# 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.

Class
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`.
AreaAveragingScaleFilter
An ImageFilter class for scaling images using a simple area averaging algorithm that produces smoother results than the nearest neighbor algorithm.
BandCombineOp
This class performs an arbitrary linear combination of the bands in a `Raster`, using a specified matrix.
BandedSampleModel
This class represents image data which is stored in a band interleaved fashion and for which each sample of a pixel occupies one data element of the DataBuffer.
BaseMultiResolutionImage
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`.
ByteLookupTable
This class defines a lookup table object.
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
This class exists to wrap one or more data arrays.
DataBufferByte
This class extends `DataBuffer` and stores data internally as bytes.
DataBufferDouble
This class extends `DataBuffer` and stores data internally in `double` form.
DataBufferFloat
This class extends `DataBuffer` and stores data internally in `float` form.
DataBufferInt
This class extends `DataBuffer` and stores data internally as integers.
DataBufferShort
This class extends `DataBuffer` and stores data internally as shorts.
DataBufferUShort
This class extends `DataBuffer` and stores data internally as shorts.
DirectColorModel
The `DirectColorModel` class is a `ColorModel` class that works with pixel values that represent RGB color and alpha information as separate samples and that pack all samples for a single pixel into a single int, short, or byte quantity.
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.
Raster
A class representing a rectangular array of pixels.
RasterFormatException
The `RasterFormatException` is thrown if there is invalid layout information in the `Raster`.
RasterOp
This interface describes single-input/single-output operations performed on Raster objects.
RenderedImage
RenderedImage is a common interface for objects which contain or can produce image data in the form of Rasters.
ReplicateScaleFilter
An ImageFilter class for scaling images using the simplest algorithm.
RescaleOp
This class performs a pixel-by-pixel rescaling of the data in the source image by multiplying the sample values for each pixel by a scale factor and then adding an offset.
RGBImageFilter

SampleModel
This abstract class defines an interface for extracting samples of pixels in an image.
ShortLookupTable
This class defines a lookup table object.
SinglePixelPackedSampleModel
This class represents pixel data packed such that the N samples which make up a single pixel are stored in a single data array element, and each data data array element holds samples for only one pixel.
TileObserver
An interface for objects that wish to be informed when tiles of a WritableRenderedImage become modifiable by some writer via a call to getWritableTile, and when they become unmodifiable via the last call to releaseWritableTile.
VolatileImage
VolatileImage is an image which can lose its contents at any time due to circumstances beyond the control of the application (e.g., situations caused by the operating system or by other applications).
WritableRaster
This class extends Raster to provide pixel writing capabilities.
WritableRenderedImage
WritableRenderedImage is a common interface for objects which contain or can produce image data in the form of Rasters and which can be modified and/or written over.
