GlyphFactory (Geotools modules 21.0 API)

All Known Implementing Classes:

DefaultGlyphFactory
```
public interface GlyphFactory
```
Used to draw the little pictures that appear in a Legend.
We are making this an interface so that applications can implement their own icons as needed.

- Method Detail
  - point
```
Icon point(Color point,
           Color fill)
```
    Produce a simple Icon representing a point.
    
    Parameters:
    
    point - Color of the Point
    
    fill - Color inside the Point
    
    Returns:
    
    Icon representing a Point
  - point
```
Icon point(Rule rule)
```
    Produce a simple Icon representing a point.
    At a minimum this code is the same as:
```
 PointSymbolizer symbolizer = SLD.pointSymbolizer( rule );
 return glyphFactory.point( SLD.pointColor( symbolizer ), SLD.fillColor( symbolizer ) );
 
```
    Implementations have the option of going into greater detail, picking up on TextSymbolizers and so on.
    Parameters:
    
    rule - Rule used to render a Point
    
    Returns:
    
    Icon representing a Point
  - line
```
Icon line(Color line,
          int width)
```
    Produces a simple Icon representing a line.
    
    Parameters:
    
    line - Line colour
    
    width - Line width
    
    Returns:
  - line
```
Icon line(Rule rule)
```
    Produce a simple Icon representing a point.
    At a minimum this code is the same as:
```
 LineSymbolizer symbolizer = SLD.lineSymbolizer( rule );
 return glyphFactory.point( SLD.lineColor( symbolizer ), SLD.lineWidth( symbolizer ) );
 
```
    Implementations have the option of going into greater detail, picking up on TextSymbolizers and so on.
    Parameters:
    
    rule - Rule used to render a Point
    
    Returns:

  - geometry
```
Icon geometry(Color color,
              Color fill)
```
  - geometry
```
Icon geometry(Rule rule)
```
  - polygon
```
Icon polygon(Color color,
             Color fill,
             int width)
```
  - polygon
```

          Color color2,
          Color color3,
          Color color4)
```
  - swatch
```
Icon swatch(Color color)
```
  - palette
```
Icon palette(Color[] colors)
```
  - icon
```
Icon icon(SimpleFeatureType schema)
```
    Make a basic representation of the provided FeatureType.
    
    Parameters:
    
    schema -
    
    Returns:
  - icon
```
Icon icon(MapLayer layer)
```
    Glyph for the provided layer.
    At a minimum the icon will be based on:
    - layer schema, will be considered a generic geometry if not recognized
    - layer style, defaults will be used if not recognized
    Parameters:
    
    layer -
