## 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.

Subclasses of ImageWriteParam in javax.imageio.plugins.bmp
Modifier and Type | Class | 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 | 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.
