Difference between Raster and Vector
Raster and vector are two methods for creating digital images. Raster graphics are made up of pixels and are best suited for images and complicated images, whereas vector graphics are made of mathematical objects and are best suited for simple shapes and solid colours.
Read this article to find out more about Raster and Vector and how they are different from each other.
What is Raster?
A raster image is made up of small, coloured squares known as pixels. The resolution of a raster image, which is the number of pixels per inch (ppi) or dots per inch (dpi), is used to determine its quality. The higher the resolution, the more detailed the image, but the larger the file size. Raster graphics are suitable for images and other detailed images with a wide range of colours.
Raster graphics have the advantage of being able to capture the minute details of photographic images, such as differences in colour, texture, and shading. Raster graphics are also easily shared and edited because they are widely supported by digital devices and software applications.
However, raster graphics have several limitations. Because they are made up of a set number of pixels, they might become pixelated or unclear when scaled up or printed at a large size. In addition, raster graphics might have huge file sizes, making them unsuitable for web-based applications or other cases where file size is a problem.
Raster graphics are frequently used for pictures and other detailed visuals with numerous colour variations. This is due to the fact that raster images can capture subtle changes in colour and tone that vector graphics cannot. Raster images, on the other hand, might become pixelated or unclear when stretched beyond their initial size, limiting their scalability.
Raster graphics are digital images made up of a grid of pixels, each with its own colour value. Raster graphics are perfect for capturing photographic pictures, but when scaled up or printed at a large size, they might become pixelated or indistinct.
What is Vector?
Vector graphics are digital images made up of mathematical equations defining lines, curves, and forms. Vector graphics, as opposed to raster graphics, are resolution-independent, which means they may be scaled up or down without losing quality.
Each vector object is described by geometric properties such as position, direction, and magnitude. These properties are saved as mathematical equations that can be changed and manipulated without changing the image's quality. This makes vector graphics perfect for creating logos, illustrations, and other images with simple forms and solid colours.
Paths and curves are the most frequent sorts of vector objects, which are specified by anchor points and control handles. Anchor points mark the beginning and end of a path, whereas control handles adjust the direction and curvature of the path between anchor points. Paths can be combined and altered to create complicated shapes and designs.
Vector graphics can be made with specialized software such as Adobe Illustrator, CorelDRAW, and Inkscape. These tools allow designers to generate, edit, and modify vector objects with precision and ease.
Vector graphics are commonly saved in AI, EPS, SVG, and PDF file formats. These formats are extensively supported by design and publishing software and are excellent for printing due to their ability to be scaled up or down without compromising quality. Vector graphics are also extensively used in web design, animation, and interactive media.

Conclusion
In conclusion, raster and vector graphics are two different methods for creating digital images. Raster graphics use pixels and are best suited for pictures and detailed images, whereas vector graphics use mathematical objects and are best suited for simple shapes and solid colours.
The decision between raster and vector graphics depends on the type of image and its intended usage. Understanding the differences between raster and vector graphics will help you select the best tool for your design needs and produce high-quality images that satisfy your specifications.
