Vectorointi

Vectorointi, also known as vectorization, is a process in computer graphics and image processing where raster images are converted into vector graphics. Raster images, such as photographs or scanned drawings, are composed of a grid of pixels, each with a specific color. Vector graphics, on the other hand, are defined by mathematical equations that describe points, lines, curves, and shapes.

The primary advantage of vectorization is that vector graphics are resolution-independent. This means they can be scaled to any size without losing quality or becoming pixelated, unlike raster images which become blurry or jagged when enlarged. Vector graphics are also typically smaller in file size, especially for simple shapes and illustrations.

Vectorization can be performed manually or automatically. Manual vectorization involves tracing over the raster image using vector editing software like Adobe Illustrator or Inkscape. This method offers the highest level of control and precision, allowing for clean lines and accurate shapes. Automatic vectorization utilizes software algorithms to detect edges, shapes, and colors in a raster image and convert them into vector paths. While faster, automatic vectorization may require manual cleanup and adjustments to achieve optimal results, especially for complex or low-quality images.

Common applications for vectorization include logo design, illustration, animation, and technical drawings. It is essential for creating graphics that need to be scaled for various media, from business cards to billboards, ensuring a crisp and professional appearance at any dimension.
