java.awt.image Documentation Differences

This file contains all the changes in documentation in the package java.awt.image as colored differences. Deletions are shown like this, and additions are shown like this.

If no deletions or additions are shown in an entry, the HTML tags will be what has changed. The new HTML tags are shown in the differences. If no documentation existed, and then some was added in a later version, this change is noted in the appropriate class pages of differences, but the change is not shown on this page. Only changes in existing text are shown here. Similarly, documentation which was inherited from another class or interface is not shown here.

Note that an HTML error in the new documentation may cause the display of other documentation changes to be presented incorrectly. For instance, failure to close a <code> tag will cause all subsequent paragraphs to be displayed differently.

An ImageFilter class for scaling images using a simple area averaging algorithm that produces smoother results than the nearest neighbor algorithm.

This class extends the basic ImageFilter Class to scale an existing image and provide a source for a new image containing the resampled image. The pixels in the source image are blended to produce pixels for an image of the specified size. The blending process is analogous to scaling up the source image to a multiple of the destination size using pixel replication and then scaling it back down to the destination size by simply averaging all the pixels in the supersized image that fall within a given pixel of the destination image. If the data from the source is not delivered in TopDownLeftRight order then the filter will back off to a simple pixel replication behavior and utilize the requestTopDownLeftRightResend() method to refilter the pixels in a better way at the end.

It is meant to be used in conjunction with a FilteredImageSource object to produce scaled versions of existing images. Due to implementation dependencies there may be differences in pixel values of an image filtered on different platforms. @see FilteredImageSource @see ReplicateScaleFilter @see ImageFilter @version 1.11 1213 04/0319/0102 @author Jim Graham

Returns the height of the BufferedImage. @return the height of this BufferedImage.

Returns the actual height of the image. If the height is not known yet then the ImageObserver is notified later and -1BufferedImage is returned. @param observer the ImageObserver that receives information about the imageignored @return the height of the imagethis or -1BufferedImage if the height is not yet known. @see java.awt.Image#getWidth(ImageObserver) @see ImageObserver

Returns the width of the BufferedImage. @return the width of this BufferedImage.

Returns the actual width of the image. If the width is not known yet then the ImageObserver is notified later and -1BufferedImage is returned. @param observer the ImageObserver thatignored receives information about the image @return the width of the image orthis -1BufferedImage if the width is not yet known. @see java.awt.Image#getHeight(ImageObserver) @see ImageObserver

Represents an image with 8-bit RGB color components corresponding to a Windows- or Solaris- style BGR color model with the colors Blue Green and Red packed into integer pixels. There is no alpha. The image has a ComponentColorModelDirectColorModel

An ImageFilter class for scaling images using the simplest algorithm. This class extends the basic ImageFilter Class to scale an existing image and provide a source for a new image containing the resampled image. The pixels in the source image are sampled to produce pixels for an image of the specified size by replicating rows and columns of pixels to scale up or omitting rows and columns of pixels to scale down.

It is meant to be used in conjunction with a FilteredImageSource object to produce scaled versions of existing images. Due to implementation dependencies there may be differences in pixel values of an image filtered on different platforms. @see FilteredImageSource @see ImageFilter @version 1.1415 12/03/01/02 @author Jim Graham
