[ANN] guiqwt v2.1.0
by Pierre.RAYBAUT＠CEA.FR 06 Apr '11

06 Apr '11

Hi all, I am pleased to announce that `guiqwt` v2.1.0 has been released. Note that the project has recently been moved to GoogleCode: http://guiqwt.googlecode.com This version of `guiqwt` includes a demo software, Sift (for Signal and Image Filtering Tool), based on `guidata` and `guiqwt`: http://packages.python.org/guiqwt/sift.html Windows users may even download the portable version of Sift 0.22 to test it without having to install anything: http://code.google.com/p/guiqwt/downloads/detail?name=sift022_portable.zip The `guiqwt` documentation with examples, API reference, etc. is available here: http://packages.python.org/guiqwt/ Based on PyQwt (plotting widgets for PyQt4 graphical user interfaces) and on the scientific modules NumPy and SciPy, guiqwt is a Python library providing efficient 2D data-plotting features (curve/image visualization and related tools) for interactive computing and signal/image processing application development. When compared to the excellent module `matplotlib`, the main advantage of `guiqwt` is performance: see http://packages.python.org/guiqwt/overview.html#performances. But `guiqwt` is more than a plotting library; it also provides: * Helper functions for data processing: see the example http://packages.python.org/guiqwt/examples.html#curve-fitting * Framework for signal/image processing application development: see http://packages.python.org/guiqwt/examples.html * And many other features like making executable Windows programs easily (py2exe helpers): see http://packages.python.org/guiqwt/disthelpers.html guiqwt plotting features are the following: guiqwt.pyplot: equivalent to matplotlib's pyplot module (pylab) supported plot items: * curves, error bar curves and 1-D histograms * images (RGB images are not supported), images with non-linear x/y scales, images with specified pixel size (e.g. loaded from DICOM files), 2-D histograms, pseudo-color images (pcolor) * labels, curve plot legends * shapes: polygon, polylines, rectangle, circle, ellipse and segment * annotated shapes (shapes with labels showing position and dimensions): rectangle with center position and size, circle with center position and diameter, ellipse with center position and diameters (these items are very useful to measure things directly on displayed images) curves, images and shapes: * multiple object selection for moving objects or editing their properties through automatically generated dialog boxes (guidata) * item list panel: move objects from foreground to background, show/hide objects, remove objects, ... * customizable aspect ratio * a lot of ready-to-use tools: plot canvas export to image file, image snapshot, image rectangular filter, etc. curves: * interval selection tools with labels showing results of computing on selected area * curve fitting tool with automatic fit, manual fit with sliders, ... images: * contrast adjustment panel: select the LUT by moving a range selection object on the image levels histogram, eliminate outliers, ... * X-axis and Y-axis cross-sections: support for multiple images, average cross-section tool on a rectangular area, ... * apply any affine transform to displayed images in real-time (rotation, magnification, translation, horizontal/vertical flip, ...) application development helpers: * ready-to-use curve and image plot widgets and dialog boxes * load/save graphical objects (curves, images, shapes) * a lot of test scripts which demonstrate guiqwt features guiqwt has been successfully tested on GNU/Linux and Windows platforms.

PyPy Gothenburg Post-Easter Sprint April 25 - May 1 2011
by Laura Creighton 04 Apr '11

