- If you do not specify an extension, then saveas saves the figure to a FIG-file.
why does whiteness show up ? !

I saved an image in my file using "saveas" and I have used those instructions
DirectoryPath =('C:\Users\Mayssa\Desktop\pfe\Matlab\interface');
whereToStore=fullfile(DirectoryPath,a);
saveas(gcf, whereToStore);
But when I try to read it (with imread) it shows up on a a white background, how can I get rid of it ? :(

From the saveas documentation:
Instead of imread, see if openfig works.

Try this:
figure(1)
plot(-10:10, exp(-([-10:10]/5).^2))
saveas(gcf, '#TestSAVEAS_01.png');
figure(2)
plot(-10:10, 1-exp(-([-10:10]/5).^2))
saveas(gcf, '#TestSAVEAS_02.png');
A = imread('#TestSAVEAS_01.png');
B = imread('#TestSAVEAS_02.png');
figure(2)
image(uint8((double(A)/2 + double(B)/2)))
hold on
hold off
title('Retrieved & Combined Images')
delete('#TestSAVEAS_01.png')
delete('#TestSAVEAS_02.png')
