		double pixel2Coord(
double
$pixelPos, double
$pixelMax, double
$geoMin, double
$geoMax, boolean
$inversePix)
    

    


	
		Computes pixel to geographical coordinates transformation

    return:  geographical coordinate
  

  

    static:  
  

  

    access:  private
  










        
Parameters:

    

    

          

        double  
        $pixelPos  
        pixel coordinate
      

          

        double  
        $pixelMax  
        maximum pixel coordinate
      

          

        double  
        $geoMin  
        minimum geographical coordinate
      

          

        double  
        $geoMax  
        maximum geographical coordinate
      

          

        boolean  
        $inversePix

method point2Coords [line 63]

	

    

    

		Point point2Coords(
Point
$pixelPoint, Dimension
$imageSize, Bbox
$bbox)
    

    


	
		Converts a point coordinates from pixel to geographical.

Pixel coordinates have their origin on image top left. x grows positively  from left to right, and y grows from top to bottom.
