| If you have a digital camera, you have a powerful tool for building activites in applications such as IntelliTools Classroom Suite® and My Own Bookshelf®. It is fairly easy to transfer those digital photos into your computer. All that talk about pixels and megapixels may be a little confusing, however, when you begin to think about using the photos. |
| Basically, a pixel is one sample element from a digital picture, and usually it is displayed as a dot. One million of them make up a megapixel. |
A digital photo is displayed as rows of these dots, and usually the width and height in pixels is used to describe the resolution of the photo. Multiply these together, and you get the total number of pixels, and divide that by one million and you have the total megapixels in that photo. Cameras are often described in terms of the largest resolution photo they can take. As you can see from this example, if the camera can take photos 2048X1536, that's about a 3.1 megapixel camera. |  |
| But the default page size for your applications may not hold that many pixels. For example, the full page in IPS3 by default is 800X600, or only about half a megapixel. If you have a text box on the page, you will have room for even fewer megapixels of graphics. |
