How to detect the center line of a canvas to center an object when it has dragged?
advertisements
This question belongs to fabricJS and canvas.When I dragged a object to a canvas I need to detect center line and snap to it. I found some similar approach in this question. But it deals with div elements. I need to deal with center line of the canvas. How I do this?
You can define snap functionality manually with moving option. Try following.
'object:moving' : function(e){
var objCenter = e.target.getLeft() + (e.target.getWidth()/2);
var targetLine = canvas.left+(canvas.width/2);
if(objCenter > targetLine-10 && objCenter < targetLine+10){
e.target.left = targetLine - (e.target.getWidth()/2) ;
}else{
e.target.setOpacity(1);
}
