Then it's 80 % of the aspect ;-)


function ondrag(x,y,but,cmd,shift,capslock,option,ctrl)
{
	var f,a, height, width, aspect;

	height = box.rect[3] - box.rect[1];
	width = box.rect[2] - box.rect[0];
	aspect = width/height;

	aspect *= 0.8; 	// 80 % of the aspect
	
	a = sketch.screentoworld(x,y);

	//detect horizontal movement
	f = (a[0] + aspect) / (2*aspect);

	msg_float(f); //set new value with clipping + refresh
}

Cheers,
