Drawer
public class Drawer extends Object
This class is used to isolate GeoTools from the specific graphic library being used for rendering.

  • Method Details

    • create

      public static Drawer create()
      Retrieve the default Drawing implementation.
      Returns:
      Drawing ready for use

    • drawDirect

      public void drawDirect(BufferedImage bi, SimpleFeature feature, Style style)
      Used to draw a freature directly onto the provided image.

      Feature coordintes are in the same coordinates as the image.

      You may call this method multiple times to draw several features onto the same Image (say for glyph creation).

      Parameters:
      bi - Image to render on to
      feature - Feature to be rendered
      style - Style to render feature with
