches them in JavaScript code. This is the strongly recommended coding approach because it works in both Internet Explorer 5.5 and Netscape 7+ (Mozilla style) browsers, as well as with the Java Applet. Learning and using these classes makes coding simpler and more reliable since each release of Image Web Server automatically supplies new JavaScript Include files. These files update the classes, taking care of new browser versions.
ArcXML Overlay Example -Overlay ESRI ArcXML image in Layered View Control	tutorial page	The ArcXML overlay tutorial shows you how to add an ESRI ArcXML Overlay layer on top of an ECWP image layer in the Layered View Control. The ArcXML layer can be selected from either your local Image Web Server ArcXML service, or from the public ESRI ArcIMS Server that is part of the Geography Network. The page demonstrates how, as the extents of the map view are changed, a new request to the ArcXML service is triggered which is then processed to extract an image URL for the updated map PNG image. This is then substituted into the layer using the parameters of the control.
Basic OGC WMS Viewer - A basic viewer for the OGC WMS Protocol	tutorial page	This page is an example of a basic WMS viewer for viewing ECW Images. It shows you how to build a web page that does not need the ECW plug-in for viewing JPEGs extracted from ECW images by the OGC WMS Service of your Image Web Server. This service makes use of the ecw_wms.dll ISAPI extension. Note: You will need the OGC WMS Service active on your Image Web Server for this exercise to work.
Basic ImageX Viewer - A basic viewer for the ImageX Protocol.	tutorial page	This page is an example of a basic ImageX Viewer. It demonstrates building a web page without the need for the ECW Plug-in for viewing JPEGs extracted from ECW Images by the ImageX Service (using the ImageX.dll ISAPI extension) of your Image Web Server.
Step-by-Step Tutorial - Build a Web Page from scratch with step-by-step instructions.	start page tutorial final page	This tutorial provides step-by-step instructions on how to build your own web page starting from a basic template page. You will add View, ToolBar and ProgressBar controls and add JavaScript functions to attach them together. A slider will be integrated to blend the two ECW images in the View. Callbacks will be added to display the map extents and the Latitude/Longitude readings as you move the mouse pointer over the map. As this is a detailed exercise, it is provided as a PDF document which you may want to print for reference as you proceed through the tutorial.
Multiple Layer - Advanced - An Advanced Example with multiple ECW layers.	tutorial page	This page demonstrates loading up to four ECW images from the demo.ermapper.com Image Web Server into the Layered View control. Images can be turned on or off, promoted to the top in the viewing stack, and the transparency adjusted on the topmost image layer. A roam window can be set on the topmost layer which follows the mouse around. Callbacks are used to display the current map extents and display the Latitude and Longitude based on the position of the mouse cursor.
