Vektorointiin

Vektorointiin, often translated as vectorization, is a process in computer graphics and image processing where raster images (composed of pixels) are converted into vector graphics (composed of mathematical paths). This transformation allows images to be scaled infinitely without losing quality, as the vector representation defines shapes, lines, and curves based on mathematical equations rather than a fixed grid of pixels.

The primary purpose of vectorization is to achieve scalability and editability. When a raster image is scaled up, its pixels become larger and more visible, resulting in a pixelated or blurry appearance. In contrast, a vectorized image can be enlarged or reduced to any size, and the software will redraw the paths and curves based on their mathematical definitions, maintaining sharp edges and smooth lines. This is particularly useful for logos, illustrations, and designs that need to be used at various sizes, from business cards to billboards.

The process typically involves software that analyzes the raster image to identify shapes and their boundaries. It then generates corresponding vector paths, often with the ability to adjust attributes like stroke width and color. While automatic vectorization tools exist, they may not always produce perfect results, especially with complex or low-resolution raster images. Manual tracing or post-processing is sometimes required to refine the vector output and achieve the desired accuracy and aesthetic. Vector graphics are commonly stored in formats like SVG, AI, and EPS, which are widely used in design and print industries.
