A > Google search doesn't turn up anything useful (or I'm not doing it > right). Among other reasons, I updated PyFT to handle that gracefully. Because of unavailability of web space for some time, I had only semi-released it. It is now at http://starship.python.net/crew/kernr/source/PyFT-0.65.tar.gz It has a nice class-based wrapper around the nasty function calls. One does essentially the following: >>> f = Font('times', size=12, bold=0, italic=1) >>> rend = BaseRenderer(resolution=(96,96), aa=1) >>> rend.drawString(PIL_image, 'FooBar', x_pos, y_pos, f) and 'FooBar' will be rendered in 12-point, italic Times New Roman onto the PIL Image instance PIL_Image with the appropriate alpha mask. Just set up the font locations correctly at the beginning of the PyFT.py file. I have given up maintenance of PyFT since I've moved onto other things. Steve Alexander has offered to take it over. Of course, someone (not me) should write a new PyFT from scratch to wrap FreeType2. -- Robert Kern kern(a)caltech.edu "In the fields of hell where the grass grows high Are the graves of dreams allowed to die." -- Richard Harter

zope's acquisition inheritance
by Wostenberg Jan. 31, 2002

Jan. 31, 2002

This Smalltalker has been studying Zope, the Opensourced python product for internet deployment (see http://www.zope.org), to learn. It has an unusual model of interitance called acquisition, which blends class heiarchy with containment. Read http://www.zope.org/Members/Amos/WhatIsAcquisition for introduction. Basically "objects automatically gather. services from their containers.". Everything is potentially a collector-class, and if I drop objects into a collection, they inherit behavior from the container. Weird, but somehow natural in this Web environment which organises content around a tree-structured containment plan. Anybody heard of acquisition outside Zope, or is it a new contribution to OO modelling? -Alan

Circular references and python
by Jason Stokes Jan. 27, 2002

Jan. 27, 2002

Well, my adventures with the Python language are moving along. One thing that worries me is the lack of garbage collection in Python; the application I'm thinking of using Python for demands many data structures that use circular references, but Python only implements a reference counting scheme in the way of memory management. How do I use such data structures in Python?

affects on extended modules
by Curtis Jensen Jan. 3, 2002

Jan. 3, 2002

We have created a python interface to some core libraries of our own making. We also have a C interface to these same libraries. However, the the python interface seems to affect the speed of the extended libraries. ie. some library routines have their own benchmark code, and the time of exection from the start of the library routine to the end of the library routine (not including any python code execution), takes longer than it's C counterpart. Note, all data memory in Python is allocated using Numeric to allocate memory for arrays. All data memory in the C counterpart is allocated using basic array constructs using alloc. We are unsure of why there is a performance difference. We only have some speculation. Our best guess is that the memory allocated in Python is causing cache faults and thus incurring some overhead. If anyone else has any ideas, we would appreciate any input. Thanks. -- Curtis Jensen cjensen(a)bioeng.ucsd.edu http://www-bioeng.ucsd.edu/~cjensen/ FAX (425) 740-1451

How much is set in stone?
by Jive Dadson Dec. 30, 2001

Dec. 30, 2001

I'm a newbie at Python, but I've been up to my ears in it for the last couple of days. -- Considering using it for a scripting language for a product at work. I'm very impressed with the system. Of course there are things I would like to change. :-) So the question is, how much is set in stone at this point? Is the definition of 2.x now the law of the land, or can we still make suggestions?

[help] Driving Visual Studio From Python
by Michael Schneider Dec. 14, 2001

Dec. 14, 2001

Hello All, I am an old unix developer finally moving to Windows Visual C++. I have been using python on Unix since 96, and have been really happy with python as a scripting/tools language. I need to drive visual studio to create projects, add configurations, and add files to projects. The COM extensions make it look like it is possible to do this, but I am having trouble getting it going. I have ran makepy and added the visual studio type libs. I copied the following code from a post ----------------------------------------- import win32com.client app = win32com.client.Dispatch( 'MSDev.Application') wnd = app.ActiveWindow if wnd.Type == 'Text': print wnd.Selection app = None ------------------------------------------ This prints on the selected test. I can't seem to get the syntax to obtain and print out project properties, or to add a project Could someone help my out by giving me the python code to try to get this to go, I am missing something very basic here. Thanks Mike PS. I added the MSDEV links to the visual studio docs ++++++++++++++++++ DeveStudio Link to add project http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcug98/htm… Link to Visual Studio Application Object http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcug98/htm…
