Vector graphics are composed of paths. It is the use of polygons to represent images in computer graphics.
- Vector is a representation of both a quantity and a direction at the same time.
- Vector graphics is the creation of digital images through a sequence of commands that place lines and shapes in a given two-dimensional or three-dimensional space.
Vector operations
- Vector graphics editors allow rotation, movement, mirroring, stretching, skewing, affine transformations, changing of z-order and combination of primitives into more complex objects.
- More sophisticated transformations include set operations on closed shapes (union, difference, intersection, etc.).
- Vector graphics are ideal for simple or composite drawings that need to be device-independent, or do not need to achieve photo-realism. For example, the PostScript and PDF page description languages use a vector graphics model.
Advantages of vector images:
The important point of vector graphics is the power of scalability
The important point of vector graphics is the power of scalability
- Vector objects are much smaller than other image format.
- Data can be represented in original resolution without generalization.
- Graphical outputs of the images are more pleasing than the created as raster image.
- In some data like hard copy maps, no data conversion is needed.
