Extracting frames from Quicktime movies?
by Dinu Gherman Feb. 20, 2004

Feb. 20, 2004

Hi, does anybody have a few Python lines of code for extracting a frame from a Quicktime movie? I'm actually only interested in the first frame, but a more general solution would also be nice.

How do you debug Cocoa GUI with PyObjC applications
by Vincent Marchetti Feb. 19, 2004

Feb. 19, 2004

I'm asking how people trace/debug/watch Python applications that use a Cocoa based GUI via PyObjC. I've got the PyObjC examples set, and as I pretty much expected they crash outright when run from PythonIDE (conflicting event loops I imagine). When I fiddle and try to run from a Terminal window using "pythonw mainApp.py" I get an error message complaining about lack of an Info.plist file, and finally when using the method of building a clickable application using bundlebuilder the examples run, but there is no obvious way to trace through the execution except by throwing off a lot of alert windows. Any suggestions or example files would be welcome! Thanks Vince Marchetti

Folks, is there a record somewhere in Python of which *.pth files were read to fill sys.path? Cheers, Erik van Blokland

Python package directory confusion
by Christopher Fonnesbeck Feb. 19, 2004

Feb. 19, 2004

It seems as though my python installation on 10.3 is messed up. After installing some packages, python is unable to see some packages that are clearly present (e.g. Numeric). Upon inspection, I see that I have 2 package directories, /System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/ site-packages/ and /Library/Python/2.3, the former being empty. Why are there 2 locations, and why is MacPython using the empty one? More importantly, how can I avoid this problem in the future? Thanks, C. -- Christopher J.

Concatenate PDFS's with python
by Tim Conner Feb. 19, 2004

Feb. 19, 2004

I'm looking for some print house type solutions that use coregraphics/quartz and python to manipulate images, eps's, and pdfs. To get started on this quest it would be nice if someone could point me to examples or write a quick sub-routine that would take 2 pdfs and combine them into 1, 2-page pdf. I just need a stepping stone to get me rolling. I also need the same thing for jpegs, but once I see a pdf example, I should hope I can handle that on my own. Thanks, Tim

bundlebuilder tutorial available
by Russell E. Owen Feb. 18, 2004

Feb. 18, 2004

I have made a tutorial for bundlebuilder available at <http://www.astro.washington.edu/owen/BuildPythonMacApp.html>. It does not mention Bob Ippolito's nifty-sounding bundlebuilder2 preview as I wasn't sure how widely that should be advertised. Comments and corrections welcome, as always. I could try to put this on the FAQ wiki if folks think it worthwhile. Also, my instructions for installing Tkinter have been updated. They now include instructions for Aqua Tkinter--nearly trivial, of course--and also for X11 Tkinter <http://www.astro.washington.edu/owen/PythonOnMacOSX.html>. -- Russell

Menus from pyobjc
by Dethe Elza Feb. 17, 2004

Feb. 17, 2004

Hi folks, I'm working on a demo app using PyObjC for the UI, but without using a .nib file. I'm running it using pythonw and mostly it works OK, but I'm having trouble with menus. It defaults to a Python menu, but when I query the app.mainMenu() it reports None, when I use app.setMainMenu_(mymenu) at only the Python menu shows up. Further symptoms: * When I click on the menubar my new menus (submenus of mymenu) show up, but are disabled, even if I explicitly enable them or provide appropriate targets/actions. * Even though I've set the main menu, the Python menu still shows up, but is empty. Any suggestions? I can provide some example code, but it's kind of jumbled right now. If you're wondering what the point is, I'm hoping to work towards something like Renaissance/XUL (i.e., driving the UI from XML rather than from .nibs). At this point I'm just trying to pull together a proof-of-concept to see if it can be done.

My apologies, you were correct. I want to input multiple pdfs and have them combine. I'm sure the command is in there... we'll see how I do and I'll post the results here.

I've looked at those examples and they show how to create a pdf, not manipulate an existing one. They are good py examples, but not for the topic I'm looking for. :) Thanks, Tim On Tuesday, February 17, 2004, at 09:02AM, Bob Ippolito <bob(a)redivi.com> wrote >On Feb 17, 2004, at 9:33 AM, Tim Conner wrote: > >> I'm looking for some print house type solutions that use >> coregraphics/quartz and python to manipulate images, eps's, and pdfs. >> To get started on this quest it would be nice if someone could point >> me to examples or write a quick sub-routine that would take 2 pdfs and >> combine them into 1, 2-page pdf.
