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, and with the specified transparency, so that blitting can be supported in the buffered image.
Overrides:
createCompatibleImage in interface GraphicsConfiguration
Parameters:
transparency - the transparency of the buffer
Returns:
the buffered image, or null if none is supported
See Also:
Transparency.OPAQUE, Transparency.BITMASK, Transparency.TRANSLUCENT

createCompatibleVolatileImage

public VolatileImage createCompatibleVolatileImage(int width,
                                                   int height)
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:
Returns:
the buffered image, or null if none is supported
Since:
1.4
See Also:
Component.createVolatileImage(int,int)

createCompatibleVolatileImage

public VolatileImage createCompatibleVolatileImage(int width,
                                                   int height,
                                                   int transparency)
Returns a buffered volatile image optimized to this device, and with the given transparency. Because the buffer is volatile, it can be optimized by native graphics accelerators.
Overrides:
createCompatibleVolatileImage in interface GraphicsConfiguration
Parameters:
width - the width of the buffer
height - the height of the buffer
transparency - the transparency value for the buffer
Returns:
the buffered image, or null if none is supported
Since:
1.5

createCompatibleVolatileImage

public VolatileImage createCompatibleVolatileImage(int width,
                                                   int height,
                                                   ImageCapabilities caps)
Returns a buffered volatile image optimized to this device, and with the given capabilities, 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:
caps - the desired capabilities of the image buffer
Returns:
the buffered image, or null if none is supported
Since:
1.4

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()
Gets the color model of the corresponding device.
Overrides:
getColorModel in interface GraphicsConfiguration
Returns:
the color model

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
See Also:
Transparency.OPAQUE, Transparency.BITMASK, Transparency.TRANSLUCENT

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
See Also:
GraphicsConfiguration.getNormalizingTransform()

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 the transform which transforms from this display's resolution to a 72 DPI resolution.
Overrides:
getNormalizingTransform in interface GraphicsConfiguration
