save images in a new folder

Hi,

I am using the below subroutine inside for loop to save images during every itertaion. Here, I would like to save the images in new folder. Please help me with this...

if (f>=1) && (f<=9)
    saveas(gcf, sprintf('S0000%d', f), 'bmp')
    elseif (f>=10) && (f<=99)
         saveas(gcf, sprintf('S000%d', f), 'bmp');
    elseif (f>=100) && (f<=999)
          saveas(gcf, sprintf('S00%d', f), 'bmp');
    else
         saveas(gcf, sprintf('S0%d', f), 'bmp');
 end

Hi,

Tried as follows, bur it's not saving any images

folder = 'D:\CH\new\';
for f = 1:1:2
    if (f>=1) && (f<=9)
        fname_strt = 'B0000' ;
    elseif (f>=10) && (f<=99)
        fname_strt='B000';
    elseif (f>=100) && (f<=999)
        fname_strt='B00';
    else
        fname_strt='B0';
    end
    fname_end = num2str(f);
    fname = strcat(fname_strt,fname_end,'.im7');
    I=loadvec(fname);
    x=(I.x);
    y=(I.y);
    h = figure (2);
    G= imagesc(x,y,(I.w'));
    ax=gca;
    %G.AlphaData = 0.9;
    colormap(bone);
    set(gca, 'YDir','normal')
    axis equal;
    thisBaseFileName = sprintf('S%4.5d.png', f);
	fullFileName = fullfile(thisBaseFileName);
	fprintf('Saving %s\n', fullFileName);
  %clf
  %DISP off;
end

saveas(gcf, fullFileName)

Hi,

Thanks, Actually, I figured that, added saveas(gcf, fullFileName). Now, it saves images, but it saves in the same folder where i am reading the input file

for example if i am reading the file from 'D:\CH\', the processed file should save inside 'D:\CH\new\'....

[Mario Malic]

prefix = '\\new\\'; 
thisBaseFileName = sprintf('%sS%4.5d.png',prefix, f);

Have two folders:

inputFolder = 'D:\CH\';
outputFolder = 'D:\CH\new\';
if ~isfolder(outputFolder)
    mkdir(outputFolder);
end

Then in the loop

fname  = fullfile(inputFolder, fname); % Create full input filename.
thisBaseFileName = sprintf('S%4.5d.png', f); % Base output file name.
fullFileName = fullfile(outputFolder, thisBaseFileName); % Create full output filename in different folder.

Not sure why you removed the folder from my call to fullfile() in my answer. You should not have done that. fullfile() needs both a folder and a base file name.

Thanks it worked perfectly..

Furthermore, regarding my previous query on "having two colorbars in the contours for the images read in .im7 format". I have sent the .im7 files and loadvec function as per your request. Is .im7 readable now ???

Answer 1

[Image Analyst]

Do it this way:

folder = pwd % Wherever you want...
for k = 1 : 1234
	thisBaseFileName = sprintf('S%4.4d.png', k);
	fullFileName = fullfile(thisBaseFileName);
	fprintf('Saving %s\n', fullFileName);
% 	saveas() of exportgraphics()
end

Answer 2

[Mario Malic]

saveas(gcf, sprintf('/folder/S0000%d.bmp', f))

Is 'f' here represents the folder destination ??

[Mario Malic]

No, /folder/ is, but use Image Analyst's solution, it's much better than what you have.
