Dear sir:
      1. After exporting my DrawingDocument to a wmf file, but when I view it in a image viewer software, it just look like a bitmap file.
     
     2. And if I change the export file size, the output Image did not strech the Image in the region, Could I set the Image strech in the region,when I change the filesize much bigger. The image preview is in the attached file.
     3. How could I export the DrawingDocument to a bitmap and keep the zoom effect, when I zoom it in 3 or 5 times?
     Could you please help us to reach this.
    Regards,
    Bob
