How to save image using Guide GUI?

I'm trying to save an image in a TIFF format by opening a dialog box and choosing the location and the name.I know the below code opens dialog box but nothing will happen when I click save.

[FileName,PathName]= uiputfile('*.tiff','Save Workspace As');

How do I save my images?

uiputfile() simply gets a filename. You still have to call imwrite() to to the actual writing to disk. Try this:

% Get the name of the file that the user wants to save.
% Note, if you're saving an image you can use imsave() instead of uiputfile().
startingFolder = userpath
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a file');
if baseFileName == 0
  % User clicked the Cancel button.
  return;
end
fullFileName = fullfile(folder, baseFileName)
imwrite(yourImageArray, fullFileName);

So I'm guessing 'Specify a file' means which image I want to save? What is yourImageArray and '*.*'?

You can put whatever prompt you like. If you don't like "Specify a file" you can choose "Browse to the folder you want and type in the name you want the image to take once it is saved on your drive" - or whatever you want.

What did you call your variable that has the image you want to save? Use that name instead of yourImageArray.

Awesome, Thank you!

I still don't understand the yourimagearray and specify a file part, can you please explain it to me and where can i find them (I really need this for a project)

You have an image in your program, right? Well, what is the name of the variable that you used? Whatever it is, replace yourImageArray with the actual name of your variable. It's not yourImageArray (the name I chose) - it's whatever name you chose to give to your image variable, like the return value from imread() when you called that to read your image in from disk.

As far as how uiputfile() works, just read the documentation.
