how to transfer *.svg to *.gif or jepg?

Hello,

Your question is not clear at all. If you want an answer to your problem, you should explain it in more details as we are not inside your computer!

If you want to save an image from Sage in a specific format you can do:

sage: G = circle( (0,0), 2)
sage: ...   # add more plot

and then

sage: G.save('my_picture.eps')

or

sage: G.save('my_picture.png')

There are a lot of supported format.

Now, if you want to convert an image from eps to png, or jpeg to gif you can use the convert tool from image magick.
