    • getCartographicLength

      public static double getCartographicLength(org.gvsig.fmap.mapcontext.rendering.symbols.CartographicSupport cartographicElement, double length, org.gvsig.fmap.mapcontext.ViewPort viewPort, double dpi)
      Calculates the distance in pixels corresponding to the provided length, according to the current rendering context (output dpi, map scale, map units) and the symbol cartographic settings (unit, size, and unit reference system).
      Parameters:
      cartographicElement - CartographicSupport object which contains the reference system and the measuring units for the provided length
      length - The length to be computed in pixels. The length is supposed to be provided in the units defined in the cartographicElement
