Uses of ImageReadParam in javax.imageio

Methods in javax.imageio that return ImageReadParam

ImageReadParam

ImageReader.getDefaultReadParam() Returns a default ImageReadParam object appropriate for this format.

Methods in javax.imageio with parameters of type ImageReadParam

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

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.
