Examples of javax.imageio.stream.ImageInputStream.readUnsignedShort()

javax.imageio.stream.ImageInputStream.readUnsignedShort()
Reads two bytes from the stream, and (conceptually) concatenates them according to the current byte order, converts the resulting value to an int, masks it with 0xffff in order to strip off any sign-extension buts, and returns the result as an unsigned int value.
The bit offset within the stream is reset to zero before the read occurs. @return an unsigned short value from the stream, as an int. @exception java.io.EOFException if the stream reaches the end beforereading all the bytes. @exception IOException if an I/O error occurs. @see #getByteOrder
