conversion of image file into binary txt file

I have converted the image file into binary txt file using this: I = imread ('app-log-icon.png') Y = rgb2gray(I) level = graythresh(Y) BW = im2bw(Y,level) Z = imresize(Y,[40 40]) dlmwrite('C:\Users\Prasann\Desktop\new.txt',BW,' ') But i dont want any space or Comma between two elements so how should i proceed with this problem as i have to call this binary txt file in my verilog coding thank u

Hi megha

You can do the following

 Urbinary = [0 1 0 0 1 0 1 0; % it says hi by the way!
             0 1 0 0 1 0 1 0;
             0 1 1 1 1 0 1 0;
             0 1 0 0 1 0 1 0;
             0 1 0 0 1 0 1 0]

 [rows, cols] = size(Urbinary);
 bins = cell(rows*cols,1);
 bin_vect = reshape(Urbinary, rows*cols,1);

 for i = 1:size(bin_vect) 
     bins{i} = num2str(bin_vect(i)); % convert to strings and put in a cell
 end

 bin_shape = reshape(bins,rows,cols);
 char_bin = reshape(horzcat(bin_shape{:}),rows,cols); concatenate and reshape back to original 

 % write to desired location
 [filename, pathname] = uiputfile('*.txt', 'Locate directory for to write .txt file to');
 outpath = strcat(pathname,filename);

 fid = fopen(outpath,'w');
    for i=1: size(char_bin,1)
        fprintf(fid,'%s\r\n',char_bin(i,:));
    end
 fclose(fid);

Hope this helps

Can't you just do

fprintf(fid, '%d ', Z); % Write 0 or 1 a followed by a space.

? It should write out the whole array that way in a single call to fprintf().
