I would use Sage to zip up all the files into one file:

from subprocess import call
call("zip -r all.zip %s/*"%DATA,shell=True)

Thank you! that's it!! :) And if I want to erase that file? where is it saved? And what is the command to delete it?

Maybe I didn't say it clearly, if so I apologize. I want to save all the files of the data folder of one worksheet in the host computer (windows), not all the worksheets. I'm quite new with this featurings in Sage 5.0, I don't know how to exit of the GUI :S. If there's a way to do it in the console it would be fine if you were more specific :S. Sorry for that, I'm a new user.

Hi! I'm trying to download all the data folder of a worksheet. I see the GUI permits you to download it one single file at once. I have many files (about 2000 files), and I'm unable to download all the folder at once. I'm using VirtualBox at Windows and it's Sage 5.0 version.

How can I do it?

Thank you! :)

I wanted to aswer just ":)", but I need 10 chararcters :D

I see. Well, first off, the things in your saved are not actually graphics file, but Tachyon scenes. Secondly, we can access things in the notebook via the DATA variable. Borrowing some ideas from the thread mentioned in the other post:

for i in range(len(saved)):
    saved[i].save(filename=DATA+'mypic%d.png'%i)

os.system('cd '+DATA+'; convert -delay %s -loop %s *.png "Done.gif"'%(int(100),int(2)))
os.system('ls '+DATA)

This shows that the Done.gif is there. If you then go to the "Data..." menu and choose it, you will see it and be able to download it. That's not ideal, but a lot better than nothing.

Naturally, this all assumes you have animate working properly (because that requires the convert command we are using here). Probably I should also use sage-native-execute but I don't really understand that.

To the guy who will see this in the future (he could be me tomorrow): that funtion is ok if len(saved) < 10, if it's bigger the names of the should have more digits.

I thought animate function had more freedom to choose the types :(

Thank you!!! That's it! I wanted something simple, because I can only use the notebook (I cannot modify the system). Thank you very much

Thank you. I had already seen that answer. But I think, that what I want to do is too simple to attack it with a powerfull tool (that I don't know how to use). I mean, animate function should be enough to join a couple of photgrams... or not?

Hello!

I'm trying to create a 3d animations, frame per frame. I've discovered that tachyon plotter is very usefull to create images. But after that, I'm unable to make it as animation.

For example, I have copied a code and generate some scenes with tachyon with this:

saved = []
for j in srange(-0.9,1,0.3):
   t = Tachyon(xres=512,yres=512, camera_center=(3,0.3,0))
   t.light((4,3,2), 0.2, (1,1,1))
   t.texture('t0', ambient=0.1, diffuse=0.9, specular=0.5, opacity=1.0, color=(1.0,0,0))
   t.texture('t1', ambient=0.1, diffuse=0.9, specular=0.3, opacity=1.0, color=(0,1.0,0))
   t.texture('t2', ambient=0.2,diffuse=0.7, specular=0.5, opacity=0.7, color=(0,0,1.0))
   k=0
   for i in srange(-1,j,0.05):
      k += 1
      t.sphere((i,i^2-0.5,i^3), 0.1, 't%s'%(k%3))
   saved.append(t)

In "saved" array I have all the png of the animation I want to do, and I can view it with saved[i].show().

I tried to unite all the frames with the command animate:

animate(saved[i].show() for i in range(0,len(saved)))

But it didn't work. What other alternatives do I have? (without using ffmpeg)

Thank you!
