writing an image into a new folder

I have a code which was given by image analyser

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 want it to be saved in a folder named 'new',because i will have 100 figure windows,in which each figure window contains 8 subplotted images

Maybe you are seeking for this sample code :

clear; clc;

I = imread('peppers.png');
J = imread('onion.png');
K = imread('pears.png');
Img = {I J K};
for cnt1 = 1 : length(Img)
    figure,    
    subplot(2,3,1),imshow(Img{cnt1});
    subplot(2,3,2),imshow(rgb2gray(Img{cnt1}));
    subplot(2,3,3),imshow(im2bw(Img{cnt1}));
    filename = strcat('picture_of_figure',num2str(cnt1));
    print('-dbmp256',filename);
end

maybe the OP was - but they would learn more by working out the actual code themselves...

Chandra even in your code i could not find a folder name

this is what i want

a folder named "new"

want to save all those figure windows in it

[Chandra Kurniawan]

Then you need to specify your path folder

Eq : filename = strcat('E:\picture_of_figure',num2str(cnt1));

In your case is :

filename = strcat(pwd,'\New\picture_of_figure',num2str(cnt1));

If you have a folder named 'New' in your active directory.

[Robert Cumming]

using fullfile ( folder, filename ) is better than strcat.

help saveas

e.g.

SAVEAS(H,fullfile ( 'new', 'FILENAME' ),'FORMAT')

[Pat]

thanks robert ,i have a for loop ,will those 100 images will be saved in that folder

please tell what that file name refers to

[Robert Cumming]

filename is the filename of your image....

e.g. sprintf ( 'image_%i', ii );

where ii is your loop...

[Pat]

Robert am little bit confused in file name ,i have only subplotted image ,from where i have to get file name

for ex

figure,

subplot(161),imshow(I1)

subplot(162),imshow(I2)

subplot(163),imshow(I3)

subplot(164),imshow(I4)

subplot(165),imshow(I5)

subplot(166),imshow(I6)

where I1 to I6 are the images after performing 6 different operations,please tell how to save this in folder,my folder name is 'new'.this is for one image performing 6 operaitons,i have 100 images ,i have to perform for all those,finally i will have 100 figure window of 6 subplotted images,i want to save all those to a folder named 'new'

please help

[Robert Cumming]

the filename is your choice. Have you looked at saveas? See the following code as an example you should be able to work it out from there...

h=figure

subplot(2,3,2); plot ( magic(100) );

saveas ( h, 'YOURFILENAME', 'bmp' )

[Pat]

Robert i have seen save as in help ,but its for writing one figure window,but i want to write in folder as i said,where that folder will contain 100 figure window,as per your last code,i cant see the folder name

[Robert Cumming]

I have given you all the information you need to workout the code yourself - I strongly encourage you to do that as you will learn more that way...
