Introduction: 
This img_cvt.exe is the utility which runs on Windows to convert the image of PNG and JPEG

The usage is : 
    img_cvt  -i  inputfilename  -f  format

         format is as follow:
            0 : ARGB1555 [default]
            1 : L1

    Programmer can include this file into their program and build it into final binary. 

*.bin  : The compressed binary format of converted file in ZLIB algorithm. Programmer needs download it 
   into graphics memory of FT800 and use CMD_INFLATE to inflate them before using it.
