writing an image into folder

I have 100 images in an folder ,and have performed some operation on it ,now i have subplotted those images ,so now i have single figure window,now i want to write that figure window into an folder,i have created an folder,but dont know how to write that figure window,please help

I have posted the code

clc;
close all;

f1=fullfile('D:','new');
if (exist(f1) == 0)
   mkdir (f1);
end

pathname ='D:\dataset\' ;
 dirlist = dir( [pathname '*.jpg'] );
 pickind='jpg'; 

for m = 1:length(dirlist)

      rgbimage=double( imread([pathname, dirlist(x).name]));

% Read standard MATLAB demo image.
%rgbImage = imread('onion.png');

% Display the original image.
subplot(3, 4, 1);
imshow(rgbImage);
title('Original RGB Image');

% Maximize figure.
set(gcf, 'Position', get(0, 'ScreenSize'));

% Split the original image into color bands.
redBand = rgbImage(:,:, 1);
greenBand = rgbImage(:,:, 2);
blueBand = rgbImage(:,:, 3);

% Display them.
subplot(3, 4, 2);
imshow(redBand);
title('Red band');
subplot(3, 4, 3);
imshow(greenBand);
title('Green band');
subplot(3, 4, 4);
imshow(blueBand);
title('Blue Band');

% Threshold each color band.
redthreshold = 68;
greenThreshold = 70;
blueThreshold = 72;
redMask = (redBand > redthreshold);
greenMask = (greenBand < greenThreshold);
blueMask = (blueBand < blueThreshold);

% Display them.
subplot(3, 4, 6);
imshow(redMask, []);
title('Red Mask');
subplot(3, 4, 7);
imshow(greenMask, []);
title('Green Mask');
subplot(3, 4, 8);
imshow(blueMask, []);
title('Blue Mask');

% Combine the masks to find where all 3 are "true."
redObjectsMask = uint8(redMask & greenMask & blueMask);
subplot(3, 4, 9);
imshow(redObjectsMask, []);
title('Red Objects Mask');
maskedrgbImage = uint8(zeros(size(redObjectsMask))); % Initialize
maskedrgbImage(:,:,1) = rgbImage(:,:,1) .* redObjectsMask;
maskedrgbImage(:,:,2) = rgbImage(:,:,2) .* redObjectsMask;
maskedrgbImage(:,:,3) = rgbImage(:,:,3) .* redObjectsMask;
subplot(3, 4, 10);
imshow(maskedrgbImage);
title('Masked Original Image');
end

doc print

More to Clarify Comments

H = figure;
for ii = 321:326
  subplot(ii)
  imagesc(magic(ceil(rand*10))); %random fig with 6 subplots
end
print('-dbmp256' , 'picture_of_6_subplots') %save as bmp

I cant understand what u r saying ,can u explain please

[Sean de Wolski]

tpye:

doc print

at the command line and it will explain to you how to print your figure to an image.

Sean i want to write that image in a folder and not to print

[Sean de Wolski]

Did you read the documentation in doc print? If you choose your printer to be an image writer, you'll get an image. There are examples at the bottom.

Sean i think u did not get my question ,i have six images in a single figure window,i have uses subplot function ,i want to write it into a file ,please help

[Sean de Wolski]

see clarification.

[Titus Edelhofer]

Hi Pat, please describe more detailed, what you want: do you want to save your 6 subplots to 6 different image files?
