Я пытаюсь изменить размер прямоугольника в paper.js.Я могу сделать это для более старых версий paperjs (например, 0.9.25), но это не работает для последней версии 0.11.8.Я не уверен, почему это происходит, любая помощь будет высоко оценена.
Вот ссылка Sketch, вы можете выбрать версию 0.9.25, где она работает, и 0.11.8, где она не работает.

Вот мой код:

fillColor: 'green',
strokeColor: 'black'

var segment, path, hitType;
var clickPos = null;
var movePath = false;
var minHeight = 1;
var minWidth = 1;
function onMouseDown(event) {
segment = path = null;
var hitResult = project.hitTest(event.point, hitOptions);
if (!hitResult)
return;
hitType = hitResult.type;
if (event.modifiers.shift) {
if (hitResult.type == 'segment') {
hitResult.segment.remove();
