public class Image
extends Widget
implements SourcesLoadEvents, HasLoadHandlers, HasErrorHandlers, SourcesClickEvents, HasClickHandlers, HasDoubleClickHandlers, HasAllDragAndDropHandlers, HasAllGestureHandlers, HasAllMouseHandlers, HasAllTouchHandlers, SourcesMouseEvents
```
A widget that displays the image at a given URL. The image can be in 'unclipped' mode (the default) or 'clipped' mode. In clipped mode, a viewport is overlaid on top of the image so that a subset of the image will be displayed. In unclipped mode, there is no viewport - the entire image will be visible. Whether an image is in clipped or unclipped mode depends on how the image is constructed, and how it is transformed after construction. Methods will operate differently depending on the mode that the image is in. These differences are detailed in the documentation for each method.
If an image transitions between clipped mode and unclipped mode, any Element-specific attributes added by the user (including style attributes, style names, and style modifiers), except for event listeners, will be lost.

CSS Style Rules

.gwt-Image
The outer element
Tranformations between clipped and unclipped state will result in a loss of any style names that were set/added; the only style names that are preserved are those that are mentioned in the static CSS style rules. Due to browser-specific HTML constructions needed to achieve the clipping effect, certain CSS attributes, such as padding and background, may not work as expected when an image is in clipped mode. These limitations can usually be easily worked around by encapsulating the image in a container widget that can itself be styled.

Example
```
public class ImageExample implements EntryPoint {

  private Label lbl = new Label();
  private Button btn = new Button("Clip this image");
  private Button btn2 = new Button("Restore image");

  public void onModuleLoad() {
    // Create an image, not yet referencing a URL. We make it final so that we
    // can manipulate the image object within the ClickHandlers for the buttons.
    final Image image = new Image();

    // Hook up an error handler, so that we can be informed if the image fails
    // to load.
    image.addErrorHandler(new ErrorHandler() {
      public void onError(ErrorEvent event) {
        lbl.setText("An error occurred while loading.");
      }
    });

    // Point the image at a real URL.
    image.setUrl("http://www.google.com/images/logo.gif");

    // When the user clicks this button, we want to clip the image.
    btn.addClickHandler(new ClickHandler() {
      public void onClick(ClickEvent event) {
        image.setVisibleRect(70, 0, 47, 110);
      }
    });
    btn.setWidth("120px");

    // When the user clicks this button, we want to restore the image to its
    // unclipped state.
    btn2.addClickHandler(new ClickHandler() {
      public void onClick(ClickEvent event) {
        image.setUrl("http://www.google.com/images/logo.gif");
      }
    });
    btn2.setWidth("120px");

    // Add the image, label, and clip/restore buttons to the root panel.
    VerticalPanel panel = new VerticalPanel();
    panel.add(lbl);
    panel.add(image);

    HorizontalPanel buttonPanel = new HorizontalPanel();
    buttonPanel.add(btn);
    buttonPanel.add(btn2);

    panel.add(buttonPanel);

    RootPanel.get().add(panel);

```
public Image()
```
    Creates an empty image.
  - Image
```
public Image(ImageResource resource)
```
    Creates an image whose size and content are defined by an ImageResource.
    
    Parameters:
    
    resource - the ImageResource to be displayed
  - Image
```
public Image(java.lang.String url)
```
    Creates an image with a specified URL. The load event will be fired once the image at the given URL has been retrieved by the browser.
    
    Parameters:
    
    url - the URL of the image to be displayed
  - Image
```
public Image(SafeUri url)
```
    Creates an image with a specified URL. The load event will be fired once the image at the given URL has been retrieved by the browser.
    
    Parameters:
    
    url - the URL of the image to be displayed

             int height)
```
    Creates a clipped image with a specified URL and visibility rectangle. The visibility rectangle is declared relative to the rectangle which encompasses the entire image, which has an upper-left vertex of (0,0). The load event will be fired immediately after the object has been constructed (i.e. potentially before the image has been loaded in the browser). Since the width and height are specified explicitly by the user, this behavior will not cause problems with retrieving the width and height of a clipped image in a load event handler.
    
    Parameters:
    
    url - the URL of the image to be displayed
    
    left - the horizontal co-ordinate of the upper-left vertex of the visibility rectangle

    Parameters:
    
    altText - the alternate text to set to
  - setResource
```
public void setResource(ImageResource resource)
```
    Sets the url and the visibility rectangle for the image at the same time, based on an ImageResource instance. A single load event will be fired if either the incoming url or visiblity rectangle co-ordinates differ from the image's current url or current visibility rectangle co-ordinates. If the image is currently in the unclipped state, a call to this method will cause a transition to the clipped state.
    
    Parameters:
    
    resource - the ImageResource to display
  - setUrl
```
public void setUrl(SafeUri url)
```
    Sets the URL of the image to be displayed. If the image is in the clipped state, a call to this method will cause a transition of the image to the unclipped state. Regardless of whether or not the image is in the clipped or unclipped state, a load event will be fired.
    
    Parameters:
    
    url - the image URL
  - setUrl
```
public void setUrl(java.lang.String url)
```
    Sets the URL of the image to be displayed. If the image is in the clipped state, a call to this method will cause a transition of the image to the unclipped state. Regardless of whether or not the image is in the clipped or unclipped state, a load event will be fired.
    
    Parameters:
    
    url - the image URL
  - setUrlAndVisibleRect
```
public void setUrlAndVisibleRect(SafeUri url,
                                 int left,
                                 int top,

                                 int height)
```
    Sets the url and the visibility rectangle for the image at the same time. A single load event will be fired if either the incoming url or visiblity rectangle co-ordinates differ from the image's current url or current visibility rectangle co-ordinates. If the image is currently in the unclipped state, a call to this method will cause a transition to the clipped state.
    
    Parameters:
    
    url - the image URL
    
    left - the horizontal coordinate of the upper-left vertex of the visibility rectangle
    
    top - the vertical coordinate of the upper-left vertex of the visibility rectangle
    
    width - the width of the visibility rectangle
    
    height - the height of the visibility rectangle
  - setUrlAndVisibleRect
```
public void setUrlAndVisibleRect(java.lang.String url,
                                 int left,

                                 int width,
                                 int height)
```
    Sets the url and the visibility rectangle for the image at the same time. A single load event will be fired if either the incoming url or visiblity rectangle co-ordinates differ from the image's current url or current visibility rectangle co-ordinates. If the image is currently in the unclipped state, a call to this method will cause a transition to the clipped state.
    
    Parameters:
    
    url - the image URL
    
    left - the horizontal coordinate of the upper-left vertex of the visibility rectangle
    
    top - the vertical coordinate of the upper-left vertex of the visibility rectangle
    
    width - the width of the visibility rectangle
    
    height - the height of the visibility rectangle
  - setVisibleRect
```
public void setVisibleRect(int left,
                           int top,
                           int width,
                           int height)
```
    Sets the visibility rectangle of an image. The visibility rectangle is declared relative to the rectangle which encompasses the entire image, which has an upper-left vertex of (0,0). Provided that any of the left, top, width, and height parameters are different than the those values that are currently set for the image, a load event will be fired. If the image is in the unclipped state, a call to this method will cause a transition of the image to the clipped state. This transition will cause a load event to fire.
    
    Parameters:
    
    left - the horizontal coordinate of the upper-left vertex of the visibility rectangle
    
    top - the vertical coordinate of the upper-left vertex of the visibility rectangle
    
    width - the width of the visibility rectangle
    
    height - the height of the visibility rectangle
