## Uses of ImageWriteParam in javax.imageio

Methods in javax.imageio that return ImageWriteParam
Modifier and Type
Method
Description
`ImageWriteParam`
ImageWriter.`getDefaultWriteParam()`
Returns a new `ImageWriteParam` object of the appropriate type for this file format containing default values, that is, those values that would be used if no `ImageWriteParam` object were specified.
Methods in javax.imageio with parameters of type ImageWriteParam
Modifier and Type
Method
Description
`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.
`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.`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.
`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.`replacePixels(Raster raster, ImageWriteParam param)`
Replaces a portion of an image already present in the output with a portion of the given `Raster`.
`void`
ImageWriter.`replacePixels(RenderedImage image, ImageWriteParam param)`
Replaces a portion of an image already present in the output with a portion of the given image.
`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.
`void`
ImageWriter.`writeInsert(int imageIndex, IIOImage image, ImageWriteParam param)`
Inserts a new image into an existing image stream.
`void`
ImageWriter.`writeToSequence(IIOImage image, ImageWriteParam param)`
Appends a single image and possibly associated metadata and thumbnails, to the output.
