# Package java.awt.image

package java.awt.image
Provides classes for creating and modifying images. Images are processed using a streaming framework that involves an image producer, optional image filters, and an image consumer. This framework makes it possible to progressively render an image while it is being fetched and generated. Moreover, the framework allows an application to discard the storage used by an image and to regenerate it at any time. This package provides a number of image producers, consumers, and filters that you can configure for your image processing needs.

  Description
  AbstractMultiResolutionImage
  This class provides default implementations of several `Image` methods for classes that want to implement the `MultiResolutionImage` interface.
  AffineTransformOp
  This class uses an affine transform to perform a linear mapping from 2D coordinates in the source image or `Raster` to 2D coordinates in the destination image or `Raster`.

  This class performs an arbitrary linear combination of the bands in a `Raster`, using a specified matrix.

  This class is an array-based implementation of the `AbstractMultiResolutionImage` class.
  BufferedImage
  The `BufferedImage` subclass describes an `Image` with an accessible buffer of image data.
  BufferedImageFilter
  The `BufferedImageFilter` class subclasses an `ImageFilter` to provide a simple means of using a single-source/single-destination image operator (`BufferedImageOp`) to filter a `BufferedImage` in the Image Producer/Consumer/Observer paradigm.
  BufferedImageOp
  This interface describes single-input/single-output operations performed on `BufferedImage` objects.
  BufferStrategy
  The `BufferStrategy` class represents the mechanism with which to organize complex memory on a particular `Canvas` or `Window`.

  ColorConvertOp
  This class performs a pixel-by-pixel color conversion of the data in the source image.
  ColorModel
  The `ColorModel` abstract class encapsulates the methods for translating a pixel value to color components (for example, red, green, and blue) and an alpha component.
  ComponentColorModel
  A `ColorModel` class that works with pixel values that represent color and alpha information as separate samples and that store each sample in a separate data element.
  ComponentSampleModel
  This class represents image data which is stored such that each sample of a pixel occupies one data element of the DataBuffer.
  ConvolveOp
  This class implements a convolution from the source to the destination.
  CropImageFilter
  An ImageFilter class for cropping images.
  DataBuffer

  DataBufferUShort
  This class extends `DataBuffer` and stores data internally as shorts.

  FilteredImageSource
  This class is an implementation of the ImageProducer interface which takes an existing image and a filter object and uses them to produce image data for a new filtered version of the original image.
  ImageConsumer
  The interface for objects expressing interest in image data through the ImageProducer interfaces.
  ImageFilter
  This class implements a filter for the set of interface methods that are used to deliver data from an ImageProducer to an ImageConsumer.
  ImageObserver
  An asynchronous update interface for receiving notifications about Image information as the Image is constructed.
  ImageProducer
  The interface for objects which can produce the image data for Images.
  ImagingOpException
  The `ImagingOpException` is thrown if one of the `BufferedImageOp` or `RasterOp` filter methods cannot process the image.
  IndexColorModel
  The `IndexColorModel` class is a `ColorModel` class that works with pixel values consisting of a single sample that is an index into a fixed colormap in the default sRGB color space.
  Kernel
  The `Kernel` class defines a matrix that describes how a specified pixel and its surrounding pixels affect the value computed for the pixel's position in the output image of a filtering operation.
  LookupOp
  This class implements a lookup operation from the source to the destination.
  LookupTable
  This abstract class defines a lookup table object.
  MemoryImageSource
  This class is an implementation of the ImageProducer interface which uses an array to produce pixel values for an Image.
  MultiPixelPackedSampleModel
  The `MultiPixelPackedSampleModel` class represents one-banded images and can pack multiple one-sample pixels into one data element.
  MultiResolutionImage
  This interface is designed to be an optional additional API supported by some implementations of `Image` to allow them to provide alternate images for various rendering resolutions.
  PackedColorModel
  The `PackedColorModel` class is an abstract `ColorModel` class that works with pixel values which represent color and alpha information as separate samples and which pack all samples for a single pixel into a single int, short, or byte quantity.
  PixelGrabber
  The PixelGrabber class implements an ImageConsumer which can be attached to an Image or ImageProducer object to retrieve a subset of the pixels in that image.
  PixelInterleavedSampleModel
  This class represents image data which is stored in a pixel interleaved fashion and for which each sample of a pixel occupies one data element of the DataBuffer.
