This series is dedicated to the students of the Systems Department, to give them reading material related to computer science in a second language. This book covers Internet and Multimedia Technology, System Analysis and Design, and Software Engineering. 4 | P a g e Preface This series of textbooks was created for the students of the Systems Engineering Program at the University of Nariño. They have been intentionally written in English to promote reading in a foreign language. The textbooks are a collection of reflections and workshops on specific situations in the field of computer science, based on the authors’ experiences. The main purpose of these textbooks is essentially academic. The way in which the reflections and workshops were constructed follows a didactic structure, to facilitate teaching and learning, making use of English as a second language.

  • Programming Windows Presentation Foundation by Ian Griffiths, Chris Sells
    Programming Windows Presentation Foundation By Ian Griffiths, Chris Sells ............................................... Publisher: O'Reilly Pub Date: September 2005 ISBN: 0-596-10113-9 Pages: 447 Slots: 1.0 Table of Contents | Index Windows Presentation Foundation (WPF) (formerly known by its code name "Avalon") is a brand-new presentation framework for Windows XP and Windows Vista, the next version of the Windows client operating system. For developers, WPF is a cornucopia of new technologies, including a new graphics engine that supports 3-D graphics, animation, and more; an XML-based markup language (XAML) for declaring the structure of your Windows UI; and a radical new model for controls. Programming Windows Presentation Foundation is the book you need to get up to speed on WPF. By page two, you'll have written your first WPF application, and by the end of Chapter 1, "Hello WPF," you'll have completed a rapid tour of the framework and its major elements. These include the XAML markup language and the mapping of XAML markup to WinFX code; the WPF content model; layout; controls, styles, and templates; graphics and animation; and, finally, deployment. Programming Windows Presentation Foundation features: ● Scores of C# and XAML examples that show you what it takes to get a WPF application up and running, from a simple "Hello, Avalon" program to a tic-tac-toe game ● Insightful discussions of the powerful new programming styles that WPF brings to Windows development, especially its new model for controls ● A color insert to better illustrate WPF support for 3-D, color, and other graphics effects ● A tutorial on XAML, the new HTML-like markup language for declaring Windows UI ● An explanation and comparison of the features that support interoperability with Windows Forms and other Windows legacy applications The next generation of Windows applications is going to blaze a trail into the unknown.

A diffusion curve parti- dates back to the earliest days of our field. Early cathode-ray tubes, tions the space through which it is drawn, defining different colors starting with the Whirlwind-I in 1950, were all vector displays, on either side. These colors may vary smoothly along the curve. In while the seminal Sketchpad system [Sutherland 1980] allowed addition, the sharpness of the color transition from one side of the users to manipulate geometric primitives like points, lines, and curve to the other can be controlled. Given a set of diffusion curves, curves. Raster graphics provides an alternative representation for the final image is constructed by solving a Poisson equation whose describing images via a grid of pixels rather than geometry. Raster constraints are specified by the set of gradients across all diffusion graphics arose with the advent of the framebuffer in the 1970s and curves. Like all vector-based primitives, diffusion curves conve- is now commonly used for storing, displaying, and editing images. niently support a variety of operations, including geometry-based However, while raster graphics offers some advantages over vector editing, keyframe animation, and ready stylization.