04 Apr '11

PyPy Göteborg Post-Easter Sprint April 25 - May 1 2011 ====================================================== The next PyPy sprint will be in Gothenburg, Sweden. It is a public sprint, very suitable for newcomers. We'll focus on making the 1.5 release (if it hasn't already happened) and whatever interests the Sprint attendees. Topics and goals ---------------- The main goal is to polish and release PyPy 1.5, supporting Python 2.7 as well as the last few months' improvements in the JIT (provided that it hasn't already happened). Other topics: - Going over our documentation, and classifying our docs in terms of mouldiness. Deciding what needs writing, and maybe writing it. - Helping people get their code running with PyPy - maybe work on EuroPython Training, and talks - Summer of Code preparation - speed.pypy.org - any other programming task is welcome too -- e.g. tweaking the Python or JavaScript interpreter, Stackless support, and so on. Location -------- The sprint will be held in the apartment of Laura Creighton and Jacob Hallén which is at Götabergsgatan 22 in Gothenburg, Sweden. Here is a map_. This is in central Gothenburg. It is between the tram_ stops of Vasaplatsen and Valand, (a distance of 4 blocks) where many lines call -- the 2, 3, 4, 5, 7, 10 and 13. .. _tram: http://www.vasttrafik.se/en/ .. _map: http://bit.ly/grRuQe Probably cheapest and not too far away is to book accomodation at `SGS Veckobostader`_. The `Elite Park Avenyn Hotel`_ is a luxury hotel just a few blocks away. There are scores of hotels a short walk away from the sprint location, suitable for every budget, desire for luxury, and desire for the unusual. You could, for instance, stay on a `boat`_. Options are too numerous to go into here. Just ask in the mailing list or on the blog. .. _`SGS Veckobostader`: http://www.sgsveckobostader.se/en .. _`Elite Park Avenyn Hotel`: http://www.elite.se/hotell/goteborg/park/ .. _`boat`: http://www.liseberg.se/en/home/Accommodation/Hotel/Hotel-Barken-Viki ng/ Hours will be from 10:00 until people have had enough. It's a good idea to arrive a day before the sprint starts and leave a day later. In the middle of the sprint there usually is a break day and it's usually ok to take half-days off if you feel like it. Good to Know ------------ Sweden is not part of the Euro zone. One SEK (krona in singular, kronor in plural) is roughly 1/10th of a Euro (9.36 SEK to 1 Euro). The venue is central in Gothenburg. There is a large selection of places to get food nearby, from edible-and-cheap to outstanding. We often cook meals together, so let us know if you have any food allergies, dislikes, or special requirements. Sweden uses the same kind of plugs as Germany. 230V AC. The Sprint will be held the week following Easter. This means, as always, that Gothcon_ will be taking place the weekend before (Easter weekend). Gothcon, now in its 35 year, is the largest European game players conference. Some of you may be interested in arriving early for the board games. The conference site is only in Swedish, alas. You don't need to register in advance unless you are planning to host a tournament, (and it's too late for that anyway). .. _Gothcon: http://www.gothcon.se/ Getting Here ------------ If are coming train, you will arrive at the `Central Station`_. It is about 12 blocks to the site from there, or you can take a tram_. There are two airports which are local to Göteborg, `Landvetter`_ (the main one) and `Gothenburg City Airport`_ (where some budget airlines fly). If you arrive at `Landvetter`_ the airport bus stops right downtown at `Elite Park Avenyn Hotel`_ which is the second stop, 4 blocks from the Sprint site, as well as the end of the line, which is the `Central Station`_. If you arrive at `Gothenburg City Airport`_ take the bus to the end of the line. You will be at the `Central Station`_. You can also arrive by ferry_, from either Kiel in Germany or Frederikshavn in Denmark. .. _`Central Station`: http://bit.ly/fON43p .. _`Landvetter`: http://swedavia.se/en/Goteborg/Traveller-information/Traffic-i nformation/ .. _`Gothenburg City Airport`: http://www.goteborgairport.se/eng.asp .. _ferry: http://www.stenaline.nl/en/ferry/ Who's Coming? -------------- If you'd like to come, please let us know when you will be arriving and leaving, as well as letting us know your interests We'll keep a list of `people`_ which we'll update (which you can do so yourself if you have bitbucket pypy commit rights). .. _`people`: https://bitbucket.org/pypy/extradoc/src/tip/sprintinfo/gothenburg- 2011/people.txt

PyUseCase 3.5: GUI test tool written in Python
by Geoff Bache 01 Apr '11

01 Apr '11

Hi all, PyUseCase now includes support for SWT/Eclipse RCP, using Jython and SWTBot. This is alongside earlier support for wxPython, Tkinter and PyGTK. There are also a fair few enhancements to the "shortcut" mechanism for test refactoring. Full details are in the ChangeLog in the download. Regards, Geoff Bache A bit more detail: PyUseCase is an unconventional GUI testing tool for PyGTK, Tkinter, wxPython and SWT along with a framework for testing Python GUIs in general. Instead of recording GUI mechanics directly, it asks the user for descriptive names and hence builds up a "domain language" along with a "UI map file" that translates this language into actions on the current GUI widgets. The point is to reduce coupling, allow very expressive tests, and ensure that GUI changes mean changing the UI map file but not all the tests. Instead of an "assertion" mechanism, it auto-generates a log of the GUI appearance and changes to it. The point is then to use that as a baseline for text-based testing, using TextTest. It also includes support for instrumenting code so that "waits" can be recorded, making it far easier for a tester to record correctly synchronized tests without having to explicitly plan for this.
