Understanding Vector Graphics
Vector graphics represent images using mathematical formulas that define points, lines, curves, and shapes on a plane. This format contrasts with raster images, which are made up of pixels.
Difference Between Raster and Vector
Raster graphics are composed of a fixed set of dots called pixels, where each pixel is assigned a color value. In contrast, vector graphics consist of paths defined by a start and end point, along with other points, curves, and angles. A key property of vector images is that they are scalable. This means that they can be enlarged or reduced without losing quality, as they are resolution-independent.
Advantages of Vectorizing
Vectorizing an image allows for more flexibility in editing and manipulation. Vectors can be resized without degradation, which is especially important for logos or any graphics needing to be used across multiple formats. Furthermore, the editability of vector images enables designers to make precise adjustments to individual elements without affecting the whole.
