ANN: ClientCookie 0.3.4b
by jjl＠pobox.com 30 Apr '03

30 Apr '03

http://wwwsearch.sourceforge.net/ClientCookie/ Changes since 0.3.1b: * MSIECookies now works. Thanks to Eric Woudenberg for a patch and Johnny Lee (no relation) for some help. * Small change to bugfixed HTTPRedirectHandler: 301 from a POST is now allowed, and redirected as a GET (see Python SF bug #549151). * Minor documentation fixes. * All tests now use unittest. * Fixed 1.5.2-compatibility bugs (revealed by existing tests -- seem to have been missed with old testing system for some unknown reason). Requires Python >= 1.5.2. urllib2 is recommended. 1.5.2-compatible urllib2 / urllib is at http://wwwsearch.sourceforge.net/ ClientCookie is a Python module for handling HTTP cookies on the client side, useful for accessing web sites that require cookies to be set and then returned later. It also provides some other (optional) useful stuff: HTTP-EQUIV handling, zero-time Refresh handling, and lazily-seekable responses. It has developed from a port of Gisle Aas' Perl module HTTP::Cookies, from the libwww-perl library. import ClientCookie response = ClientCookie.urlopen("http://foo.bar.com/") This function behaves identically to urllib2.urlopen, except that it deals with cookies automatically. That's probably all you need to know. John

ANN: Python Imaging Library 1.1.4 beta 1
by PythonWare 30 Apr '03

30 Apr '03

PIL 1.1.4 beta 1 is now available from: http://effbot.org/downloads The distribution is available in source form (look for Imaging tarballs), and as prebuilt installers for Python 2.1, 2.2 and 2.3 (beta 1) on Windows. A list of changes can be found here (also below): http://effbot.org/zone/pil-changes-114.htm ...and a draft handbook can be found here: http://effbot.org/books/imagingbook/ (the main release will be available from www.pythonware.com, as usual) enjoy, the pil team at secret labs ab "Secret Labs AB -- makers of fine pythonware since 1997" *** Changes from release 1.1.3 to 1.1.4 *** (1.1.4 beta 1 released) + Added experimental EXIF support for JPEG files. To extract EXIF information from a JPEG file, open the file as usual, and call the "_getexif" method. If successful, this method returns a dictionary mapping EXIF TIFF tags to values. If the file does not contain EXIF data, the "_getexif" method returns None. The "ExifTags" module contains a dictionary mapping tags to tag names. The "_getexit" interface will most likely change in future versions. + Fixed a bug when using the "transparency" option with the GIF writer. + Added limited support for "bitfield compression" in BMP files and DIB buffers, for 15-bit, 16-bit, and 32-bit images. This also fixes a problem with ImageGrab module when copying screen- dumps from the clipboard on 15/16/32-bit displays. + Added experimental WAL (Quake 2 textures) loader. To use this loader, import WalImageFile and call the "open" method in that module. (1.1.4a4 released) + Added updated SANE driver (Andrew Kuchling, Abel Deuring) + Use Python's "mmap" module on non-Windows platforms to read some uncompressed formats using memory mapping. Also added a "frombuffer" method that allows you to access the contents of an existing string or buffer object as if it were an image object. + Fixed a memory leak that could appear when processing mode "P" images (from Pier Paolo Glave) + Ignore Unicode characters in the BDF loader (from Graham Dumpleton) (1.1.4a3 released; windows only) + Added experimental RGBA-on-RGB drawing support. To use RGBA colours on an RGB image, pass "RGBA" as the second string to the ImageDraw.Draw constructor. + Added support for non-ASCII strings (Latin-1) and Unicode to the truetype font renderer. + The ImageWin "Dib" object can now be constructed directly from an image object. + The ImageWin module now allows you use window handles as well as device contexts. To use a window handle, wrap the handle in an ImageWin.HWND object, and pass in this object instead of the device context. (1.1.4a2 released) + Improved support for 16-bit unsigned integer images (mode "I;16"). This includes TIFF reader support, and support for "getextrema" and "point" (from Klamer Shutte). + Made the BdfFontFile reader a bit more robust (from Kevin Cazabon and Dmitry Vasiliev) + Changed TIFF writer to always write Compression tag, even when using the default compression (from Greg Couch). + Added "show" support for Mac OS X (from Dan Wolfe). + Added clipboard support to the "ImageGrab" module (Windows only). The "grabclipboard" function returns an Image object, a list of filenames (not in 1.1.4), or None if neither was found. (1.1.4a1 released) + Improved support for drawing RGB data in palette images. You can now use RGB tuples or colour names (see below) when drawing in a mode "P" image. The drawing layer automatically assigns color indexes, as long as you don't use more than 256 unique colours. + Moved self test from MiniTest/test.py to ./selftest.py. + Added support for CSS3-style color strings to most places that accept colour codes/tuples. This includes the "ImageDraw" module, the Image "new" function, and the Image "paste" method. Colour strings can use one of the following formats: "#f00", "#ff0000", "rgb(255,0,0)", "rgb(100%,0%,0%)", "hsl(0, 100%, 50%)", or "red" (most X11-style colour names are supported). See the documentation for the "ImageColor" module for more information. + Fixed DCX decoder (based on input from Larry Bates) + Added "IptcImagePlugin.getiptcinfo" helper to extract IPTC/NAA newsphoto properties from JPEG, TIFF, or IPTC files. + Support for TrueType/OpenType fonts has been added to the standard distribution. You need the freetype 2.0 library. + Made the PCX reader a bit more robust when reading 2-bit and 4-bit PCX images with odd image sizes. + Added "Kernel" class to the ImageFilter module. This class allows you to filter images with user-defined 3x3 and 5x5 convolution kernels. + Added "putdata" support for mode "I", "F" and "RGB". + The GIF writer now supports the transparency option (from Denis Benoit). + A HTML version of the module documentation is now shipped with the source code distribution. You'll find the files in the Doc subdirectory. + Added support for Palm pixmaps (from Bill Janssen). This change was listed for 1.1.3, but the "PalmImagePlugin" driver didn't make it into the distribution. + Improved decoder error messages. -end-

