Viewing Multiple ECW Layers tutorial
Overview
This tutorial shows you how to view multiple ECW images from an Image Web Server using the native ECW plug-in and then connect the view to a Toolbar and Progress bar using JavaScript. A transparency slider is implemented to blend the top ECW image with the one underneath. Select the Pointer tool and click on the map to display the coordinates in Latitude/Longitude. Click on the image name to promote the image to the top of the View stack.
