Vector graphics editors are often contrasted with raster graphics editors, yet their capabilities complement each other. The technical difference between Vector and Raster editors stem from the difference between vector and raster images. Vector images are created mathematically (using formulas, as in geometry). Each element is created and manipulated numerically; essentially using Cartesian coordinates for the placement of key points, and then a mathematical algorithm to connect the dots and define the colors.
Raster images include digital photos. A raster image is made up of pixels, and is generally more photo-realistic. This is the standard form for digital cameras; whether it be .raw format or .jpg, the concept is the same. The image is represented pixel by pixel, dot by dot, almost like a micro jigsaw puzzle where each pixel is a puzzle piece.
Vector editors tend to be better suited for graphic design, page layout, typography, logos, sharp-edged artistic illustrations (e.g. cartoons, clip art, complex geometric patterns), technical illustrations, diagramming and flowcharting.
Advanced Raster editors (like Photoshop) use vector methods (mathematics) for general layout and elements such as text, but are equipped to deal with raster images down to the pixel and often have special capabilities in doing so, such as brightness/contrast, and even adding "lighting" to a raster image or photograph.
Raster editors are more suitable for retouching, photo processing, photo-realistic illustrations, collage, and hand drawn illustrations using a graphics tablet. Many contemporary illustrators use Corel Photo-Paint, Photoshop, GIMP, and other raster editors to make all kinds of illustrations. 21st century versions of such editors support vector-like tools (e.g. editable paths),
Great job IT teacher. A brief overview on raster to vector conversion and the difference of both graphic types. Thanks.
