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.

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.

Method Detail

render

public 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.

getViewSize

public 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.

setViewSize

public void setViewSize(java.awt.Dimension d)
