AO——将函数栅格数据集保存到磁盘

// 创建栅格工作空间.
IWorkspaceFactory workspaceFactory=new RasterWorkspaceFactory();
// 打开指向输入文件夹的工作空间.
IWorkspace workspace=workspaceFactory.OpenFromFile(@"c:\FRDs", 0);
IRasterWorkspace rasterWorkspace=(IRasterWorkspace)workspace;
// 打开.afr 文件为栅格数据集.
IRasterDataset myRasterDataset=rasterWorkspace.OpenRasterDataset(
    "CompositeBand.afr");
// 打开指向输出文件夹的工作空间.
IWorkspace outputWorkspace=workspaceFactory.OpenFromFile(@"c:\temp", 0);
// 使用 SaveAs 接口将栅格数据集转换为 ISaveAs 对象.
ISaveAs saveAsRaster=(ISaveAs)myRasterDataset;
// 使用SaveAs方法保存为指定格式的栅格数据集.
saveAsRaster.SaveAs("outputFile.tif", outputWorkspace, "tiff");
