This is week number 6 of the course. In week number 6, we will talk about computer graphics. Computer graphics can be categorized into two different types. The first type is called bitmap images. So they are based on pixels. So you zoom into the image, you will see all the pixels within the image. The second type is called vector images. For vector image, all the objects within images are represented continuously using mathematical equations. So that's why it's going to look good even if we zoom into the image. This is an example of bitmap image. If you zoom into the image, you will see all the pixel. This is an example of a vector image, which we use different mathematical equations if you draw the same tiger. If we are talking about bitmap images, the number of pixels that we use to represent the image is going to affect the quality of the image. The more pixels that we use, the better the quality of the image. Notice that the colors depth, which is the number of colors that we use on the image is also going to affect the quality of the image. The more colors that we use, the better the quality of the image. In this module, we'll also talk about different file formats that we can use for storing images. For example, the bitmap file format, gif, png, jpg, and also svg for vector images. We'll also talk about GIMP, which is an alternative to Adobe Photoshop for manipulating images.
