What is the difference between Raster and Vector Images 

Raster and vector are two different types of digital graphic formats used to create and store images. The main difference between raster and vector graphics lies in how they store and represent visual information.

Raster Graphics

Raster graphics, also known as bitmap images, are composed of tiny pixels, each of which contains information about color and brightness. When a raster image is created or enlarged, the software adds new pixels to the image, which can lead to a loss of quality and detail. Raster images are resolution-dependent, meaning that their quality and clarity are directly proportional to the number of pixels in the image. A higher number of pixels translates to a higher resolution, which leads to better clarity and detail.

Raster graphics are used in a variety of applications, including digital photography, web graphics, and video games. Examples of raster file formats include JPEG, PNG, GIF, and BMP.

Vector Graphics

Vector graphics, on the other hand, are based on mathematical formulas that describe the properties of geometric shapes. Vector images are composed of paths and curves, which are defined by mathematical equations rather than pixels. This means that vector graphics can be scaled up or down without losing quality or resolution.

Vector graphics are commonly used for creating logos, typography, and other designs that require sharp, clean lines and precise shapes. They are also used in CAD (Computer-Aided Design) applications, technical drawings, and illustrations. Examples of vector file formats include AI, EPS, PDF, and SVG.

The main differences between raster and vector graphics can be summarized as follows: 

Scaling

When a raster image is enlarged, the software adds new pixels to the image, which can lead to a loss of quality and detail. On the other hand, vector images can be scaled up or down without losing quality or resolution, as the mathematical equations that define the shapes can be recalculated to fit the new size.

Resolution

Raster graphics are resolution-dependent, meaning that their quality and clarity are directly proportional to the number of pixels in the image. Vector graphics, on the other hand, are resolution-independent and can be printed or displayed at any size without losing quality.

File size

Raster images can be large in file size, especially if they have a high resolution. Vector graphics, on the other hand, are typically smaller in file size, as they contain only mathematical formulas and not individual pixels.

Editing

Raster images are edited pixel by pixel, which can be time-consuming and limit the precision of the edits. Vector images, on the other hand, are edited using mathematical equations that define the shapes, allowing for precise and efficient editing.

Usage

Raster graphics are typically used for photographs, web graphics, and video games, while vector graphics are used for logos, typography, technical drawings, and illustrations.

In summary, both raster and vector graphics have their strengths and weaknesses, and the choice of which format to use depends on the specific application and requirements of the project.
