There is a stand-alone program in wide use by astronomers that does 2D floating-point image display called ds9. It has a 2-way numpy interface and a rich set of image viewing/annotating features, including interactive colormapping, zoom/pan of very large images, n-up displays, movies, live row and column plots, etc. See http://hea-www.harvard.edu/RD/ds9/ There is also the lighter, native-Python ntv routine, which uses matplotlib: http://planets.ucf.edu/resources/open-source-software/ http://code.google.com/p/ntv/ This is a new package that can display 2D floating-point arrays as images and do some astro-specific stuff like point-source centering and extraction (aka photometry) from images. The author, Nate Lust, is eager for contributions, such as help in adding features and improving the web pages for it. It would probably be straightforward to add a table-viewing/editing feature to this, such that you would click in an image and get a spreadsheet-like interface centered where you clicked. --jh-- Date: Fri, 17 Sep 2010 10:46:51 +0530 From: Mayank P Jain Subject: [Numpy-discussion] Viewer for 2D Numpy arrays (GUI) To: numpy-discussion Message-ID: Content-Type: text/plain; charset="iso-8859-1" Currently I am exporting them to csv files, but I wonder if there is a viewer that can be used with native numpy array files to view and preferably modify the 2D arrays. Any help would be appreciated. Regards Mayank P Jain V R TechNiche Transportation Modeler/Planner Phone: +91 901 356 0583
