我收集了一些形状。
public List _shapes=新建列表();
然后我想做的是调整所有形状的位置(x,y)在它里面,当我规模的三角形。这是第一张图片:
if(rb_Both.Checked)
{
tbox_Width.Text = scaledSize.ToString();
//Updates both width and height, x-axis and y-axis while scaling
triangleWidth = (float)(((Convert.ToInt32(tbox_Width.Text)) * 96) / 25.4);
triangleHeight = ((float)((triangleWidth * (Math.Sqrt(3))) / 2));
tX = (s.center.X - (triangleWidth / 2f)) - 0.5f;
tY = (s.center.Y + (triangleHeight / 3));
trackBar_Size.Maximum = maximumValue;
}
//Adjusts the center of the triangle while it is scaled up
if (s.tPoints[2].Y <= 15)
{
s.x = (s.center.X - (w / 2));
s.y = (s.center.Y - (h / 2));
s.center.Y = 250 + (((Convert.ToInt32(tbox_Width.Text)) - 110) * 2);
}
else if (Convert.ToInt32(tbox_Width.Text) <= 114)
s.center.Y = 250;
break;
