Part 3. Extension Knowledge of Vector Images

a. What is the Definition or a Vector Image?

A Vector image is a computer graphics image that is saleable and consists of values rather than pixels. These image files are defined in terms of 2D points and are connected by the lines and the curves. Constructed using mathematical formulas, vector images offer flexibility, and being resolution-independent these files does not lose quality when scaled up or down. Some of the popular vector formats are EPS, SVG, AI, and PDF.

b. What is a Raster File?

A raster image is made using a grid of pixels known as a bitmap. Majority of the photos on the web and imported from the cameras are in raster format. A raster file format uses individual building blocks to form a complete picture or an image and contains a lot of details. As raster image needs to include a lot of information, a large bitmap will require a large file size. Since the fixed number of colored pixels is used for forming a raster image, they cannot be resized without compromising on the quality and the resolution. Some of the popularly used raster formats are JPG, PNG, and GIF.

Therefore, a JPG format is best for using pictures on a website.

b. PNG: PNG is also a raster image file format that is best used for creating logos, icons and other files where the transparent background is needed. In comparison to JPG, a PNG file offers a larger image and high quality along with an option for transparent background.

c. TIF: Another popularly used raster image format is TIF which is also known as TIFF. The format is best used for high-quality printing as there is no quality loss. TIF is not preferred on the web as the file takes up a lot of loading time.
