Class QtScreenDeviceConfiguration
BufferedImage | createCompatibleImage(int width, int height)- Returns a buffered image optimized to this device, so that blitting can
be supported in the buffered image.
|
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.

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.
|
VolatileImage | createCompatibleVolatileImage(int width, int height, int transparency)- Returns a buffered volatile image optimized to this device, and
with the given transparency.
|
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.

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.
- createCompatibleImage in interface GraphicsConfiguration
transparency - the transparency of the buffer
- the buffered image, or null if none is supported
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.
- createCompatibleVolatileImage in interface GraphicsConfiguration
width - the width of the bufferheight - the height of the buffertransparency - the transparency value for the buffer
- the buffered image, or null if none is supported
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.
- getBounds in interface GraphicsConfiguration
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.
- getDefaultTransform in interface GraphicsConfiguration
- the transformation from user space to device space
