Hi all, I am pleased to announce that `guiqwt` v2.1.4 has been released.
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. Complete change log is now available here: http://code.google.com/p/guiqwt/wiki/ChangeLog Documentation with examples, API reference, etc. is available here: http://packages.python.org/guiqwt/ 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 0.2.3 to test it without having to install anything: http://code.google.com/p/guiqwt/downloads/detail?name=sift023_portable.zip When compared to the excellent module `matplotlib`, the main advantages of `guiqwt` are: * Performance: see http://packages.python.org/guiqwt/overview.html#performances * Interactivity: see for example http://packages.python.org/guiqwt/_images/plot.png * Powerful signal processing tools: see for example http://packages.python.org/guiqwt/_images/fit.png * Powerful image processing tools: * Real-time contrast adjustment: http://packages.python.org/guiqwt/_images/contrast.png * Cross sections (line/column, averaged and oblique cross sections!): http://packages.python.org/guiqwt/_images/cross_section.png * Arbitrary affine transforms on images: http://packages.python.org/guiqwt/_images/transform.png * Interactive filters: http://packages.python.org/guiqwt/_images/imagefilter.png * Geometrical shapes/Measurement tools: http://packages.python.org/guiqwt/_images/image_plot_tools.png * Perfect integration of `guidata` features for image data editing: http://packages.python.org/guiqwt/_images/simple_window.png But `guiqwt` is more than a plotting library; it also provides: * 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 has been successfully tested on GNU/Linux and Windows platforms.
