sendPointToPlane

sendPointToPlane(point, from?, to?): Point

Defined in: src/util/misc/planeChange.ts:36

Sends a point from the source coordinate plane to the destination coordinate plane.
From the canvas/viewer’s perspective the point remains unchanged.

Parameters

point

Point

from?

TMat2D = iMatrix

plane matrix containing object. Passing undefined is equivalent to passing the identity matrix, which means point exists in the canvas coordinate plane.

to?

TMat2D = iMatrix

destination plane matrix to contain object. Passing undefined means point should be sent to the canvas coordinate plane.

Returns

Point

transformed point

Example

var obj = new Rect({ left: 20, top: 20, width: 60, height: 60, strokeWidth: 0 });
var group = new Group([obj], { strokeWidth: 0 });
var sentPoint1 = sendPointToPlane(new Point(50, 50), undefined, group.calcTransformMatrix());
var sentPoint2 = sendPointToPlane(new Point(50, 50), iMatrix, group.calcTransformMatrix());
console.log(sentPoint1, sentPoint2) //  both points print (0,0) which is the center of group
