java.awt.image
Class BufferedImage
- RenderedImage, Transparency, WritableRenderedImage
A buffered image always starts at coordinates (0, 0).
The buffered image is not subdivided into multiple tiles. Instead,
the image consists of one large tile (0,0) with the width and
height of the image. This tile is always considered to be checked
out.

BufferedImage
public BufferedImage(int width,
int height,
int type) Creates a new
BufferedImage with the specified width, height
and type. Valid
type values are:
width - the width (must be > 0).height - the height (must be > 0).type - the image type (see the list of valid types above).
coerceData
public void coerceData(boolean premultiplied)
getRGB
public int getRGB(int x,
int y)
getRGB
public int[] getRGB(int startX,
int startY,
int w,
int h,
int[] rgbArray,
int offset,
int scanlineStride)
setRGB
public void setRGB(int x,
int y,
int argb)
setRGB
public void setRGB(int startX,
int startY,
int w,
int h,
int[] argbArray,
int offset,
int scanlineStride)
toString
public String toString()
Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into
System.out.println()
and such.
It is typical, but not required, to ensure that this method
never completes abruptly with a
RuntimeException.
This method will be called when performing string
concatenation with this object. If the result is
null, string concatenation will instead
use
"null".
The default implementation returns
getClass().getName() + "@" +
Integer.toHexString(hashCode()).
- toString in interface Object
- the String representing this Object, which may be null
