LyX ⇒ Have anyone used "impressive" for pdf presentations?

[lyxer]

Hi

I have created a presentation in Lyx with the beamer class, and wanted
to add some effects to the pdf presentation using “impressive”.

http://impressive.sourceforge.net/manual.php

I think I have all the necessary files:

impressive
Python
Pygame-1.9
PyOpenGL-3.0.1
xpdf-3.02

I just don’t know how to start using it.

For reference, I'm using Mac OSX.

Appreciate any help.

Impressive is a command line tool written in Python. On the page you linked you will find clear descriptions under »General Installation« how to use it. Read the entire manually carefully and you will know how to handle it (on which platform ever).

Still can't get it to work.

Under Installation it says just type : impressive.py demo.pdf
However, it doesn't say where to type this. Anyways, whenever I click on the file "impressive.py", I get two windows:

The first one is {impressive.py window} full of code.
The second one is {python shell}.
I tried typing "impressive.py demo.pdf" but always got syntax error.

I tried another method by right-clicking on "impressive.py" and
then choosing Python Launcher 2.7 or 2.6.5. This gave me a Terminal window
with the command line : ... ~macpro$. I typed the command again here but I got a message saying [command not found].

This is just a guess, but try something like this:

Open a terminal. At the prompt ~@macpro$ or whatever type in:

Code: Select all

export PATH=$PATH:/path/to/impressive

but replace /path/to/impressive with the directory where impressive.py is found. E.g., if it is your home folder, use /Users/yourname/ or whatever.

Then:

Code: Select all

cd "/path/to/pdffile/"

replace /path/to/pdffile with the directory where your PDF file is.

then:

Code: Select all

impressive.py demo.pdf

should work.

Thanks,

I got the following error:

" Oops! Cannot load necessary modules: No module named OpenGL.GL
To use Impressive, you need to install the following Python modules:
- PyOpenGL [python-opengl] http://pyopengl.sourceforge.net/
- PyGame [python-pygame] http://www.pygame.org/
- PIL [python-imaging] http://www.pythonware.com/products/pil/
- PyWin32 (OPTIONAL, Win32) http://starship.python.net/crew/mhammond/win32/
Additionally, please be sure to have pdftoppm or GhostScript installed if you
intend to use PDF input. "

I have the first three programs, and since I'm using a mac I don't need the
last one. I'm surprised because the PyOpenGL has an "OpenGL" folder inside it. Also, the PIL is inside the "imaging" folder. So, it seems everything is
there.

Not sure what the problem !!
