LayoutPath (Java Platform SE 7 )

java.lang.Object
- java.awt.font.LayoutPath

```
public abstract class LayoutPath
extends Object
```
LayoutPath provides a mapping between locations relative to the baseline and points in user space. Locations consist of an advance along the baseline, and an offset perpendicular to the baseline at the advance. Positive values along the perpendicular are in the direction that is 90 degrees clockwise from the baseline vector. Locations are represented as a Point2D, where x is the advance and y is the offset.

  - pointToPath
```
public abstract boolean pointToPath(Point2D point,
                  Point2D ___location)
```
    Convert a point in user space to a ___location relative to the path. The ___location is chosen so as to minimize the distance from the point to the path (e.g., the magnitude of the offset will be smallest). If there is more than one such ___location, the ___location with the smallest advance is chosen.
    
    Parameters:
    point - the point to convert. If it is not the same object as ___location, point will remain unmodified by this call.
    ___location - a Point2D to hold the returned ___location. It can be the same object as point.
    
    Returns:
    true if the point is associated with the portion of the path preceding the ___location, false if it is associated with the portion following. The default, if the ___location is not at a break or sharp bend in the path, is to return true.
    
    Throws:
    
    NullPointerException - if point or ___location is null

  - pathToPoint
```
public abstract void pathToPoint(Point2D ___location,
               boolean preceding,
               Point2D point)
```
    Convert a ___location relative to the path to a point in user coordinates. The path might bend abruptly or be disjoint at the ___location's advance. If this is the case, the value of 'preceding' is used to disambiguate the portion of the path whose ___location and slope is to be used to interpret the offset.
    
    Parameters:
    ___location - a Point2D representing the advance (in x) and offset (in y) of a ___location relative to the path. If ___location is not the same object as point, ___location will remain unmodified by this call.
    preceding - if true, the portion preceding the advance should be used, if false the portion after should be used. This has no effect if the path does not break or bend sharply at the advance.
    point - a Point2D to hold the returned point. It can be the same object as ___location.
    
    Throws:
    
    NullPointerException - if ___location or point is null
