FontSize for the image's legend

I have the following code:
X = 0:pi/100:0.25*pi;
Y1 = sin(X);
Y2 = cos(X);
Y3 = tan(X);
fh = figure('toolbar','none','menubar','none','Units','characters');
Pan1 = uipanel(fh,'Units','normalized','Position',[0 0 0.5 1],'title',...
'Panel1');
Pan2 = uipanel(fh,'Units','normalized','Position',[0.5 0 0.5 1],'title',...
'Panel2');
haxes = axes('Parent',Pan2,'Units', 'normalized','Position',...
[0.125 0.1 0.75 0.75]);
hplot = plot(haxes,X,Y1,X,Y2,X,Y3);
xlabel(haxes,'Time (second)');
ylabel(haxes,'Amplitude (meter)');
title(haxes,'Trigonometric functions');
Ley = {'Sine function','Cosine function','Tangent function'}; %# legend's strings values
legend(haxes,Ley,'Location','SouthOutside');
[FileName,PathName,FilterIndex] = uiputfile('*.bmp;*.png;*.jpg;*.tif','Save as');
ftmp = figure('Menu','none','Toolbar','none','Units','normalized',...
'Position',[-1000 -1000 1 1]);
set(gcf,'PaperPositionMode','auto');
set(gcf,'InvertHardcopy','off');
new_axes = copyobj(haxes, ftmp);
legend(new_axes,Ley,'Location','SouthOutside','FontSize',8);
set(new_axes,'Units','normalized','Position',[0.1 0.1 0.8 0.8]);
fmtgraf = {'-dbmp','-dpng','-djpeg','-dtiff'};
fmt = fmtgraf{FilterIndex};
print(ftmp,fmt,FileName,'-r0');
delete(ftmp);
delete(fh);
As seen in the code, the command line
legend(new_axes,Ley,'Location','SouthOutside','FontSize',8);
is run before the command line
set(new_axes,'Units','normalized','Position',[0.1 0.1 0.8 0.8]);
Because of it, the image appears cutted by its low part as seen here (independently of the existence or no existence of the property/value 'FontSize')
If the command line
legend(new_axes,Ley,'Location','SouthOutside','FontSize',8);
is run after the command line
set(new_axes,'Units','normalized','Position',[0.1 0.1 0.8 0.8]);
now the image is cutted by its low part but in this case it is not seen neither the xlabel text nor the legend box (as seen here)
If `'FontSize',8` is suppressed, all is Ok. How can I fix this if I want that the legend to have a lesser size?

"the image file does not appear drawn correctly" is too vague for us to work with.

If I understand correctly. You set the legend to be outside the figure, then set its text size, and then rescale the axis.
legend(haxes,Ley,'Location','SouthOutside');
legend(new_axes,Ley,'Location','SouthOutside','FontSize',8);
set(new_axes,'Units','normalized','Position',[0.1 0.1 0.8 0.8]);
You are now upset that 0.1 normalized units does not provide enough space for a legend with 8 point font. There simply is not enough space to position everything optimally. What do you want MATLAB to do? Have you tried
set(new_axes,'Units','normalized','Position',[0.4 0.4 0.2 0.2]);
You might want to try one of the legend function on the FEX. Maybe http://blogs.mathworks.com/pick/2011/02/11/create-multi-column-plot-legends/

I do not see any problems using Matlab 2009a.
The posted code seems to be more complicated than necessary. Are the UIPANELs required to reproduce the problem?
