For each edge in both polygons, check if it can be used as a separating line. If so, you are done: No intersection. If no separation line was found, you have an intersection. /// Checks if the two polygons are intersecting. bool IsPolygonsIntersecting(Polygon a, Polygon b) { foreach (var polygon in new[] { a, b … Read more
Using Rect you define its edges using integers and using RectF they are defined as floats. Looking at them more carefully I have spotted a few differences actually. I will only list what one implementation has more compared to the other one. Rect equals(Object obj) (for some reason it has its own implementation of equals) … Read more
This is not possible. If you want to display text inside a rect element you should put them both in a group with the text element coming after the rect element ( so it appears on top ). <svg xmlns=”http://www.w3.org/2000/svg”> <g> <rect x=”0″ y=”0″ width=”100″ height=”100″ fill=”red”></rect> <text x=”0″ y=”50″ font-family=”Verdana” font-size=”35″ fill=”blue”>Hello</text> </g> </svg>
