瓦片(tileImage)
POST
/rest/services/{servicename}/image/tileImage
获取影像集的瓦片图片。默认返回的图片的格式是 PNG。
将出的完整的影像集图片以像素为单位切割成多个相同大小的格网，那么地图就可以由多个小块拼合而成。tileImage 资源表示的就是这些地图的小块，通过该接口服务，可以获取地图（{mapName}）中相应的格网图片，可以设置一些定制输出图片的参数，如设置出图的图层、图片大小、格网行列号、地图是否透明、动态投影的目标投影等。
格网的划分规则如下：将地图全幅显示时的图片从左上角开始，往下和往右进行切割，切割的大小默认为 256*256 像素，左上角的格网行号为 0，列号为 0，往下和往右依次递增。其中，格网的大小和地图的比例尺等参数都可以在请求时进行指定。
支持的表述格式：PNG、BMP、GIF、JPG、WebP。
