Rogue Wave JViews Framework Sample: Reading an SVG File

Description

This simple sample shows how to use the IlvMagnifyInteractor class to magnify an area of a Rogue Wave JViews IlvManager instance that has been filled with contents imported from a file in Scalable Vector Graphic (SVG) format.

How to Use the Sample

• To show the magnifier, click a mouse button in the view.
• Change the size of the magnified area using the '+' and '-' keys.
• Change the magnification factor using the '>' and '<' keys.
• Press the Alt key to go into LENS mode. Release the Alt key to return to CIRCULAR mode.
• Scale the map using the Ctrl+Z and Ctrl+U keys.
• Pan the map using the arrow keys.
• Press the 'f' key to fit the map to the size of the application.

How to Run the Sample as an Application

This sample can be run as an application. The installation directory contains an executable JAR file, reading-svg.jar, that allows you to execute the sample with a double click from a file browser. Note that if you are using Internet Explorer, you can open the installation directory and execute the JAR file from the browser. This technique may not work in other Web browsers.

Alternatively, you can run the sample application from the command line. First check that the Ant utility is properly configured. If not, see the instructions on how to configure Ant for Rogue Wave JViews.

Then, go to the installation directory of the sample and type:

ant run
