Pixle's and raster effects in graphics

A pixel is a small rectangle that holds color information for an image and is commonly used in 2D games Such as Super Mario. Each pixel is importent because it holds the color information to an image and withought pixels you would have no image on your TV, Laptop or Mobile Phone.

Raster graphics can be Resized but they will lose quality because as the image gets larger so must the pixels however this does not happen with vector graphics which can be enlarged and shrunk to any size, for example they can be resized so that an image fits on a small buisness card and thye image will not lose quality when it is being made to fit.

Jpegs and Png (ping) files are more commonly used in uploading pictures onto the iternet as they do not lose much quality when they are resized to fit on a screan but you can still see them clearly enough so you can view them when they are mabye half or double the size they origanally were to begin with.

An EPS file can contain any combination of text, graphics and images. Since it is actually a PostScript file, it is one of the most versatile file formats that are available. EPS-files usually contain a small preview image that is used to visualize the content of the file. This is done so that applications don’t need a PostScript interpreter to display the content of the EPS file.
