Class: oContour

Extends

• $.oStroke

Members

readonlybounds$.oBox

The bounding box of the contour.

closedbool

wether the stroke is a closed shape.

fill$.oFillStyle

The information about the fill of this contour

indexint

The index of the stroke in the shape

readonlypathArray.<$.oVertex>

The $.oVertex (including bezier handles) making up the complete path of the stroke.

readonlypointsArray.<$.oVertex>

The oVertex that are on the stroke (Bezier handles exluded.) The first is repeated at the last position when the stroke is closed.

readonlysegmentsArray.<Array.<$.oVertex>>

The segments making up the stroke. Each segment is a slice of the path, starting and stopping with oVertex present on the curve, and includes the bezier handles oVertex.

style$.oLineStyle

The style of the stroke. null if the stroke is invisible

Methods

inherited addPoints(pointsToAdd){Array.<$.oVertex>}

openHarmony/openHarmony_drawing.js, line 1699

Adds points on the stroke without moving them, at the distance specified (0=start vertice, 1=end vertice)

Name	Type	Description
pointsToAdd	Array.<float>	an array of float value between 0 and the number of current points on the curve

Returns:

Type	Description
Array.<$.oVertex>	the points that were created (if points already existed, they will be returned)

Example

// get the selected stroke and create points where it intersects with the other two strokes
var sel = $.scn.activeDrawing.selectedStrokes[0];

var intersections = sel.getIntersections();

// get the two intersections
var intersection1 = intersections[0];
var intersection2 = intersections[1];

// add the points at the intersections on the intersecting strokes
intersection1.stroke.addPoints([intersection1.strokePoint]);
intersection2.stroke.addPoints([intersection2.strokePoint]);

// add the points on the stroke
sel.addPoints([intersection1.ownPoint, intersection2.ownPoint]);

inherited getClosestPoint(point){$.oPoint}

openHarmony/openHarmony_drawing.js, line 1797

projects a point onto a stroke and returns the closest point belonging to the stroke. Only works until a distance of 600 drawing vector units.

Name	Type	Description
point	$.oPoint

Returns:

Type	Description
$.oPoint

inherited getIntersections(stroke){Array.<Object>}

openHarmony/openHarmony_drawing.js, line 1646

The intersections on this stroke. Each intersection is an object with stroke ($.oStroke), point($.oPoint), strokePoint(float) and ownPoint(float) One of these objects describes an intersection by giving the stroke it intersects with, the coordinates of the intersection and two values which represent the place on the stroke at which the point is placed, with a value between 0 (start) and 1(end)

Name	Type	Description
stroke	$.oStroke	optional Specify a stroke to find intersections specific to it. If no stroke is specified,

Returns:

Type	Description
Array.<Object>

Example

// get the selected strokes on the active drawing
var sel = $.scn.activeDrawing.selectedStrokes;

for (var i in sel){
  // get intersections with all other elements of the drawing
	var intersections = sel[i].getIntersections();

  for (var j in intersections){
    log("intersection : " + j);
    log("point : " + intersections[j].point);                    // the point coordinates
    log("strokes index : " + intersections[j].stroke.index);     // the index of the intersecting strokes in their own shape
    log("own point : " + intersections[j].ownPoint);             // how far the intersection is on the stroke itself
    log("stroke point : " + intersections[j].strokePoint);       // how far the intersection is on the intersecting stroke
  }
}

inherited getPointCoordinates(position){$.oPoint}

openHarmony/openHarmony_drawing.js, line 1780

Get the coordinates of the point on the stroke from its strokePosition (@see $.oVertex#strokePosition). Only works until a distance of 600 drawing vector units.

Name	Type	Description
position	float

Returns:

Type	Description
$.oPoint	an oPoint object containing the coordinates.

inherited getPointDistance(point){float}

openHarmony/openHarmony_drawing.js, line 1817

projects a point onto a stroke and returns the distance between the point and the stroke. Only works until a distance of 600 drawing vector units.

Name	Type	Description
point	$.oPoint

Returns:

Type	Description
float

inherited getPointPosition(point){float}

openHarmony/openHarmony_drawing.js, line 1762

Gets the closest position of the point on the stroke (float value) from a point with x and y coordinates.

Name	Type	Description
point	oPoint

Returns:

Type	Description
float	the strokePosition of the point on the stroke (@see $.oVertex#strokePosition)

inherited updateDefinition(){object}

openHarmony/openHarmony_drawing.js, line 1745

fetch the stroke information again to update it after modifications.

Returns:

Type	Description
object	the data definition of the stroke, for internal use.
