Uses of ImageReadParam in javax.imageio
Methods in javax.imageio that return ImageReadParam Modifier and Type Method and Description ImageReadParamImageReader. getDefaultReadParam()Returns a defaultImageReadParamobject appropriate for this format.Methods in javax.imageio with parameters of type ImageReadParam Modifier and Type Method and Description protected static voidImageReader. 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 anImageReadParam.protected static voidImageReader. 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 optionalImageReadParaminto account.protected static BufferedImageImageReader. getDestination(ImageReadParam param, Iterator<ImageTypeSpecifier> imageTypes, int width, int height)Returns theBufferedImageto which decoded pixel data should be written.protected static RectangleImageReader. 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 suppliedImageReadParam.abstract BufferedImageImageReader. read(int imageIndex, ImageReadParam param)Reads the image indexed byimageIndexand returns it as a completeBufferedImage, using a suppliedImageReadParam.IIOImageImageReader. readAll(int imageIndex, ImageReadParam param)Reads the image indexed byimageIndexand returns anIIOImagecontaining the image, thumbnails, and associated image metadata, using a suppliedImageReadParam.RenderedImageImageReader. readAsRenderedImage(int imageIndex, ImageReadParam param)Returns aRenderedImageobject that contains the contents of the image indexed byimageIndex.RasterImageReader. readRaster(int imageIndex, ImageReadParam param)Returns a newRasterobject 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 and Description Iterator<IIOImage>ImageReader. readAll(Iterator<? extends ImageReadParam> params)Returns anIteratorcontaining all the images, thumbnails, and metadata, starting at the index given bygetMinIndex, from the input source in the form ofIIOImageobjects. -
