Method Details

createCompatibleImage

public BufferedImage createCompatibleImage(int width,
                                           int height)
Returns a buffered image optimized to this device, so that blitting can be supported in the buffered image.
Overrides:
createCompatibleImage in interface GraphicsConfiguration
Parameters:
Returns:
the buffered image, or null if none is supported

createCompatibleImage

public BufferedImage createCompatibleImage(int width,
                                           int height,
                                           int transparency)
Returns a buffered image optimized to this device, so that blitting can be supported in the buffered image.
Overrides:
createCompatibleImage in interface GraphicsConfiguration
Parameters:
Returns:
the buffered image, or null if none is supported

createCompatibleVolatileImage

public VolatileImage createCompatibleVolatileImage(int w,
                                                   int h)
Returns a buffered volatile image optimized to this device, so that blitting can be supported in the buffered image. Because the buffer is volatile, it can be optimized by native graphics accelerators.
Overrides:
createCompatibleVolatileImage in interface GraphicsConfiguration
Parameters:
w - the width of the buffer
h - the height of the buffer
Returns:
the buffered image, or null if none is supported
Since:
1.4

createCompatibleVolatileImage

public VolatileImage createCompatibleVolatileImage(int width,
                                                   int height,
                                                   int transparency)
Overrides:
createCompatibleVolatileImage in interface GraphicsConfiguration
Since:
1.5

getBounds

public Rectangle getBounds()
Returns the bounds of the configuration, in device coordinates. If this is a virtual device (for example, encompassing several screens), the bounds may have a non-zero origin.
Overrides:
getBounds in interface GraphicsConfiguration
Returns:
the device bounds
Since:
1.3

getColorModel

public ColorModel getColorModel()
FIXME: I'm not sure which color model that should be returned here.
Overrides:
getColorModel in interface GraphicsConfiguration

getColorModel

public ColorModel getColorModel(int transparency)
Gets a color model for the corresponding device which supports the desired transparency level.
Overrides:
getColorModel in interface GraphicsConfiguration
Parameters:
transparency - the transparency of the model
Returns:
the color model, with transparency

getDefaultTransform

public AffineTransform getDefaultTransform()
Returns a transform that maps user coordinates to device coordinates. The preferred mapping is about 72 user units to 1 inch (2.54 cm) of physical space. This is often the identity transform. The device coordinates have the origin at the upper left, with increasing x to the right, and increasing y to the bottom.
Overrides:
getDefaultTransform in interface GraphicsConfiguration
Returns:
the transformation from user space to device space

getDevice

public GraphicsDevice getDevice()
Gets the associated device that this configuration describes.
Overrides:
getDevice in interface GraphicsConfiguration
Returns:
the device

getNormalizingTransform

public AffineTransform getNormalizingTransform()
Returns a transform that maps user coordinates to device coordinates. The exact mapping is 72 user units to 1 inch (2.54 cm) of physical space. This is often the identity transform. The device coordinates have the origin at the upper left, with increasing x to the right, and increasing y to the bottom. Note that this is more accurate (and thus, sometimes more costly) than the default transform.
Overrides:
getNormalizingTransform in interface GraphicsConfiguration
Returns:
the normalized transformation from user space to device space
