    Methods in javax.imageio that return ImageWriteParam
    Modifier and Type | Method and 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 and 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.
    `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.
    `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.

  - ### Uses of ImageWriteParam in javax.imageio.plugins.bmp

    Subclasses of ImageWriteParam in javax.imageio.plugins.bmp
    Modifier and Type | Class and Description
    --- | ---
    `class` | `BMPImageWriteParam` A subclass of `ImageWriteParam` for encoding images in the BMP format.

  - ### Uses of ImageWriteParam in javax.imageio.plugins.jpeg

    Subclasses of ImageWriteParam in javax.imageio.plugins.jpeg
    Modifier and Type | Class and Description
    --- | ---
    `class` | `JPEGImageWriteParam` This class adds the ability to set JPEG quantization and Huffman tables when using the built-in JPEG writer plug-in, and to request that optimized Huffman tables be computed for an image.
