Re: [Scilab-users] Scilab problem?
Hello,
I used [free, total]=getmemory() before and after each plot and there is still
some memory left after the last plot.
I'm not sure this is related because I learned some years ago that for plotting
with a lot of data it is important to increase the Java Heap Memory. If I
understand correctly the memory I display with the command above is the
internal SCILAB memory. Not related to the plotting issue.
It seems I'm somehow locked because I cannot increase the Java Heap Memory
because of the problem you mentioned!
Will this issue be solved in the 5.5 version?

Hello,
I'm using Scilab 5.4.1 on Win 7 64 bit and have a problem with the following
script (simplified script).
stacksize('max')
Maximum=5e6;
dt=1/Maximum;
t=0:dt:1;
y=sin(2*%pi*50*t);
f0=scf(0);
clf;
plot(t,y);
f1=scf(1);
clf;
plot(t,y);
f2=scf(2);
clf;
plot(t,y);
With the standard Java Heap Memory (256MB) the first and second plots are
ok. Nothing is drawn in the third plot.
I thought it may help to increase the Java Heap Memory.
You may use
[free, total]=getmemory()
before each plot in order to check the decrease of available memory
If I increase the Java Heap Memory to 512 MB I get immediately the
following error message on the console:
This bug has been reported here: http://bugzilla.scilab.org/12411 :
Critical error with stacksize(max) after increasing the Java heap memory

[Scilab-users] bug in scilab 5.41 and 5.5beta? 64bit versions
I have been using scilab for many years.
today I downloaded for my new computer scilab 5.41(64bit) and got
afterwards on the first start
an error message like the ones further down
on the version 5.5beta(64bit) there happens the same sort of thing
on both versions the control bar file, edititing ... does not work
i.e. no response on klick
for version 5.41

Re: [Scilab-users] GIF with transparent color
Le 04/11/2013 17:01, SCHULZ Wolfgang a écrit : Hello, I'm creating contour plots and it would be nice to have certain regions (colors) of a GIF file transparent. By the way, as far as i know, GIF and PNG allow to define only /one/ transparent color. So, if you want several regions of distinct colors of the same plot being transparent, PNG and GIF would not allow that. I don't know any other common image formats able to do that. If you are looking for transparency of the foreground in order to see the figure's background instead of the image's one, tricks given by Christophe and Antoine will certainly work. In the end, you may have a look at /help pixel_drawing_mode/ . This feature for instance used to help plotting stacked objects without hidding stacked parts. But Scilab 5.4 has killed it : http://bugzilla.scilab.org/show_bug.cgi?id=12017 Best regards Samuel ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
