我的地图在OL3中看起来很怪异并且“像素化”

Question

我试图用OL3呈现一个地图服务器，它不能正常工作。地图服务器的文档不存在，并且地图服务器的GetCapabilities以非常短（不太好或有用）的答案作出响应。

我已设法展示地图，但它看起来非常奇怪，非常像。一张图片说的话超过了千言万语，所以我只会告诉你它的外观。

我甚至做了一个JS小提琴：

http://jsfiddle.net/qpz7bp2g/

var oLayers = "ST:background";

    var oURL = "its on the jsfiddle";

    var oProjection = "EPSG:3006";

    var oScales = [4000,8000,15000,30000,90000, 120000, 180000, 250000, 500000];

    var screenDPI = 95;
    var IPM = 39.37;

    var resolutions = [];
    for (var i = oScales.length-1; i >= 0;--i) {
        resolutions.push(oScales[i] / (screenDPI * IPM));
    }

    var extent=[181896.33,6101648.07,864582.51,7688373.92];

    var projection = new ol.proj.Projection({
        code: oProjection,
        units: "m",
        extent: extent
    });

    //ol.proj.addProjection(projection);

    var layers = [
        new ol.layer.Tile({
            extent: extent,
            source: new ol.source.TileWMS({
                url: oURL,
                params: {'LAYERS':oLayers,
                'SRS' : "EPSG:3006"}
            })
        })
    ];


    var view = new ol.View({
        projection: projection,
        center: ol.proj.transform([13.0, 55.6], 'EPSG:4326', oProjection),
        resolutions: resolutions,
        extent: extent,
        zoom: 0
    });

    var map = new ol.Map({
        layers: layers,
        target: 'maps',
        view: view
    });

有什么想法吗？

WMS GetMap网址看起来不错：

http://gis.skanetrafiken.se/wmspublic/service/wms?
SERVICE=WMS&
VERSION=1.3.0&
REQUEST=GetMap&
FORMAT=image%2Fpng&
TRANSPARENT=true&
LAYERS=ST%3Abackground&
SRS=EPSG%3A3006&
WIDTH=640&
HEIGHT=640&

但这就是WMS服务器呈现的内容：

所以我猜问题不是OL而是服务器上的样式配置。或许您可能需要找出合适的缩放级别。使用相同的WMS服务器是否有一个工作和良好的解决方案？检查它们的缩放级别。
