Examples of java.awt.image.BufferedImage

java.awt.image.BufferedImage
The BufferedImage subclass describes an {@link java.awt.Image Image} with an accessible buffer of image data.A BufferedImage is comprised of a {@link ColorModel} and a{@link Raster} of image data.The number and types of bands in the {@link SampleModel} of theRaster must match the number and types required by the ColorModel to represent its color and alpha components. All BufferedImage objects have an upper left corner coordinate of (0, 0). Any Raster used to construct a BufferedImage must therefore have minX=0 and minY=0.
This class relies on the data fetching and setting methods of Raster, and on the color characterization methods of ColorModel. @see ColorModel @see Raster @see WritableRaster @version 10 Feb 1997
