## com.nwoods.jgo.web
Class JGoJPEGView

    java.lang.Object
      java.awt.Component
          java.awt.Container
              javax.swing.JComponent
                  com.nwoods.jgo.JGoView
                      com.nwoods.jgo.web.JGoJPEGView

All Implemented Interfaces:
  java.awt.dnd.Autoscroll, java.awt.datatransfer.ClipboardOwner, java.awt.dnd.DragGestureListener, java.awt.dnd.DragSourceListener, java.awt.dnd.DropTargetListener, java.util.EventListener, java.awt.image.ImageObserver, JGoDocumentListener, JGoObjectCollection, JGoObjectSimpleCollection, java.awt.event.KeyListener, java.awt.MenuContainer, java.awt.print.Printable, java.io.Serializable

public class JGoJPEGView
extends JGoView

This class is used to generate JPEG images of JGoDocuments

If you use this in an environment where the app has no visible window, make sure you call JGoGlobal.setup() first so that there is a window available to JGoText for measuring text.

Constructor Summary
`JGoJPEGView(JGoDocument doc)`

Method Summary
`java.awt.Dimension` | `getViewSize()` The ViewSize property is maintained separately by this class because we cannot depend on the Canvas actually being realized, and because we want it to be independent of the Canvas.
`void` | `render(java.io.OutputStream outs)` Produce a JPEG file on the given OutputStream, showing a rendering of this view's document at a document location determined by getViewPosition() at a scale determined by getScale() and of an image size given by getViewSize() pixels.
`void` | `setViewSize(java.awt.Dimension d)`
