Vector vs pixel images

What is a vector image? Vector graphics use geometrical points, lines, curves, and shapes based on mathematical equations to represent images in computer graphics.

What is a pixel based image? Pixel-based images are photographic files converted to grids of small rectangular cells (pixels). The smaller and closer together the cells, the better the quality of the image. When a pixel image is enlarged, it can appear grainy (pixellated) because the eye can distinguish individual cells.

An understanding of the advantages and limitations of each format and how they can work together, is important for eliminating and/or resolving image degradation.
