hold off
clf;

%
% Draw a box using the patch facility
%
x = [.2 .8 .8 .2];
y = [.2 .2 .8 .8];
patch(x, y, [.4 .8 1]);

%
% Allow additional drawing to plot
%
hold on

%
% Draw another patch on top of the first
%
x = [.3 .7 .7 .3];
y = [.3 .3 .7 .7];
patch(x, y, [0 1 1]);

%
% Now draw text anywhere within the patch area, for at least
% 57 times to reproduce the bug
%
for i = 1:57
  text(.5, .5, 'x');
end;

%
% Clean up
%
axis([0 1 0 1]);
hold off

%
% Note that the Octave plot displays properly.  It is when
% saved to a file that the plot is messed up
%
print -djpg out2.jpg
print -dpdf out2.pdf
print -dpng out2.png

%
% Look at the output files 'out2.jpg', 'out2.pdf', and
% 'out2.png'.  The patch box is displayed incorrectly.
% However, the patch box on the original Octave plot is
% displayed correctly.
