To generate hashes and store it in the ./hashes folder,

1) sudo make hash
	(set resoluton in DPI by passing argument
	example: sudo make DPI=100, if not specified,default is 72)

2) Usage   ./hash <font_file> <pt_size> <render_mode>
	
    Hashes will be saved in a file named 
    $(font)_$(pt_size)_$(render_mode).hash 

    By default, hashes of 256-level gray bitmaps will be generated

    Values for render_mode    0 - monochrome
                              1 - anti-aliased
                              2 - lcd horizontal
                              3 - lcd vertical

To generate 32-bit RGBA PNG(s) of all glyphs in a font\n
  
1) sudo make png
	(set resoluton in DPI by passing argument
  	example: sudo make DPI=100, if not specified,default is 72)

2.Usage   ./<exe> <font_file> <pt_size> <render_mode>

    Images will be saved in a file named 
    $(font)_$(pt_size)_$(render_mode)_$(glyph_index).png

    By default, hashes of 256-level gray bitmaps will be generated

    Values for render_mode    0 - monochrome
                              1 - anti-aliased
                              2 - lcd horizontal-RGB
                              3 - lcd horizontal-BGR
                              4 - lcd vertical-RGB
                              5 - lcd vertical-BGR
