Hi everyone,
I'm trying to read a picture file and get the size of the picture and print it to txt file. I want it like:
size img1.png
2448 3264 3
size img2.png
2458 3464 3
........
But i don't know how to do it, please help me with the code.
Here my code:
fork = 1: length(jpgFiles)
baseFileName = jpgFiles(k).name;
fullFileName = fullfile(Folder, baseFileName);
fprintf(1,'Reading %s\n', fullFileName);
imageArray = imread(fullFileName);
E=size(imageArray);
fid=fopen('Result.txt','a');
fprintf(fid,'%.d\n',E);
fclose(fid);
Thank you very much!

fprintf(fid,“% d % d % d \ n”, E);
It is much faster to open the file once only:
fid = fopen('Result.txt','a');
fork = 1:length(jpgFiles)
baseFileName = jpgFiles(k).name;
fullFileName = fullfile(Folder, baseFileName);
fprintf(1,'Reading %s\n', fullFileName);
imageArray = imread(fullFileName);
E = size(imageArray)
fprintf(fid,'size %s\n', baseFileName);% [EDITED]
fprintf(fid,“% d % d % d \ n”, E);
end
fclose(fid);
