展開 SimpleMapApp - 圖像文件丟失

Question

我正在開發一個使用展開圖進行處理的應用程序。

以下是處理中展開的示例代碼

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();
}

這是我收到的錯誤消息

我嘗試從瀏覽器點擊 url - 它說圖像文件已被移動。 我應該在本地系統中轉儲這個嗎？ 這是如何運作的？ 這些 URL 是否適用於使用展開的其他人？

這是示例代碼的修改版本。

import processing.core.PApplet;
import de.fhpotsdam.unfolding.UnfoldingMap;
import de.fhpotsdam.unfolding.geo.Location;
import de.fhpotsdam.unfolding.utils.MapUtils;
import de.fhpotsdam.unfolding.providers.Google;
public class HelloUnfoldingWorld extends PApplet {

    UnfoldingMap map;

    public void setup() {
        size(800, 600, OPENGL);

        map = new UnfoldingMap(this, new Google.GoogleMapProvider());
        map.zoomAndPanTo(10, new Location(52.5f, 13.4f));

        MapUtils.createDefaultEventDispatcher(this, map);
    }

    public void draw() {
        background(0);
        map.draw();
    }

}

我已經添加了

import de.fhpotsdam.unfolding.providers.Google;

並修改

map = new UnfoldingMap(this, new Google.GoogleMapProvider());

現在它正在工作

幾個星期以來，默認使用的地圖圖塊服務 Unfolding 在移至 WikiMedia Labs 時沒有正確響應。 現在它重定向，並再次提供瓷磚圖像。
