saving an image in a specific folder

Hello,

i'm trying to save an image to a specific folder, however when i save the image i would like to give it any name i want.

similar to saving a word document, and a dialogue box pops up and asks you where would you like the destination folder and the name of the file

Use uiputfile to get the file name and path, e.g. where I is your image array:

[F,P] = uiputfile();
imwrite(I,fullfile(P,F))

would you be able to elaborate? i can't seem to get it to work

@hasan alhussaini: my answer contains a complete working example. If you are having problems please show the code that you tried.

[hasan alhussaini]

it works perfectly thank you!

just one last question. i get the error "Unable to determine the file format from the file name". therefore i added imwrite(I,fullfile(P,F),'tif')

i can save the image now. but i can't open it again... what am i doing wrong?

"i can save the image now. but i can't open it again... what am i doing wrong?"

How are you trying to open the image? With what application? Please show the output of this command:

whos I

where I is your image array. If possible please upload the image file by clicking the paperclip button.

this is the code i'm using. sinog_2 is the variablei'm trying to save

[F,P] = uiputfile(); %this code saves the sinogram imwrite(sinog_2,fullfile(P,F),'tif')

(i managed to save the file by clicking on the variable in the work space and clicking "save as", however i'm trying to achieve this simultaneously by coding)

Try this fix

if ~contains(F, '.tif', 'IgnoreCase', true)
   % User did not enter the .tif extension.  add it for them.
    F = [F, '.tif']; % Append .tif
end
fullFileName = fullfile(P, F);
imwrite(I, fullFileName);

You can use imsave():

img = imread('peppers.png');
imshow(img); % Display image
[filename, user_canceled] = imsave();

Or else the longer way with uiputfile():

% 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 % Or "pwd" or wherever you want.
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(yourImage, fullFileName);
