public void showPage(PDFPage page)

Stop the generation of any previous page, and draw the new one.

Parameters:

page - the PDFPage to draw.

flush

public void flush()

Deprecated.

paint

public void paint(java.awt.Graphics g)

Draw the image.

Overrides:

paint in class javax.swing.JComponent

getPage

public PDFPage getPage()

Gets the page currently being displayed

getCurSize

public java.awt.Dimension getCurSize()

Gets the size of the image currently being displayed

getCurClip

public java.awt.geom.Rectangle2D getCurClip()

Gets the clipping rectangle in page space currently being displayed

waitForCurrentPage

public void waitForCurrentPage()

Waits until the page is either complete or had an error.

imageUpdate

public boolean imageUpdate(java.awt.Image img,
                           int infoflags,
                           int x,
                           int y,

                           int height)

Handles notification of the fact that some part of the image changed. Repaints that portion.

Specified by:

imageUpdate in interface java.awt.image.ImageObserver

Overrides:

imageUpdate in class java.awt.Component

Returns:

true if more updates are desired.

useZoomTool

public void useZoomTool(boolean use)

Turns the zoom tool on or off. If on, mouse drags will draw the zooming marquee. If off, mouse drags are ignored.

setClip

public void setClip(java.awt.geom.Rectangle2D clip)

Set the desired clipping region (in screen coordinates), and redraw the image.

mousePressed

public void mousePressed(java.awt.event.MouseEvent evt)

Handles a mousePressed event

Specified by:

mousePressed in interface java.awt.event.MouseListener

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent evt)

Handles a mouseReleased event. If zooming is turned on and there's a valid zoom rectangle, set the image clip to the zoom rect.

Specified by:

mouseReleased in interface java.awt.event.MouseListener

mouseClicked