ANN: SimPy 1.2 released (Simulation in Python package)
by Klaus Muller 30 Apr '03

30 Apr '03

We have just released the production version 1.2 of the SimPy simulation package. It is available for download from the SimPy home page at http://simpy.sourceforge.net. Version 1.2 is faster, more capable (e.g. asynchronous interrupts), has better documentation and errror messages, and comes with more simulation models. SimPy is a discrete event, object-oriented, system simulation package for Python 2.2 and later (fully tested with Python 2.3a1). It uses generators which support efficient implementation of coroutines. It allows easy interfacing to GUIs and graphing packages for analysis. A manual, a tutorial, a simple cheatsheet, browsable sourcecode documentation and many examples are included in the download. SimPy is platform-independent. Enjoy!

Kodos 1.2 - Python regular expression visual debugging tool
by stuff＠mailzilla.net 29 Apr '03

29 Apr '03

Kodos 1.2 has been released and is available at: http://kodos.sourceforge.net Kodos is a regular expression designer, tester, debugger and validator that allows a developer to create and modify regular expressions against a test string. The intuitive grahpical interface allows the developer the ability to modify the regular expression (regex) and to see the effects against their test string in real-time. Key Features: - Matches can be easily viewed and each match can be seen distinctly - Regex groups and named groups are clearly displayed - Sample source code is shown so even python developers new to regular expressions can quickly add the produced regular expressions to their own projects. - Ability to load and save your test cases - Kodos relies on PyQt for the GUI elements. Changes since 1.1: * File menu now contains recently accessed kodos files (.kds) * Preferences allows you to edit control the number of recent files that appear * regex reference guide has been expanded to include more entries * Preferences are migrated from .kodos to .kodos/prefs * New settings file .kodos/recent_files added * Bug fix for Windows (Kodos mysteriously exited on startup) * Added preference for processing timeout. * Other minor fixes, cleanup, etc... http://kodos.sourceforge.net

ctypes 0.6.0 released
by Thomas Heller 29 Apr '03

29 Apr '03

Overview 'ctypes' is a Python package to create and manipulate C data types in Python, and to call functions in dynamic link libraries/shared dlls. It allows wrapping these libraries in pure Python. It works on Windows, Linux and MacOS X (the latter two require that your machine is supported by libffi). News *ctypes version 0.6.0 has been released*, and the documentation has been updated. There have been some (also incompatible) changes, but I'm quite pleased with the result: ctypes is much more consistent than before. COM A proof-of-concept COM framework has been implemented, and added to the package. It is in an early stage, although usable, and I would like experienced COM developers to look at it, and submit feedback. Homepage http://starship.python.net/crew/theller/ctypes.html Thomas

ANN: Jestur 0.2b gesture recognition module
by simon.wittber＠perth.maptek.com.au 28 Apr '03

28 Apr '03

Jestur is a simple gesture recognition module for Python. For more information, visit http://sourceforge.net/projects/jestur What's New in 0.2b ================== * I've replaced the cpu consuming neural network code with a faster, dodgier pattern matching algorithm. * User's can easily add their own custom gestures. * Removed the dependency on the pygame event queue. What is Jestur? ================ Jestur is a set of simple classes which provide gesture recognition facilities to Python. It works by capturing consecutive (x,y) co-ordinates, and normalizing them into mouse movement directions, which it then compares to a lookup of gesture patterns using a scoreboard style algorithm. The included testjestur.py uses the pygame library to demonstrate functionality.
