## Uses of Class
javax.imageio.ImageReader

Packages that use ImageReader
javax.imageio: The main package of the Java Image I/O API.
javax.imageio.event: A package of the Java Image I/O API dealing with synchronous notification of events during the reading and writing of images.
javax.imageio.spi: A package of the Java Image I/O API containing the plug-in interfaces for readers, writers, transcoders, and streams, and a runtime registry.

### Uses of ImageReader in javax.imageio

Methods in javax.imageio that return ImageReader
`static ImageReader` ImageIO.`getImageReader(ImageWriter writer)` Returns an `ImageReader` corresponding to the given `ImageWriter`, if there is one, or `null` if the plug-in for this `ImageWriter` does not specify a corresponding `ImageReader`, or if the given `ImageWriter` is not registered.

Methods in javax.imageio that return types with arguments of type ImageReader
`static Iterator<ImageReader>` ImageIO.`getImageReaders(Object input)` Returns an `Iterator` containing all currently registered `ImageReader`s that claim to be able to decode the supplied `Object`, typically an `ImageInputStream`.
`static Iterator<ImageReader>` ImageIO.`getImageReadersByFormatName(String formatName)` Returns an `Iterator` containing all currently registered `ImageReader`s that claim to be able to decode the named format.
`static Iterator<ImageReader>` ImageIO.`getImageReadersByMIMEType(String MIMEType)` Returns an `Iterator` containing all currently registered `ImageReader`s that claim to be able to decode files with the given MIME type.
`static Iterator<ImageReader>` ImageIO.`getImageReadersBySuffix(String fileSuffix)` Returns an `Iterator` containing all currently registered `ImageReader`s that claim to be able to decode files with the given suffix.

Methods in javax.imageio with parameters of type ImageReader
`static Iterator<ImageTranscoder>` ImageIO.`getImageTranscoders(ImageReader reader, ImageWriter writer)` Returns an `Iterator` containing all currently registered `ImageTranscoder`s that claim to be able to transcode between the metadata of the given `ImageReader` and `ImageWriter`.
`static ImageWriter` ImageIO.`getImageWriter(ImageReader reader)` Returns an `ImageWriter` corresponding to the given `ImageReader`, if there is one, or `null` if the plug-in for this `ImageReader` does not specify a corresponding `ImageWriter`, or if the given `ImageReader` is not registered.

### Uses of ImageReader in javax.imageio.event

Methods in javax.imageio.event with parameters of type ImageReader
`void` IIOReadProgressListener.`imageComplete(ImageReader source)` Reports that the current image read operation has completed.
`void` IIOReadProgressListener.`imageProgress(ImageReader source, float percentageDone)` Reports the approximate degree of completion of the current `read` call of the associated `ImageReader`.
`void` IIOReadProgressListener.`imageStarted(ImageReader source, int imageIndex)` Reports that an image read operation is beginning.
`void` IIOReadUpdateListener.`imageUpdate(ImageReader source, BufferedImage theImage, int minX, int minY, int width, int height, int periodX, int periodY, int[] bands)` Reports that a given region of the image has been updated.
`void` IIOReadUpdateListener.`passComplete(ImageReader source, BufferedImage theImage)` Reports that the current read operation has completed a progressive pass.
`void` IIOReadUpdateListener.`passStarted(ImageReader source, BufferedImage theImage, int pass, int minPass, int maxPass, int minX, int minY, int periodX, int periodY, int[] bands)` Reports that the current read operation is about to begin a progressive pass.
`void` IIOReadProgressListener.`readAborted(ImageReader source)` Reports that a read has been aborted via the reader's `abort` method.
`void` IIOReadProgressListener.`sequenceComplete(ImageReader source)` Reports that a sequence of read operations has completed.
`void` IIOReadProgressListener.`sequenceStarted(ImageReader source, int minIndex)` Reports that a sequence of read operations is beginning.
`void` IIOReadProgressListener.`thumbnailComplete(ImageReader source)` Reports that a thumbnail read operation has completed.
`void` IIOReadUpdateListener.`thumbnailPassComplete(ImageReader source, BufferedImage theThumbnail)` Reports that the current thumbnail read operation has completed a progressive pass.
`void` IIOReadUpdateListener.`thumbnailPassStarted(ImageReader source, BufferedImage theThumbnail, int pass, int minPass, int maxPass, int minX, int minY, int periodX, int periodY, int[] bands)` Reports that the current thumbnail read operation is about to begin a progressive pass.
`void` IIOReadProgressListener.`thumbnailProgress(ImageReader source, float percentageDone)` Reports the approximate degree of completion of the current `getThumbnail` call within the associated `ImageReader`.
`void` IIOReadProgressListener.`thumbnailStarted(ImageReader source, int imageIndex, int thumbnailIndex)` Reports that a thumbnail read operation is beginning.
`void` IIOReadUpdateListener.`thumbnailUpdate(ImageReader source, BufferedImage theThumbnail, int minX, int minY, int width, int height, int periodX, int periodY, int[] bands)` Reports that a given region of a thumbnail image has been updated.
`void` IIOReadWarningListener.`warningOccurred(ImageReader source, String warning)` Reports the occurrence of a non-fatal error in decoding.

### Uses of ImageReader in javax.imageio.spi

Methods in javax.imageio.spi that return ImageReader
`ImageReader` ImageReaderSpi.`createReaderInstance()` Returns an instance of the `ImageReader` implementation associated with this service provider.
`abstract ImageReader` ImageReaderSpi.`createReaderInstance(Object extension)` Returns an instance of the `ImageReader` implementation associated with this service provider.

Methods in javax.imageio.spi with parameters of type ImageReader
`boolean` ImageReaderSpi.`isOwnReader(ImageReader reader)` Returns `true` if the `ImageReader` object passed in is an instance of the `ImageReader` associated with this service provider.
