saving all open figures in script as .png file in a folder

working with image processing toolbox and trying to save all the figures as .png or .jpeg format in a specific folder using the code below:

FolderName = ('G:\Image proccessing\test'); % using my directory

FigList = findobj(allchild(0), 'flat', 'Type', 'figure');

for iFig = 1:length(FigList)

FigHandle = FigList(iFig);

FigName = num2str(get(FigHandle, 'Number'));

set(0, 'CurrentFigure', FigHandle);

saveas(FigHandle, strcat(FigName, '.png'));

end

there is no error but no image is saved.

It may be that the .png files are being saved in the current working directory (because FolderName (G:\Image proccessing\test) is not being used).

Try this instead:

FolderName = ('G:\Image proccessing\test');   % using my directory
FigList = findobj(allchild(0), 'flat', 'Type', 'figure');
for iFig = 1:length(FigList)
  FigHandle = FigList(iFig);
  FigName   = num2str(get(FigHandle, 'Number'));
  set(0, 'CurrentFigure', FigHandle);
%   saveas(FigHandle, strcat(FigName, '.png'));
  saveas(FigHandle, fullfile(FolderName,strcat(FigName, '.png'))); % specify the full path
end

Verify that FigList contains all your figures, and possibly use the debugging utilities to figure out where the code is going wrong.
