Drawing packages
Images made with drawing packages consist of lines, shapes and co-ordinates. Drawing packages are also known as vector drawing packages. Generally a drawing package offers many similar features to a painting.
Vector graphics
Vector graphics are based on mathematical relationships with control points that make up the image. Information is not stored about each One of the individual units (often called dots) that make up an image.. These points are connected by lines and curves called vector paths or vectors.
Vector objects
A vector object is a shape made up of vector paths. It is possible to edit each object separately, for example, change the shape, stroke, fill, size and position. A stroke follows the outline of the vector path and a fill adds a colour to the area inside the path.
Advantages
- Smaller file size - vector graphics, unlike bitmap images, do not store Values, typically letters or numbers. about each individual pixel. For a large illustration, such as a poster, a vector graphic would have a significantly smaller file size compared to a An image made up of pixels. This type of image loses quality if its width and/or height are increased. image.
- Scalable - when you resize a vector graphic the mathematical relationships mean that the image does not lose quality. A vector graphic the size of a postage stamp could be resized to be used on a poster and the image would still be clear.
Disadvantage
Vector graphics are never going to be as lifelike as bitmaps or photos. They will always appear computer generated.
