Class XGraphicsConfiguration

public BufferedImage createCompatibleImage(int w,
                                           int h)

Returns a buffered image optimized to this device, so that blitting can be supported in the buffered image.

Overrides:

createCompatibleImage 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

public BufferedImage createCompatibleImage(int w,
                                           int h,
                                           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:

w - the width of the buffer

h - the height of the buffer

transparency - the transparency of the buffer

Returns:

the buffered image, or null if none is supported

Transparency.OPAQUE, Transparency.BITMASK, Transparency.TRANSLUCENT

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

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

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

public ColorModel getColorModel()

Gets the color model of the corresponding device.

Overrides:

getColorModel in interface GraphicsConfiguration

Returns:

the color model

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

Transparency.OPAQUE, Transparency.BITMASK, Transparency.TRANSLUCENT

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()

public GraphicsDevice getDevice()

Gets the associated device that this configuration describes.

Overrides:

getDevice in interface GraphicsConfiguration

Returns:

the device

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

GraphicsConfiguration.getDefaultTransform()
