What is a common characteristic of raster images compared to vector images?

• A. Raster images are scalable without quality loss
• B. Raster images are based on mathematical formulas
• C. Raster images are made of pixels
• D. Raster images can be edited easily

Answer: (C)

Raster images are characterized by their composition, which consists of a grid of individual pixels. Each pixel contains color information, and together they form the complete image. This pixelated structure is what distinguishes raster images from vector images, which are created using mathematical formulas and geometric shapes. Raster images are resolution-dependent, meaning that if you enlarge them, you may see a loss in image quality, leading to pixelation. In contrast, vector images can be scaled without loss of quality because they are defined by paths rather than pixels. The pixel-based nature of raster images also impacts their editability, as manipulating them often involves adjusting individual pixels rather than large, smooth shapes. Therefore, the fact that raster images are made of pixels is a fundamental characteristic that sets them apart within the digital imaging realm.
