Method Details

copyAreaImpl

public void copyAreaImpl(int x,
                         int y,
                         int width,
                         int height,
                         int dx,
                         int dy)
Overrides:
copyAreaImpl in interface ComponentGraphics

create

public Graphics create()
These are declared abstract as there may be context-specific issues.
Overrides:
create in interface ComponentGraphics

drawImage

public boolean drawImage(Image img,
                         int x,
                         int y,
                         int width,
                         int height,
                         ImageObserver observer)
Draws all of the image that is available and returns. The image is scaled to fit in the specified rectangle. If the image is not completely loaded, false is returned and the specified iamge observer is notified as more data becomes available.
Overrides:
drawImage in interface ComponentGraphics
Parameters:
x - The X coordinate of the point to draw at.
y - The Y coordinate of the point to draw at.
width - The width of the rectangle to draw in.
height - The height of the rectangle to draw in.
observer - The image observer to notify as data becomes available.
Returns:
true if all the image data is available, false otherwise.

drawImage

public boolean drawImage(Image img,
                         int x,
                         int y,
                         ImageObserver observer)
Draws all of the image that is available and returns. If the image is not completely loaded, false is returned and the specified iamge observer is notified as more data becomes available.
Overrides:
drawImage in interface ComponentGraphics
Parameters:
x - The X coordinate of the point to draw at.
y - The Y coordinate of the point to draw at.
observer - The image observer to notify as data becomes available.
Returns:
true if all the image data is available, false otherwise.

getDeviceConfiguration

public GraphicsConfiguration getDeviceConfiguration()
Overrides:
getDeviceConfiguration in interface ComponentGraphics

getRealBounds

protected Rectangle2D getRealBounds()
Overrides:
getRealBounds in interface ComponentGraphics
