### Uses of IIOMetadata in javax.imageio

Fields in javax.imageio declared as IIOMetadata
`protected IIOMetadata` IIOImage.`metadata` An `IIOMetadata` object containing metadata associated with the image.

Methods in javax.imageio that return IIOMetadata
`IIOMetadata` ImageTranscoder.`convertImageMetadata(IIOMetadata inData, ImageTypeSpecifier imageType, ImageWriteParam param)` Returns an `IIOMetadata` object that may be used for encoding and optionally modified using its document interfaces or other interfaces specific to the writer plug-in that will be used for encoding.
`abstract IIOMetadata` ImageWriter.`convertImageMetadata(IIOMetadata inData, ImageTypeSpecifier imageType, ImageWriteParam param)`
`IIOMetadata` ImageTranscoder.`convertStreamMetadata(IIOMetadata inData, ImageWriteParam param)` Returns an `IIOMetadata` object that may be used for encoding and optionally modified using its document interfaces or other interfaces specific to the writer plug-in that will be used for encoding.
`abstract IIOMetadata` ImageWriter.`convertStreamMetadata(IIOMetadata inData, ImageWriteParam param)`
`abstract IIOMetadata` ImageWriter.`getDefaultImageMetadata(ImageTypeSpecifier imageType, ImageWriteParam param)` Returns an `IIOMetadata` object containing default values for encoding an image of the given type.
`abstract IIOMetadata` ImageWriter.`getDefaultStreamMetadata(ImageWriteParam param)` Returns an `IIOMetadata` object containing default values for encoding a stream of images.
`abstract IIOMetadata` ImageReader.`getImageMetadata(int imageIndex)` Returns an `IIOMetadata` object containing metadata associated with the given image, or `null` if the reader does not support reading metadata, is set to ignore metadata, or if no metadata is available.
`IIOMetadata` ImageReader.`getImageMetadata(int imageIndex, String formatName, Set<String> nodeNames)` Returns an `IIOMetadata` object representing the metadata associated with the given image, or `null` if the reader does not support reading metadata or none is available.
`IIOMetadata` IIOImage.`getMetadata()` Returns a reference to the current `IIOMetadata` object, or `null` is none is set.
`abstract IIOMetadata` ImageReader.`getStreamMetadata()` Returns an `IIOMetadata` object representing the metadata associated with the input source as a whole (i.e., not associated with any particular image), or `null` if the reader does not support reading metadata, is set to ignore metadata, or if no metadata is available.
`IIOMetadata` ImageReader.`getStreamMetadata(String formatName, Set<String> nodeNames)` Returns an `IIOMetadata` object representing the metadata associated with the input source as a whole (i.e., not associated with any particular image).

Methods in javax.imageio with parameters of type IIOMetadata
`IIOMetadata` ImageTranscoder.`convertImageMetadata(IIOMetadata inData, ImageTypeSpecifier imageType, ImageWriteParam param)` Returns an `IIOMetadata` object that may be used for encoding and optionally modified using its document interfaces or other interfaces specific to the writer plug-in that will be used for encoding.
`abstract IIOMetadata` ImageWriter.`convertImageMetadata(IIOMetadata inData, ImageTypeSpecifier imageType, ImageWriteParam param)`
`IIOMetadata` ImageTranscoder.`convertStreamMetadata(IIOMetadata inData, ImageWriteParam param)` Returns an `IIOMetadata` object that may be used for encoding and optionally modified using its document interfaces or other interfaces specific to the writer plug-in that will be used for encoding.
`abstract IIOMetadata` ImageWriter.`convertStreamMetadata(IIOMetadata inData, ImageWriteParam param)`
`int` ImageWriter.`getNumThumbnailsSupported(ImageTypeSpecifier imageType, ImageWriteParam param, IIOMetadata streamMetadata, IIOMetadata imageMetadata)` Returns the number of thumbnails supported by the format being written, given the image type and any additional write parameters and metadata objects that will be used during encoding.
`Dimension[]` ImageWriter.`getPreferredThumbnailSizes(ImageTypeSpecifier imageType, ImageWriteParam param, IIOMetadata streamMetadata, IIOMetadata imageMetadata)` Returns an array of `Dimension`s indicating the legal size ranges for thumbnail images as they will be encoded in the output file or stream.
`void` ImageWriter.`prepareInsertEmpty(int imageIndex, ImageTypeSpecifier imageType, int width, int height, IIOMetadata imageMetadata, List<? extends BufferedImage> thumbnails, ImageWriteParam param)` Begins the insertion of a new image with undefined pixel values into an existing image stream.
`void` ImageWriter.`prepareWriteEmpty(IIOMetadata streamMetadata, ImageTypeSpecifier imageType, int width, int height, IIOMetadata imageMetadata, List<? extends BufferedImage> thumbnails, ImageWriteParam param)` Begins the writing of a complete image stream, consisting of a single image with undefined pixel values and associated metadata and thumbnails, to the output.
`void` ImageWriter.`prepareWriteSequence(IIOMetadata streamMetadata)` Prepares a stream to accept a series of subsequent `writeToSequence` calls, using the provided stream metadata object.
`void` ImageWriter.`replaceImageMetadata(int imageIndex, IIOMetadata imageMetadata)` Replaces the image metadata associated with an existing image.
`void` ImageWriter.`replaceStreamMetadata(IIOMetadata streamMetadata)` Replaces the stream metadata in the output with new information.
`void` IIOImage.`setMetadata(IIOMetadata metadata)` Sets the `IIOMetadata` to a new object, or `null`.
`abstract void` ImageWriter.`write(IIOMetadata streamMetadata, IIOImage image, ImageWriteParam param)` Appends a complete image stream containing a single image and associated stream and image metadata and thumbnails to the output.
