[Visualpython-users] Advice for experienced programmers

[Bruce S. <Bru...@nc...>]

 From time to time I've seen colleagues with extensive programming 
experience but who are new to Python trip over some aspects of Python 
that are different and unexpected. In response I've written a note about 
what I perceive to be the most common traps and posted the note on the 
home page of vpython.org (labeled "Python for experienced programmers").

If you see some other issues that should be included in this summary, 
I'd be grateful to have them pointed out.

And if you think this might be useful elsewhere within the Python 
community, feel free to point people to it or copy it to other places.

Thanks.

Can one save vpython screen images within python, [i.e.not using prtscrn]?

Jose adviced you tu use PIL but i think it depends on which OS you would li=
ke=20
to save an image from vpython screen.

I tried PIL under linux but it seems that it is working really better under=
=20
windows.

I'm using something not really satisfying but it is working ... i really th=
ink=20
there are some ways to improve it, because in that code, you must specify t=
he=20
position and size of the area you would like to grab. It is more a script t=
o=20
take screenshots.

import gtk, gc

width =3D 640
height =3D 480
x =3D 1
y =3D 1
filename =3D 'test.png'
screenshot =3D gtk.gdk.Pixbuf.get_from_drawable(
            gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB, True, 8, width, height),
            gtk.gdk.get_default_root_window(),
            gtk.gdk.colormap_get_system(),
            x, y, 0, 0, width, height)
screenshot.save(filename, 'png')
del screenshot
gc.collect()

Re: [Visualpython-users] saving vpython images?

I think that the PIL image library has a functionality to capture the 
screen, indeed specifiing a box.

Thus using the window coordinates you can save the image indeed in a lot of 
formats.

Hope this works and helps.

I really hope so, please let me know if this works, I have not tried this.
