public class HTMLImage
extends WebContent

Attribute for inserting an image into a web page. Drag this attribute onto an actor that produces a BasicGraphFrame (for example, ptolemy.actor.lib.gui.XYPlotter) and specify the caption for this image. By default, this image will be placed at the end of the HTML page, but you can change the position by setting the imagePosition parameter. You can also separately control what text is displayed in the model, or make the attribute disappear altogether in the model (for this, just set displayText to an empty string). Based on ptolemy.vergil.basic.export.web.HTMLText
