converting .*fig image in to text file

i have to convert the attached .*fig grayscale image in to text file

What application created the .fig file? Was it MATLAB'S GUIDE? If so, that is not a regular image file like bmp, tiff, jpg, png, etc. How was this "image" saved? Can you change the way it is saved so that it saves it as a regular jpg image file format like you really want?

@Sabarinathan, I totally agree with your comment except for the suggestion of using jpg for the image format.

JPEG is totally unsuitable for accurately preserving the value of each pixel due to the lossy compression. With this image in particular, the fine checkerboard pattern would be ruined by JPEG. PNG is a much better format for this. Non-lossy and still good compression.
