(a)   are composed of a grid of pixels, with the resolution of the image defined by pixels per inch (PPI) or dots per inch (DPI). Since the resolution is defined by the number of pixels and dimensions, scaling the image beyond the original dimensions will result in a loss of quality, often referred to as pixelation. ​ (b)   s created by a mathematical formula using points and paths and can be scaled without losing quality.

• Raster Images
• Vector Images

What is a benefit of using vector image formats?

• They are always larger in file size than raster images.

• They are infinitely scalable without losing quality.

• They lose quality when resized.

• They are composed of pixels.

Select the (2) descriptions that best describe Raster Images:

• Scaling the image beyond the original dimensions will result in a loss of quality, often referred to as pixelation.

• Can be scaled without losing quality.

• Commonly used for graphics and logos that may need to be resized to fit a variety of applications.

• Commonly used for web graphics, print media and digital photography
