% Method ReadTXTImage reads a text file and returns it as an image. It
% allocates the memory necessary for the new Image structure and returns a
% pointer to the new image.
%
% The format of the ReadTXTImage method is:
%
% Image *ReadTXTImage(const ImageInfo *image_info,ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: Method ReadTXTImage returns a pointer to the image after
% reading. A null image is returned if there is a memory shortage or if
% the image cannot be read.
%
% o image_info: Specifies a pointer to a ImageInfo structure.
%
% o exception: return any errors or warnings in this structure.
