AddPolyHatch(object[], object[], bool, object)

Adds a new vdPolyhatch in the document.

public object AddPolyHatch(object[] curves, object[] outlines, bool drawit, object entities)

Parameters

curves object[]

An array of vdfigures that they will be hatched or an array of points.

outlines object[]

Used for DrawBoundary property.An array of vdfigures or an array of points or null in order to use the outlines of the objects.

drawit bool

Defines if the vdPolyhatch object will be drawn.

entities object

The entities collection where the polyhatch will be added. This can be the entities of layout or a block.

Returns

object

Examples

Example1: In the first example we create a new polyline,arc,rectangle,circle and ellipse and then we will add them in the AddPolyhatch method. We do not set any outlines so the outlines of the objects will be used.

var circle = vdcanvas.AddCircle([-3, -3, 0], 1, false);
var rect = vdcanvas.AddRect([-7, 6, 0], [-1, 10, 0], false);
var arc = vdcanvas.AddArc(vdgeo.newpoint(-20, 0, 0), 5, vdgeo.DegreesToRadians(0), vdgeo.DegreesToRadians(135), false);
var ellipse = vdcanvas.AddEllipse(vdgeo.newpoint(10, 10, 0), 10, 4, vdgeo.DegreesToRadians(90), vdgeo.DegreesToRadians(0), vdgeo.DegreesToRadians(360), false);
var vertexes = [vdgeo.newvertex(-2, -2, 0, 0), vdgeo.newvertex(2, 1, 0, 0), vdgeo.newvertex(5, 5, 0, 0), vdgeo.newvertex(2, 3, 0, 0)];
var pline = vdcanvas.AddPolyline(vertexes, false);
pline.SPlineFlag = 0;// standad polyline
pline.Flag = 1;// closed polyline.By default Flag = 0 which is not be closed.
vdcanvas.UpdateFig(pline);//update the figure in order to get the changes
         var ph = vdcanvas.AddPolyHatch([arc, ellipse, circle, pline, rect], null, true);          
         ph.HatchProperties = vdcanvas.createNewHatchProperties("u20", vdConst.colorFromString("255,255,0,255"), vdConst.colorFromString("255,0,0,255"), 1.0, 0.0);
         ph.HatchProperties.DrawBoundary = true;//By default is false so the boundary is not be drawn
         vdcanvas.UpdateFig(ph);//update the figure in order to get the changes
         vdcanvas.DrawEntity(ph);// draw the figure on the screen</code></pre>

Example2: In the second example we create an array of eight points which represent two rectangles and then we will add them in the AddPolyhatch method. We now set outlines the same points of the rectangles.

var a1, a2, a3, a4, b1, b2, b3, b4; //create the new eight variables
         a1 = [0, 0, 0]; // set values for the first rectangle
         a2 = [1, 0, 0];
         a3 = [1, 1, 0];
         a4 = [0, 1, 0];

         b1 = [2, 0, 0]; // set values for the second rectangle
         b2 = [3, 0, 0];
         b3 = [3, 1, 0];
         b4 = [2, 1, 0];

         vdcanvas.SetActiveHatchProperties(vdcanvas.createNewHatchProperties('solid', vdConst.colorFromString("255,0,0"), vdConst.colorFromString("0,0,255")))//set active hatch properties      
         var ph = vdcanvas.AddPolyHatch([[a1, a2, a3, a4], [b1, b2, b3, b4]], [[a1, a2, a3, a4], [b1, b2, b3, b4]], true);
         ph.HatchProperties.DrawBoundary = true; //By default is false so the boundary is not be drawn
         vdcanvas.DrawEntity(ph); // draw the figure on the screen</code></pre>
