[Visualpython-users] Placing Graphics Output on a Printer

How do I print the graphic material on my printer, or capture it to a file?

Depends on your computer platform. For example, on Windows you can make the 
window active and press Alt-Screen, then paste into Word and print.

It's possible that PIL (Python Imaging Library) has routines for capturing from 
the screen; not sure.

In the contributed section of vpython.org is a routine for exporting a scene to 
POV-Ray, a multiplatform free ray-tracer which generates higher-quality images 
than Visual can do in real time.

Thanks. I found some hints in the FAQ. I have SnagIt, so that will 
probably suffice. More questions.

How do I find other attributes for various objects like curve, sphere, 
etc.? For example, is there an edge attribute for sphere, so that if I 
make it completely transparent, the outline can still be seen?  An 
outline. If so, can its thickness be changed? Is it possible to use 
Greek letters in Label? Is there a hemisphere object? Maybe it's an 
attribute of sphere? I guess ring is for circles? Are there arcs 
somewhere with arrows on each end for putting text between the arrows? 
Just plain arcs (part of a circle) or solid sections of a sphere 
(surface section area extending down to the center of the sphere)? Can I 
put an arrow on a graph? That is, suppose I wanted to show an x-y 
coordinate system with a drawn vector on it.

It doesn't seem as though Windows (choice) works properly on 
<file:///C:/Python25/Lib/site-packages/visual/docs/visual/cylinder.html>. 
It acts just like Windows/Events/Files.

What you see in the documentation is all you get. If you don't find what you 
want, it's because it doesn't exist.

As mentioned in the documentation, you can use full Python Unicode strings in a 
label.

The documentation for graphs says this:

"Every gdisplay has the attribute display, so you can place additional labels or 
manipulate the graphing window. The only objects that you can place in the 
graphing window are labels, curves, faces, and points."

Can you say in more detail how you find a broken link in the documentation? I 
don't find the broken link you report.

I thought I had fixed the link in my e-mail. That's incorrect. Here's
the right one.
<file:///C:/Python25/Lib/site-packages/visual/docs/visual/display.html>.
The three pulldown menus show:
3D objects, Working with objects and Windows/Events/Files. If I select
in the last one, Windows, nothing changes. It continues to show a
description for "Controlling One or More Visual Display Windows". If I
got Mouse Drag, that shows in the description, but the third menu
continues to show "Controlling One or More Visual Display Windows". I
got it. They all work that way. The three menus always show the first
item. I think I'm used to seeing pull downs that actually advance to the
item selected. There is no problem.
