Where can you get graphics This chapter will show you a wide range of ways that you can get graphics for your slides, but one of the most useful resources you will use is a stock photography Web site. Stock photography Web sites feature a database that you can search to locate photographs, as well as illustrations, motion graphics, and video. It s important that you properly obtain a license or otherwise get permission to use graphics if you do not already hold the rights to use them. Stock photography Web sites are set up to make the licensing process easy. The cost of licensing photographs ranges from free to hundreds of dollars or more. In this chapter, you will use a stock photography Web site called iStockphoto, which has a database of more than 2 million images that you can search; you can license most of the photos for use in your presentations for only a few dollars each. You can nd a number of similar stock photography Web sites by doing a Web search for terms such as stock photography presentations. What s your budget If you have a budget of $0, you will be limited to only free graphics, screen captures, and any graphics you can create yourself. If you have a budget of $20, you can license 10 photographs from iStockphoto for $2 each; if you have $500, you can hire a freelance graphic designer for perhaps 10 hours; and if you have $10,000, you can commission a video that you integrate into your Key Point slides and elsewhere through the storyboard.

1 <= number <= 10 The and operator is a so-called Boolean operator. It takes two truth values, and returns true if both are true, and false otherwise. You have two more of these operators, or and not. With just these three, you can combine truth values in any way you like: if ((cash > price) or customer_has_good_credit) and not out_of_stock: give_goods()

What other resources do you have available If you have the skills, you can create original illustrations yourself in another software program, or you can shoot your own photographs and edit them with image editing software. If you don t have these skills, consider other people you can ask for help, such as an in-house design team or your coworkers. If you have the budget, you can outsource the entire task of adding graphics to a professional graphic designer. Whatever constraints you have, you don t need design training to produce effective results with your new PowerPoint storyboard. This chapter will introduce and demonstrate a number of new tools and basic design techniques that you can start applying to your PowerPoint presentations today.

You can make your own class, implement an each method, and get these methods for free :

This is a class that, in reality, doesn t need to provide multiple objects, as it only provides an enumeration of vowels. However, to keep the demonstration simple, it is ideal. Here s how it works:

The most important thing to keep in mind when you add graphics to your storyboard is that you re not just designing slides; you re designing a complete experience that manages the visual and verbal channels for the working memory of your audience. It s easy to become absorbed in the details of fonts, graphics, and animations on the slides while losing track of your spoken words and how the entire experience helps the audience to understand your message. To make sure you keep on track, keep three ground rules in mind while you re working with graphics.

The Boolean operators have one interesting property: They only evaluate what they need to. For example, the expression x and y requires both x and y to be true; so if x is false, the expression returns false immediately, without worrying about y. Actually, if x is false, it returns x otherwise it returns y. (Can you see how this gives the expected meaning ) This behavior is called short-circuit logic: the Boolean operators are often called logical operators, and as you can see, the second value is sometimes short-circuited. This works with or, too. In the expression x or y, if x is true, it is returned, otherwise y is returned. (Can you see how this makes sense ) So, how is this useful Let s say a user is supposed to enter his or her name, but may opt to enter nothing, in which case you want to use the default value '<unknown>'. You could use an if statement, but you could also state things very succinctly:
