  • Just as the camera is no longer relegated to the elite or industry professionals, Photoshop is no longer considered the tool of graphic designers alone. Whether it is used to scan photographs, paint a landscape, apply effects to text, create Web pages, or alter images, the application enables all users to accomplish one common feat: to produce professional-quality images in virtually any digital format. You may be surprised at how many people outside of the design industry are aware of and have even used Adobe Photoshop.

  • Chapter 12 demonstrated how to create simple windows and display basic shapes: rectangle, circle, triangle, and ellipse. It showed how to manipulate such shapes: change colors and line style, add text, etc. Chapter 13 shows how these shapes and operations are implemented, and shows a few more examples. In Chapter 12, we were basically tool users; here we become tool builders.

  • Operating Systems interpret user commands and instructions (like typing on the keyboard or clicking with the mouse) and send requests to the proper application or device. An OS not only provides a user interface (text or graphic) to access/organize/manipulate/store data, but can also provide security and multitasking capabilities. Generally the OS is made up of a few core files with additional files for extended functionality and backward capability.

  • Two of the most important functions for signal processing are not in the Signal Processing Toolbox at all, but are built-in MATLAB functions: • filter applies a digital filter to a data sequence. • fft calculates the discrete Fourier transform of a sequence. The operations these functions perform are the main computational workhorses of classical signal processing. Both are described in this chapter.

  • GraphicS and interaction PART II Part II represents the largest section of the book, spanning Chapter 3 through Chapter 9. This part covers many significant features that distinguish ActionScript 3.0 from prior versions. It focuses on graphics and interactions and includes the new event model and display list. Chapter 3 is a discussion of properties, events, and methods—the items responsible for manipulating just about anything in Flash. Chapter 4 goes on to explain the display list, a great new way to display visual assets in Flash.

  • SIGNAL-FLOW GRAPHS AND APPLICATIONS A signal-¯ow graph is a graphical means of portraying the relationship among the variables of a set of linear algebraic equations. S. J. Mason originally introduced it to represent the cause-and-effect of linear systems. Associated terms are de®ned in this chapter along with the procedure to draw the signal-¯ow graph for a given set of algebraic equations. Further, signal-¯ow graphs of microwave networks are obtained in terms of their S-parameters and associated re¯ection coef®cients.

  • The Graphics Class Using Bitmap Fills and Lines In addition to applying gradients to fills and lines, you can use bitmaps to decorate your drawing’s fills and lines. Both the beginBitmapFill() and lineBitmapStyle() methods we cover in this section use instances of the BitmapData class. This class handles pixel color and alpha data and allows low-level manipulation of bitmaps. Conveniently, BitmapData is also the data type of bitmaps instantiated from the Flash Professional library using a linkage class.

  • The table in Figure 4 summarizes the models discussed above. These components provide a starting point for our research. In fact, there are too many to test within the scope of this project, so some choices must be made. The main consideration is that some properties, such as complexity, dominance (providing a focal point), and grouping, may lend themselves more easily to the visualization environment than others. A secondary consideration is the techniques for manipulating the chosen properties. Section 3 surveys aesthetic techniques that have been developed in computer graphics....
