Question

I have spent the last couple hours scouring the Internet for a solution to my problem, and while I have seen some “answers” on other forums, none of them suit my needs…

I have a binary file, which I am creating in Matlab using fwrite (although, if someone has a better way to generate a binary file in Matlab, I’m open to suggestions). Back to my problem – I have this binary file, and I want to convert it to a jpeg. Nevermind where the binary data comes from, I just want to generate a jpeg image of the binary data.

Is this even possible? – Like I said, lots of “solutions” out there to similar problems, but none match up to my needs.

I can write code in C++, if necessary, but for simplicity, I’d like to stay in Matlab.

Any help will be appreciated.

EDIT:

from binary to array:

fid = fopen('yourfilename.bin');

% read the entire file as characters
% transpose so that F is a row vector
B = fread(fid, '*char')'

fclose(fid);

Reshape to array according to image dimensions

C=reshape(B,512,512); % or whatever dimension you have 

Upon having the array of strings just use:

D=int32(str2num(C));
