hello all,
when i generate a 3-D plot plot withe following code:

k = 5;
n = 2^k-1;
[x,y,z] = sphere(n);
c = hadamard(2^k);
surf(x,y,z,c);
colormap(F.colormap);

it genrates a 3-d plot without any rectangular box around the figure.
but if i write the following code to save the figure as some format,

k = 5;
n = 2^k-1;
[x,y,z] = sphere(n);
c = hadamard(2^k);
surf(x,y,z,c);
F = getframe(gcf);
image(F.cdata);
colormap(F.colormap);
saveas(gcf,'name','pdf');


it creates a rectangular outer box.Can u pls help me,how to remove the outer box.image(F.cdata) creats the rectangular box. pls help me...thanx in advance.
