Chapter 7: Multimedia
Module 1: Computer Graphics With the dawn of the Internet our computer experience has changed from a textual/numerical one to a world of images, sounds, moving pictures, and combinations of all these media. Graphics they way we imagined them on a two-dimensional page have sprung out in three-dimensions that are rotated, can be customized on demand, and can be used in simulating various real experiences. As the world become more vivid in the possible representations we find on our computers, users also become more savvy in manipulating and creating theses multimedia. Bitmapped Graphics: Images on a computer screen are made up of a matrix of pixels, tiny dots of black, white and color arranged in rows. Combination of pixels on the screen outlines the shape of letters, images, and all visual representations that appear on the computer. When painting, or representing an image on the screen there are different approaches of controlling the emerging shape. When free-hand painting is employed where every move form mouse or stylus is captured, as each pixel is determined, we say we are using bitmapped graphics. In this case the information in each pixel is saved in memory and determines the outcome of the whole image. The number of memory bits devoted to each pixel is called color depth, or bit depth, and in helps the artist create more realistic looking images. Another factor is resolution, which indicates the density of the pixels, usually described in dots per inch, dpi. Not surprising that these are common words used to describe the quality of your computer monitor’s image quality. The advantage of using bitmapped graphics is the control over detail and richness of the image but there is a price to pay in the use of memory. More information devoted to each pixel, translates in a better image but also in more use of memory space in your computer. Object-Oriented Graphics: There are times when you just want to draw a shape, like a circle, a
