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.
RasterFormatException	The RasterFormatException is thrown if there is invalid layout information in the Raster.
