        public boolean isLoadEagerly()

      • setLoadEagerly

        public void setLoadEagerly​(boolean pLoadEagerly)
        Instructs the reader wether it should read and cache alle thumbnails in sequence, during the first read operation.

        This is useful mainly if you need to read all the thumbnails, and you need them in random order, as it requires less repositioning in the underlying stream.

        Parameters:
        pLoadEagerly - true if the reader should read all thumbs on first read

      • read

        public java.awt.image.BufferedImage read​(int pIndex,
                                         javax.imageio.ImageReadParam pParam)
                                  throws java.io.IOException
        Reads the image data from the given input stream, and returns it as a BufferedImage.
        Specified by:
        read in class javax.imageio.ImageReader
        Parameters:
        pIndex - the index of the image to read
        pParam - additional parameters used while decoding, may be null, in which case defaults will be used
        Returns:
        a BufferedImage
        Throws:
        java.lang.IndexOutOfBoundsException - if pIndex is out of bounds
        java.lang.IllegalStateException - if the input source has not been set
        java.io.IOException - if an error occurs during reading

                                  throws java.io.IOException
        Reads the image data from the given input stream, and returns it as a BufferedImage.
        Parameters:
        pName - the name of the image to read
        pParam - additional parameters used while decoding, may be null, in which case defaults will be used
        Returns:
        a BufferedImage
        Throws:
        java.io.FileNotFoundException - if the given file name is not found in the "Catalog" entry of the CompoundDocument
