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.

Interface Summary
Interface Description
BufferedImageOp

This interface describes single-input/single-output operations performed on BufferedImage objects.

ImageConsumer

The interface for objects expressing interest in image data through the ImageProducer interfaces.

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.

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.

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.

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.

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.

Class Summary
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.

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.

ImageFilter

This class implements a filter for the set of interface methods that are used to deliver data from an ImageProducer to an ImageConsumer.

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.

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.

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

This class provides an easy way to create an ImageFilter which modifies the pixels of an image in the default RGB ColorModel.

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.

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.

Exception Summary
Exception Description
ImagingOpException

The ImagingOpException is thrown if one of the BufferedImageOp or RasterOp filter methods cannot process the image.
