Performs a hit test on a Bezier spline. This works with any number of control points, by fitting Bezier splines smoothly together.

Parameters:

point - The point to test.

pts - The control points of the spline with untransformed coordinates.

length - The number of significant points in pts.

ghosting - true if the line is drawn during ghosting that happens during interactive spline creation. In this case, it is unknown how many control points the user will add later; therefore, the spline drawing is optimized under the assumption that the user will add more control points.

smoothness - The smoothness of a multipoint spline (between 0 and 1).

lineWidth - The width of the pen used to draw the spline.

lineJoin - The 'line join' style used to draw the spline. The valid values are defined in the interface IlvStroke.

endCap - The 'end cap' style used to draw the spline. The valid values are defined in the interface IlvStroke.

t - The transformer used to draw the spline.

Returns:

true if the point is on the Bezier spline, false otherwise.

length - The number of significant points in bendpoints.

smoothness - The smoothness of a multipoint spline (between 0 and 1).

ghosting - true if the line is drawn during ghosting that happens during interactive spline creation. In this case, it is unknown how many control points the user will add later; therefore, the spline drawing is optimized assuming that the user will add more control points.

The number of handle points is always the same as the number of user control points.

Parameters:

handleIndex - The index of the handle.

bendpoints - The user control points.

length - The number of significant points in bendpoints.

smoothness - The smoothness of a multipoint spline (between 0 and 1).

ghosting - true if the line is drawn during ghosting that happens during interactive spline creation. In this case, it is unknown how many control points the user will add later; therefore, the spline drawing is optimized assuming that the user will add more control points.

                                                     boolean ghosting)

Returns the used control point from the handle position on a smooth spline. This is the inverse operation to GetSmoothSplineHandleFromBend(int, ilog.views.IlvPoint[], int, double, boolean). The number of handle points is always the same as the number of user control points.

Parameters:

handleIndex - The index of the handle.

handlePoint - The position of the handle on the spline.

bendpoints - The user control points.

length - The number of significant points in bendpoints.

smoothness - The smoothness of a multipoint spline (between 0 and 1).

ghosting - true if the line is drawn during ghosting that happens during interactive spline creation. In this case, it is unknown how many control points the user will add later; therefore, the spline drawing is optimized assuming that the user will add more control points.

                                             int[] resultingLength)

Returns an array of IlvPoints for a smooth spline from an array of IlvPoints of user control points. If required space is available in the bezierpoints array, the method uses it. This method analyzes the control points to calculate an appropriate smoothness automatically. The number of significant points in the resulting array depends on the position of the control points. The algorithm needs an auxiliary integer array of the size length. If an array flags of size length is passed, this array is used as auxiliary array.

Parameters:

originalpoints - The user control points.

length - The number of significant points in originalpoints.

ghosting - true if the line is drawn during ghosting that happens during interactive spline creation. In this case, it is unknown how many control points the user will add later; therefore, the spline drawing is optimized under the assumption that the user will add more control points.

bezierpoints - The returned array.

flags - An auxiliary array. Can be null.

resultingLength - An array of 1, which will receive the number of significant points in the returned array.

SetJViews60LineStyleMode

public static void SetJViews60LineStyleMode(boolean flag)

Sets the behavior of current products to JViews 6.0 line style zooming. In JViews 6.0 and prior versions, a graphic objects line style was ignored at certain zoom factors. This affects the following methods:

• DrawBezier(java.awt.Graphics, ilog.views.IlvPoint[], int, boolean, double, double, int, int, float[], ilog.views.IlvTransformer, boolean).
• DrawClosedBezier(java.awt.Graphics, ilog.views.IlvPoint[], int, boolean, double, double, int, int, float[], ilog.views.IlvTransformer).

startBidiChange

public static IlvGraphicVector startBidiChange(IlvGraphicBag bag)

Starts a session that changes either the base text direction, the locale or the component orientation of a graphic bag. It returns all graphic objects that are sensitive versus this change. This is only needed when implementing a graphic bag that has a new setter for base text direction, the locale or the component orientation. All predefined graphic objects do this already automatically. The scheme to change the base text direction, the locale or the component orientation of a graphic bag is the following:

 IlvGraphicVector v = IlvGraphicUtil.startBidiChange(bag);
 try {
   // do the change on the bag, for instance, for base text direction:
   bag._baseTextDirection = baseTextDirection;
   // or:
   bag._componentOrientation = componentOrientation;
   // or:
   bag._locale = locale;
 } finally {
   IlvGraphicUtil.stopBidiChange(bag, v, redraw);
 }
 

Parameters:

bag - The graphic bag

Stops a session that changes either the base text direction, the locale or the component orientation of a graphic bag.
