eclipse Image創建方法

    private Image createImage() {
		Image image = null;
		ImageDescriptor imageDescriptor = Activator.getImageDescriptor(imagePath);
		if(imageDescriptor != null) {
			image = imageDescriptor.createImage();
		}
		else {
			System.out.print("Image path error!");
		}
		return image;
	}

imagePath爲String類型image的相對路徑，格式爲"icons/sample.png"，不可以設爲"./icons/sample.png"或"/icons/sample.png"。

其中class Activator定義如下：

/**
 * The activator class controls the plug-in life cycle
 */
public class Activator extends AbstractUIPlugin {

	// The plug-in ID
	public static final String PLUGIN_ID = "com.license.ui"; //$NON-NLS-1$

	// The shared instance
	private static Activator plugin;
	
	/**
	 * The constructor
	 */
	public Activator() {
		plugin = this;
	}

	@Override
	public void start(BundleContext context) throws Exception {
		super.start(context);
		plugin = this;
	}

	@Override
	public void stop(BundleContext context) throws Exception {
		plugin = null;
		super.stop(context);
	}

	/**
	 * Returns the shared instance
	 *
	 * @return the shared instance
	 */
	public static Activator getDefault() {
		return plugin;
	}

	/**
	 * Returns an image descriptor for the image file at the given
	 * plug-in relative path
	 *
	 * @param path the path
	 * @return the image descriptor
	 */
	public static ImageDescriptor getImageDescriptor(String path) {
		return imageDescriptorFromPlugin(PLUGIN_ID, path);
	}
}
