栅格数据另存有两种方式：①利用ISaveAs和ISaveAs2接口 ②利用GP工具另存

Dataset SaveAs (string Name,IWorkspace Workspace,string Format);

本人亲测经验：保存的路径中不要有中文字符，grid格式遇到中文字符就一个字坑坑坑，之前用给grid格式的数据修改投影也是因为中文字的问题修改失败。

1.参数Name注意事项

1）字符数不能超过13个 

2）可以包含a-z  ，A-Z ，0-9  ，“-”“_”.  (这个都是一样)

3）必须以字母开头

2.传一个输出路径的工作空间即可 （RasterWorkspace)

//去黑边
IRasterProps pRasterProps=pRaster as IRasterProps;
pRasterProps.NoDataValue=255;
//另存输出
ISaveAs2 pSaveAs = pRaster as ISaveAs2;
if (!pSaveAs.CanSaveAs(sFormat))
{
	XtraMessageBox.Show("不支持指定像素类型或文件格式的输出", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
	return ;
}
IWorkspaceFactory worksapceFactory = new RasterWorkspaceFactoryClass();
workspace = worksapceFactory.OpenFromFile(System.IO.Path.GetDirectoryName(m_sOutputPath), 0);
IDataset dataset = pSaveAs.SaveAs(System.IO.Path.GetFileName(m_sOutputPath), workspace, sFormat);
