Hello All,
I would like to convert (file.fig) to (file.jpg) in the same time (each file contents 5 plots) to reduce the time. I used this code to convert one file.fig:
figs = openfig('Fall_ABS.fig');
for K = 1 : length(figs)
filename = sprintf('figure_%02d.jpg', K);
saveas(figs(K), filename);
end
close all
How can I update this code to convert two files.
Thanks in advance,
Riyadh

put all figures to translate to .jpg in a same folder
put all .fig in same folder
cd 'folder_figures'
get in the folder
system('dir /o:n /b > list.txt')
build list
fid=fopen('list.txt')
s1=textscan(fid,'%s')
fclose(fid)
measure how many figures
[sz1 sz2]=size(s1{1})
load all figures in workspace
h0=[];
for k=1:1:sz1
if regexp(cell2mat(s1{1}(k)),'.fig')
s=openfig(cell2mat(s1{1}(k)));
h0=[h0 s];
end;
end;
save figures in same file
savefig(h0,'all_figures.fig')
Riyahd, do the figure handles have to be in separate variables, or is it ok that all such handles are in a 1x10 vector of handles?

Using system('dir /o:n /b > list.txt') instead of Matlab's dir command is much slower and prone to errors. The current folder is polluted by a "list.txt" file and if several codes run simultaneously (e.g. in timer oder GUI callbacks) theses files can interfere.

folder = cd; % Set accordingly
figs = dir(fullfile(folder, '*.fig'));
for K = 1:length(figs)
FigH = openfig(fullfile(folder, figs(K).name));
filename = fullfile(folder, sprintf('figure_%02d.jpg', K));
saveas(FigH, filename);
close(FigH);
end

Do you mean "folder = cd"? This means that the variable "folder" should be set to the folder your images are stored in. Using absolute paths is safer than relying on the current folder.
