Method Summary

Modifier and Type	Method	Description
protected static ArrayList<Point2D>	expandPolygon(ArrayList<Point2D> pts, double expand)	Assumes a convex polygon for the clipping area.
protected static ArrayList<Point2D>	expandPolygon2(ArrayList<Point2D> pts, double expandX, double expandY)	use cheap algorithm to expand polygons, works best on regular 4+ sided convex polygons used primarily for expanding the original clipping areas.
protected static double	getZoomFactor(Rectangle2D rect, ArrayList<Point2D> clipPoints, ArrayList<POINT2> pixels)	Use clipping rectangle or clip points to build a zoom factor if the client zoomed in after the initial render.
protected static void	removeTrailingPoints(TGLight tg, Object clipArea)	removes leading or trailing segments after the points were clipped
protected static boolean	segmentColorsSet(TGLight tg)	returns true if segment data set for MSR, ASR, Boundary
protected static void	SetShapeInfosPolylines(TGLight tg, ArrayList<ShapeInfo> shapeInfos, Object clipBounds)
protected static void	setSplineLinetype(TGLight tg)

Method Details

setSplineLinetype

protected static void setSplineLinetype(TGLight tg)

SetShapeInfosPolylines

protected static void SetShapeInfosPolylines(TGLight tg,
 ArrayList<ShapeInfo> shapeInfos,
 Object clipBounds)

expandPolygon

protected static ArrayList<Point2D> expandPolygon(ArrayList<Point2D> pts,
 double expand)

Assumes a convex polygon for the clipping area. expand the polygon using pixels and a similar algorithm to what flash renderer does for DEPTH AREA

Parameters:

pts - clipping area to expand

expand - pixels expansion

Returns:

expandPolygon2

protected static ArrayList<Point2D> expandPolygon2(ArrayList<Point2D> pts,
 double expandX,
 double expandY)

use cheap algorithm to expand polygons, works best on regular 4+ sided convex polygons used primarily for expanding the original clipping areas. After clipping a tactical line against the expanded clipping area, the original clipping area can be used to drop the clip lines

Parameters:

pts - points to expand, usually a clipping area

expandX - X expansion factor, e.g 10% growth would be 1.1

expandY - Y expansion factor

Returns:

points for the expanded polygon

removeTrailingPoints

protected static void removeTrailingPoints(TGLight tg,
 Object clipArea)

removes leading or trailing segments after the points were clipped

Parameters:

tg -

clipArea -

segmentColorsSet

protected static boolean segmentColorsSet(TGLight tg)

returns true if segment data set for MSR, ASR, Boundary

Parameters:

tg -

Returns:

getZoomFactor

protected static double getZoomFactor(Rectangle2D rect,
 ArrayList<Point2D> clipPoints,
 ArrayList<POINT2> pixels)

Use clipping rectangle or clip points to build a zoom factor if the client zoomed in after the initial render. Multiply the geo segmenting interval by this factor.

Parameters:

rect -

clipPoints -

pixels -

Returns:
