the class ImageReader method readAll.
/**
* Reads the image indexed by <code>imageIndex</code> and returns
* an <code>IIOImage</code> containing the image, thumbnails, and
* associated image metadata, using a supplied
* <code>ImageReadParam</code>.
*
* <p> The actual <code>BufferedImage</code> referenced by the
* returned <code>IIOImage</code> will be chosen using the
* algorithm defined by the <code>getDestination</code> method.
*
* <p> Any registered <code>IIOReadProgressListener</code> objects
* will be notified by calling their <code>imageStarted</code>
* method, followed by calls to their <code>imageProgress</code>
* method as the read progresses. Finally their
* <code>imageComplete</code> method will be called.
* <code>IIOReadUpdateListener</code> objects may be updated at
* other times during the read as pixels are decoded. Finally,
* <code>IIOReadWarningListener</code> objects will receive
* notification of any non-fatal warnings that occur during
* decoding.
*
* <p> The set of source bands to be read and destination bands to
* be written is determined by calling <code>getSourceBands</code>
* and <code>getDestinationBands</code> on the supplied
* <code>ImageReadParam</code>. If the lengths of the arrays
* returned by these methods differ, the set of source bands
* contains an index larger that the largest available source
* index, or the set of destination bands contains an index larger
* than the largest legal destination index, an
* <code>IllegalArgumentException</code> is thrown.
*
* <p> Thumbnails will be returned in their entirety regardless of
* the region settings.
*
* <p> If the supplied <code>ImageReadParam</code> contains
* optional setting values not supported by this reader (<i>e.g.</i>
* source render size or any format-specific settings), those
* values will be ignored.
*
* @param imageIndex the index of the image to be retrieved.
* @param param an <code>ImageReadParam</code> used to control
* the reading process, or <code>null</code>.
*
* @return an <code>IIOImage</code> containing the desired portion
* of the image, a set of thumbnails, and associated image
* metadata.
*
* @exception IllegalStateException if the input source has not been
* set.
* @exception IndexOutOfBoundsException if the supplied index is
* out of bounds.
* @exception IllegalArgumentException if the set of source and
* destination bands specified by
* <code>param.getSourceBands</code> and
* <code>param.getDestinationBands</code> differ in length or
* include indices that are out of bounds.
* @exception IllegalArgumentException if the resulting image
* would have a width or height less than 1.
* @exception IOException if an error occurs during reading.
