我正在开发一个使用unfoldingmaps进行处理的应用程序.

下面是处理中展开的示例代码

import de.fhpotsdam.unfolding.*;
import de.fhpotsdam.unfolding.geo.*;
import de.fhpotsdam.unfolding.utils.*; 

UnfoldingMap map;

void setup() {
    size(800, 600, P2D);
    map = new UnfoldingMap(this);
    MapUtils.createDefaultEventDispatcher(this, map);
}

void draw() {
    map.draw();
}

这是我收到的错误消息
