What is the Difference Between Raster and Vector Graphics?

The main difference between raster and vector graphics lies in the way they are composed and represented. Raster graphics are made up of pixels, while vector graphics are composed of paths using mathematical formulas. Here are some key differences between the two:

1. Composition: Raster graphics are composed of pixels, which are arranged in a grid to display an image. Vector graphics, on the other hand, are composed of paths and mathematical formulas that determine the design.
2. Scalability: Vector graphics are scalable without losing quality, as they are based on mathematical formulas. Raster graphics, being composed of pixels, become pixelated when enlarged.
3. File Size: Raster files are generally larger than vector files, as they contain millions of pixels and high levels of detail. Vector files are more lightweight, containing only the mathematical formulas that determine the design.
4. Compatibility and Conversion: Raster files can be opened in many different apps and web browsers, making them easy to view, edit, and share. Vector files require specialized software to open and edit. It is possible to convert vector files to raster or raster files to vector when needed, but some loss of quality may occur during the conversion process.
5. Usage: Raster images are best for digital photos and print materials with complex color blends. Vector graphics are suitable for logos, illustrations, etchings, product artwork, and engravings, as they can be scaled to different sizes without pixelating.

In summary, raster graphics are best for images with complex color blends and photorealistic details, while vector graphics are ideal for logos, illustrations, and designs with simple and solid colors that need to be scalable without losing quality.

Comparative Table: Raster vs Vector Graphics

Here is a table comparing the differences between raster and vector graphics:

Raster graphics are made up of pixels and are constrained by resolution and dimensions, while vector graphics are composed of paths dictated by mathematical formulas, allowing for infinite scalability. Raster graphics are suitable for digital photos and graphic design, while vector graphics are ideal for logos, illustrations, icons, and other graphics that require scalability and smooth lines.
