function varargout = ImageReader(varargin)
% ImageReader MATLAB code for ImageReader.fig
% ImageReader, by itself, creates a new ImageReader or raises the existing
% singleton*.
%
% H = ImageReader returns the handle to a new ImageReader or the handle to
% the existing singleton*.
%
% ImageReader('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in ImageReader.M with the given input arguments.
%
% ImageReader('Property','Value',...) creates a new ImageReader or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before ImageReader_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to ImageReader_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
