Follow-up Comment #11, bug #31884 (project octave):
Hi, Ben.
(Sorry for my late reply. I got a cold and was in bed.)
After pulling your changeset,
The following code occurs flicker and changing size each time through the
loop.
%test1
figure(1);
for f=1:20
image(floor(255*rand(32,64)));
colormap(gray(256));
axis image
axis off
drawnow
eval(sprintf('print -dpng /tmp/%03d.png',f))
end
-----------------------------
when i remove "drawnow", it redraws the figure window each time through the
loop.
it does not occur flicker and changing size.
%test2
figure(1);
for f=1:20
image(floor(255*rand(32,64)));
colormap(gray(256));
axis image
axis off
eval(sprintf('print -dpng /tmp/%03d.png',f))
end
-----------------------------
when i remove "print" , it works well.
%test3
figure(1);
for f=1:20
image(floor(255*rand(32,64)));
colormap(gray(256));
axis image
axis off
drawnow
end
--------------------------------
when i remove "print" and "drawnow" , it shows the last image only.
%test4
figure(1);
for f=1:20
image(floor(255*rand(32,64)));
colormap(gray(256));
axis image
axis off
end
--------------------------------
when i replace "drawnow" to "pasue(1)", it occurs flicker and changing size
each time through the loop.
"pause(1)" does not work. it finished soon.
%test5
figure(1);
for f=1:20
image(floor(255*rand(32,64)));
colormap(gray(256));
axis image
axis off
pause(1)
eval(sprintf('print -dpng /tmp/%03d.png',f))
end
--------------------------------
when i replace "drawnow" to "pasue(1)", and remove "print". it redraws the
figure window each time through the loop.
"pause(1)" works well. it takes about 20 sec.
%test6
figure(1);
for f=1:20
image(floor(255*rand(32,64)));
colormap(gray(256));
axis image
axis off
pause(1)
end
