- Stretch[ <Geometric Object>, <Line>, <Ratio> ]
- Stretch[ <Image>, <Line>, <Ratio> ]
- The object is stretched perpendicular to the line by the given ratio (ie points on the line aren't moved and the distance of other points from the line is multiplied by given ratio.)
- Stretch[ <Geometric Object>, <Vector> ]
- Stretch[ <Image>, <Vector> ]
- The object is stretched parallel to the given vector by the ratio given by the magnitude of the vector (ie points on the line perpendicular to the vector (through its startpoint) stay on their place and distance of other points from the line is multiplied by given ratio.)
