SciPy for Computational Geometry

by Francisco J. Blanco-Silva | April 2013 | Open Source

In this article by Francisco J. Blanco-Silva, the author of Learning SciPy for Numerical and Scientific Computing, we will cover the routines in the scipy.spatial module that deal with the construction of triangulations of points in spaces of any dimension, and the corresponding convex hulls. The procedure is simple; given a set of m points in the n-dimensional space (which we represent as an m x n NumPy array), we create the scipy.spatial class Delaunay , containing the triangulation formed by those points.

by Cedric Gemy | April 2011 | Open Source

Get exclusive offers on Open Source Graphic Application and Library books through out this month. For more information click here.

If you were asked for the subject of a previously published document without images, which you've read, would you have an answer? I'm not sure you would. Most of the documents now-a-days contain pictures, and computer assisted layout has really made photo placement and handling easy. So you will certainly need to import pictures, either one per day or may be several each day.

In this article by Cedric Gemy, author of Scribus 1.3.5 Beginner's Guide, we'll provide you with the information that will help you secure the formatting and printing of your photos. We will see how to import photos, keep them where we place them, and make sure that they are always where they have been placed, especially in relation to your layout and your original photos.

Seam Data Validation

by David Salter | May 2009 | Java Open Source Web Development

Seam can act as JSF backing beans and as the glue between our server-tier Session Beans and our web-tier JSF pages.
