Method Summary | |
---|---|
void |
drawImageGraphics(BasicImageDisplay imageDisplay,
java.awt.Graphics2D g)
Called each time the image is repainted to draw a rectangle on the image marking the position of the mouse pointer in the target image. |
BasicImageDisplay |
getImageDisplay()
Return the zoom image display. |
MainImageDisplay |
getMainImageDisplay()
Return the target ImageDisplay that we are monitoring. |
float |
getZoomFactor()
Return the zoom factor |
boolean |
isActive()
Return the active state of the zoom window |
boolean |
isEnabled()
Return the enabled state of the zoom window |
boolean |
isPropagateScale()
Return true if changes in the main image scale are propagated to the zoom window. |
void |
setActive(boolean b)
Set the active state to false to stop the zoom window from updating when the mouse is moved over the main image. |
void |
setEnabled(boolean b)
Enable or disable the zoom window |
void |
setMainImageDisplay(MainImageDisplay mainImageDisplay)
Set the target image display that we are monitoring. |
void |
setPropagateScale(boolean b)
If true (default), changes in the main image scale are propagated to the zoom window. |
void |
setZoomFactor(float factor)
Set the zoom factor |
void |
stateChanged(javax.swing.event.ChangeEvent ce)
Called when the main image changes in some way. |
void |
updateRect()
Update the rect object with the coordinates of the mouse pointer in the target image. |
void |
zoom(int x,
int y,
boolean force)
This method is called when the mouse is moved over the target image. |
