- - ### Uses of ImageReadParam in javax.imageio

    Methods in javax.imageio that return ImageReadParam
    Modifier and Type | Method | Description
    --- | --- | ---
    `ImageReadParam` | ImageReader.`getDefaultReadParam()` | Returns a default `ImageReadParam` object appropriate for this format.

    Methods in javax.imageio with parameters of type ImageReadParam
    Modifier and Type | Method | Description
    --- | --- | ---
    `protected static void` | ImageReader.`checkReadParamBandSettings​(ImageReadParam param, int numSrcBands, int numDstBands)` | A utility method that may be used by readers to test the validity of the source and destination band settings of an `ImageReadParam`.
    `protected static void` | ImageReader.`computeRegions​(ImageReadParam param, int srcWidth, int srcHeight, BufferedImage image, Rectangle srcRegion, Rectangle destRegion)` | Computes the source region of interest and the destination region of interest, taking the width and height of the source image, an optional destination image, and an optional `ImageReadParam` into account.
    `protected static BufferedImage` | ImageReader.`getDestination​(ImageReadParam param, Iterator<ImageTypeSpecifier> imageTypes, int width, int height)` | Returns the `BufferedImage` to which decoded pixel data should be written.
    `protected static Rectangle` | ImageReader.`getSourceRegion​(ImageReadParam param, int srcWidth, int srcHeight)` | A utility method that may be used by readers to compute the region of the source image that should be read, taking into account any source region and subsampling offset settings in the supplied `ImageReadParam`.
    `abstract BufferedImage` | ImageReader.`read​(int imageIndex, ImageReadParam param)` | Reads the image indexed by `imageIndex` and returns it as a complete `BufferedImage`, using a supplied `ImageReadParam`.
    `IIOImage` | ImageReader.`readAll​(int imageIndex, ImageReadParam param)` | Reads the image indexed by `imageIndex` and returns an `IIOImage` containing the image, thumbnails, and associated image metadata, using a supplied `ImageReadParam`.
    `RenderedImage` | ImageReader.`readAsRenderedImage​(int imageIndex, ImageReadParam param)` | Returns a `RenderedImage` object that contains the contents of the image indexed by `imageIndex`.
    `Raster` | ImageReader.`readRaster​(int imageIndex, ImageReadParam param)` | Returns a new `Raster` object containing the raw pixel data from the image stream, without any color conversion applied.

    Method parameters in javax.imageio with type arguments of type ImageReadParam
    Modifier and Type | Method | Description
    --- | --- | ---
    `Iterator<IIOImage>` | ImageReader.`readAll​(Iterator<? extends ImageReadParam> params)` | Returns an `Iterator` containing all the images, thumbnails, and metadata, starting at the index given by `getMinIndex`, from the input source in the form of `IIOImage` objects.

    Subclasses of ImageReadParam in javax.imageio.plugins.jpeg
    Modifier and Type | Class | Description
    --- | --- | ---
    `class` | `JPEGImageReadParam` | This class adds the ability to set JPEG quantization and Huffman tables when using the built-in JPEG reader plug-in.

  - ### Uses of ImageReadParam in javax.imageio.plugins.tiff

    Subclasses of ImageReadParam in javax.imageio.plugins.tiff
    Modifier and Type | Class | Description
    --- | --- | ---
    `class` | `TIFFImageReadParam` | A subclass of `ImageReadParam` allowing control over the TIFF reading process.
