- Method Detail
  - size
```
int size()
```
    Returns the number of coordinates for this shape. Can be used to iterate over all coordinates for this shape (e.g. for drawing the shape). Example:
```
 for (int i = 0; i < myShape.size(); i++) {
        PVector p = myShape.get(i);
 }
 
```
    Returns:
    
    The number of coordinates for this shape.
  - get
```
processing.core.PVector get(int i)
```
    Returns the coordinate with index i. Please make sure i is within bounds, e.g. using the size() method. Example:
```
 for (int i = 0; i < myShape.size(); i++) {
        PVector p = myShape.get(i);
 }
 
```
    Parameters:
    
    i - The index of a coordinates of this shape.

    The coordinate of the shape with the given index.
  - getStart

    The x-position start coordinate for the shape.
