%  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.
