ArcGIS Engine 10 开发手册(10-3)栅格格式地图输出

栅格格式文件的输出主要是依靠 IExportImage 接口，该接口被以下 5 个类实现：

示例：根据传入的分辨率输出JPG格式

public void CreateJPEGHiResolutionFromActiveView (IActiveView pActiveView, String pFileName, Int32 pScreenResolution, Int32 pOutputResolution)

{

  ESRI.ArcGIS.Output.IExport pExport = new ESRI.ArcGIS.Output.ExportJPEGClass ();
  pExport.ExportFileName = pFileName;

  pExport.Resolution = pOutputResolution;

  ESRI.ArcGIS.Display.tagRECT pExportRECT;
  pExportRECT.left = 0;

  pExportRECT.top = 0;

  pExportRECT.right = pActiveView.ExportFrame.right * (pOutputResolution / pScreenResolution);

  pExportRECT.bottom = pActiveView.ExportFrame.bottom * (pOutputResolution / pScreenResolution);

  ESRI.ArcGIS.Geometry.IEnvelope pEnvelope = new ESRI.ArcGIS.Geometry.EnvelopeClass ();

  pEnvelope.PutCoords (pExportRECT.left, pExportRECT.top, pExportRECT.right, pExportRECT.bottom);
  pExport.PixelBounds = pEnvelope;

  System.Int32 hDC = pExport.StartExporting ();
  pActiveView.Output (hDC, (System.Int16) pExport.Resolution, ref pExportRECT, null, null);

  pExport.FinishExporting ();
  pExport.Cleanup ();

}
