/**
* Gets a buffered image specified by the byte source.
* The TiffImageParser class features support for a number of options that
* are unique to the TIFF format. These options can be specified by
* supplying the appropriate parameters using the keys from the
* TiffConstants class and the params argument for this method.
* <h4>Loading Partial Images</h4>
* The TIFF parser includes support for loading partial images without
* committing significantly more memory resources than are necessary
* to store the image. This feature is useful for conserving memory
* in applications that require a relatively small sub image from a
* very large TIFF file. The specifications for partial images are
* as follows:
* <code><pre>
* HashMap<String, Object> params = new HashMap<String, Object>();
* params.put(TiffConstants.PARAM_KEY_SUBIMAGE_X, new Integer(x));
* params.put(TiffConstants.PARAM_KEY_SUBIMAGE_Y, new Integer(y));
* params.put(TiffConstants.PARAM_KEY_SUBIMAGE_WIDTH, new Integer(width));
* params.put(TiffConstants.PARAM_KEY_SUBIMAGE_HEIGHT, new Integer(height));
* </pre></code>
* Note that the arguments x, y, width, and height must specify a
* valid rectangular region that is fully contained within the
* source TIFF image.
* @param byteSource A valid instance of ByteSource
* @param params Optional instructions for special-handling or
* interpretation of the input data (null objects are permitted and
* must be supported by implementations).
* @return A valid instance of BufferedImage.
* @throws ImageReadException In the event that the the specified
* content does not conform to the format of the specific parser
* implementation.
* @throws IOException In the event of unsuccessful read or
* access operation.
