```
public class DebugGraphics
extends Graphics
```
Graphics subclass supporting graphics debugging. Overrides most methods from Graphics. DebugGraphics objects are rarely created by hand. They are most frequently created automatically when a JComponent's debugGraphicsOptions are changed using the setDebugGraphicsOptions() method.
NOTE: You must turn off double buffering to use DebugGraphics: RepaintManager repaintManager = RepaintManager.currentManager(component); repaintManager.setDoubleBufferingEnabled(false);
Since:
1.2
See Also:
JComponent.setDebugGraphicsOptions(int), RepaintManager.currentManager(java.awt.Component), RepaintManager.setDoubleBufferingEnabled(boolean)

  - setDebugOptions
```
public void setDebugOptions(int options)
```
    Enables/disables diagnostic information about every graphics operation. The value of options indicates how this information should be displayed. LOG_OPTION causes a text message to be printed. FLASH_OPTION causes the drawing to flash several times. BUFFERED_OPTION creates a new Frame that shows each operation on an offscreen buffer. The value of options is bitwise OR'd into the current value. To disable debugging use NONE_OPTION.
    Parameters:
    options - indicates how diagnostic information should be displayed
  - getDebugOptions
```
public int getDebugOptions()
```
    Returns the current debugging options for this DebugGraphics.
    Returns:
