i have created converted imgae to binary and then write it using fprintf commant on a text file. this text file will become as an input file for arduino. text file is attached here. but when i open it. its actually not a binary file. i need to input binary file to arduino.please help me how do i formulate this file to be understanble by arduino. please help me in this regard.

% Calculate relative displacement between neighboring path points for stepper motor commands and save to text file
xPath=-xPath;
yPath=yPath;
xPathRel=diff(xPath);
yPathRel=diff(yPath);
textFile=fopen('drawing.txt','w'); %Create new file called drawing.txt
for i=1:1:size(xPathRel,2) %Write alternativing X,Y waypoints on new lines
fprintf(textFile, '%d\n', yPathRel(i));
fprintf(textFile, '%d\n', xPathRel(i));
end
fclose(textFile); %Close the text file
textFile = fopen('drawing.txt','r');
Halftoning is applied here and then drawing.text file is created. complete code is also given above.
