Explain what a vector graphic is and how it is defined. Discuss how vector graphics display on various monitors, and how shapes within vector graphics can be modified. Review the advantages of vector graphic files over bitmap graphic files, and the types of programs that can be used to create them.
What will be an ideal response?
A vector graphic is a set of mathematical instructions that describes the color, outline, and position of all the shapes of the image. Each shape is defined by numbers that represent the shape's position in the window in which it is being displayed. Other numbers represent the points that establish the shape's outline. As a result, vector graphics scale well, which means you can resize a vector image proportionally and the quality remains the same. Vector graphics excel at sharp lines, smooth colors, and precise details. Vector graphic files are generally smaller than bitmap graphic files and take less time to download. Common examples of vector graphics are images created in drawing programs such as Adobe Illustrator as well as images created in Flash.
