| ImagePane | | public class ImagePane extends ZoomPane implements Runnable(Code) | | A simple image viewer. This widget accepts either
or
image. Rendered image are display immediately,
while renderable image will be rendered in a background thread when first requested.
This widget may scale down images for faster rendering. This is convenient for image
previews, but should not be used as a "real" renderer for full precision images.

| Constructor Summary | |
| public | ImagePane()
Constructs an initially empty image pane with a default rendered image size. | | public | ImagePane(int renderedSize)
Constructs an initially empty image pane with the specified rendered image size.
The
renderedSize argument is the maximum width and height for
. |
| Method Summary | |
| public Rectangle2D | getArea()
Returns the image bounds, or
null if none. | | protected void | paintComponent(Graphics2D graphics)
Paint the image. | | public void | reset()
Reset the default zoom. | | public void | run()
Creates a
view of the
image and notifies
ZoomPane when the result is ready. | | public void | setImage(RenderableImage image)
Sets the source renderable image. | | public void | setImage(RenderedImage image)
Sets the source rendered image. |
| ImagePane | | public ImagePane()(Code) | | Constructs an initially empty image pane with a default rendered image size.
|
| ImagePane | | public ImagePane(int renderedSize)(Code) | | Constructs an initially empty image pane with the specified rendered image size.
The
renderedSize argument is the maximum width and height for
. Images greater than this value will be
scaled down for faster rendering.
|
| getArea | | public Rectangle2D getArea()(Code) | | Returns the image bounds, or
null if none. This is used by
ZoomPane in order to set the initial zoom.
|
| paintComponent | | protected void paintComponent(Graphics2D graphics)(Code) | | Paint the image. If the image was a
RenderableImage , then a
RenderedImage will be computed in a background thread when this method is first invoked.
|
| reset | | public void reset()(Code) | | Reset the default zoom. This method overrides the default implementation in
order to keep the y axis in its Java2D direction (y
value increasing down), which is the usual direction of most image.
|
| run | | public void run()(Code) | | Creates a
view of the
image and notifies
ZoomPane when the result is ready. This method
is run in a background thread and should not be invoked directly, unless the user wants
to trig the
RenderedImage creation immediately.
|
| setImage | | public void setImage(RenderableImage image)(Code) | | Sets the source renderable image.
|
| setImage | | public void setImage(RenderedImage image)(Code) | | Sets the source rendered image.
