Question

我有一个本地ArcGIS服务器9.3.1。我启用了WMS和缓存（平铺）。我想使用OpenLayers显示切片，因为ArcMap无法打开自己的REST服务;（

使用OpenLayers这很有效，除了瓷砖质量不好。航拍照片基础层（jpeg）非常像素化，叠加也很糟糕，png8。

当我查看服务器上的平铺文件夹时，我看到图像没问题，所以当OpenLayers打开它们时会出现问题。

这是我的代码：

var mapOptions = {
    projection: new OpenLayers.Projection('EPSG:28992'),
    resolutions: [3440.64, 1720.32, 860.16, 430.08, 215.04, 107.52, 53.76, 26.88, 13.44, 6.72, 3.36, 1.68, 0.84, 0.42, 0.21, 0.105, 0.0525],
    div: "map",
    maxExtent: new OpenLayers.Bounds(634.5732789819,306592.8911594,1762242.253279,2068200.5711594),
    units: "m",
    numZoomLevels: 17,
    tileSize: new OpenLayers.Size(512,512),
    controls: []};

var map = new OpenLayers.Map('map', mapOptions);

var aerial= new OpenLayers.Layer.ArcGIS93Rest("aerial",
    "http://myServer/arcgis/rest/services/myMap/MapServer/export", 
    {layers: "show:0",
      type: "jpg",
      useScales: true,
      useAGS: true,
      transparent: false
    },
    { tileSize: new OpenLayers.Size(512,512),
      buffer: 2,      
      visibility: false,        
      isBaseLayer: true,
      transitionEffect: 'resize'
    }
);                    

var tiled = new OpenLayers.Layer.ArcGIS93Rest(Tiled",
    "http://myServer/arcgis/rest/services/MyMap/MapServer/export", 
    {layers: "show:56",
      type: "png8",
      useScales: true,
      useAGS: true,
      transparent: true
    },
    { tileSize: new OpenLayers.Size(512,512),
      buffer: 0,      
      visibility: false,        
      isBaseLayer: false,
      transitionEffect: 'resize'
    }
);

边界和分辨率来自图层。有人建议如何在OpenLayers中从ArcGIS显示平铺的WMS图层吗？

感谢。

OpenLayers.Layer.ArcGIS93Rest使用质量差的图像
