Raster graphics and vector graphics are two different types of computer graphics used to represent and display images. The main difference between them lies in how they store and represent the image data.
Raster graphics, also known as bitmap graphics, are made up of a grid of individual pixels. Each pixel contains specific color information, and when combined, these pixels create the overall image. Raster graphics are resolution-dependent, meaning that the quality and clarity of the image are determined by the number of pixels per inch (PPI) or dots per inch (DPI). Common file formats for raster graphics include JPEG, PNG, and GIF. Raster graphics are best suited for representing complex and detailed images, such as photographs, as they can capture subtle color variations and intricate details.
On the other hand, vector graphics are created using mathematical equations and geometric shapes. Instead of pixels, vector graphics use points, lines, curves, and polygons to define the image. These shapes are stored as mathematical formulas, which can be scaled up or down without losing any quality or clarity. Vector graphics are resolution-independent, meaning they can be resized or zoomed in without any loss of sharpness. Common file formats for vector graphics include SVG, AI, and EPS. Vector graphics are ideal for creating logos, icons, and illustrations, as they can be easily edited and manipulated.
In summary, the main difference between raster graphics and vector graphics is that raster graphics are made up of pixels and are resolution-dependent, while vector graphics are made up of mathematical equations and are resolution-independent. Raster graphics are best for representing complex images with subtle color variations, while vector graphics are ideal for creating scalable and editable designs.
