Method Detail

getRealWorldUnits

public final String getRealWorldUnits()

Gets the real-world scale units. String label that indicates the unit of measure that scale represents when measuring a single logical coordinate.

 Gets the real-world scale units.
  string file = "ExampleFile.dwf";
 using (FileStream inStream = new FileStream(file, FileMode.Open))
 using (DwfImage image = (DwfImage)Image.Load(inStream))
 {
     DwfPageEPlot page = image.Pages[0] as DwfPageEPlot;
     if (page != null)
     {
         string unitsName =page.RealWorldUnits;
     }
 }

Returns:: The the real-world scale units or empty string, if the unit name is not specified or resource does not contain the 'Units' operand.

getRealWorldMaxPoint

public final Cad3DPoint getRealWorldMaxPoint()

Gets the maximum value of entities coordinates scaled to real-world units.

 Gets width and height of image scaled to real-world units.
  string file = "ExampleFile.dwf";
 using (FileStream inStream = new FileStream(file, FileMode.Open))
 using (DwfImage image = (DwfImage)Image.Load(inStream))
 {
     DwfPageEPlot page = image.Pages[0] as DwfPageEPlot;
     if (page != null)
     {
         Cad3DPoint maxPoint = page.RealWorldMaxPoint;
         Cad3DPoint minPoint = page.RealWorldMinPoint;
         double width = maxPoint.X - minPoint.X;
         double height = maxPoint.Y - minPoint.Y;
     }
 }

Returns:: The maximum value of entities coordinates scaled to real-world units or 'null' value, if resource does not contain the 'Units' operand.

getDrawObjectsInRealWorldCoordinates

public final DwfWhipDrawable[] getDrawObjectsInRealWorldCoordinates()

Gets the collection of entities scaled to real-world units from resource with role '2d streaming graphics'.

  Retrieves the collection of entities scaled to real-world units.
    string file = "ExampleFile.dwf";
  DwfWhipDrawable[] result;
  using (FileStream inStream = new FileStream(file, FileMode.Open))
  using (DwfImage image = (DwfImage)Image.Load(inStream))
  {
      DwfPageEPlot page = image.Pages[0] as DwfPageEPlot;
      if (page != null)
      {
          result = page.DrawObjectsInRealWorldCoordinates;
      }
  }
  foreach (DwfWhipDrawable s in result)
  {
      Do something;
  }

Returns:: The collection of entities scaled to real-world units or 'null' value, if resource does not contain the 'Units' operand.

getRealWorldMinPoint

public final Cad3DPoint getRealWorldMinPoint()

Gets the minimum value of entities coordinates scaled to real-world units.

 Gets width and height of image scaled to real-world units.
  string file = "ExampleFile.dwf";
 using (FileStream inStream = new FileStream(file, FileMode.Open))
 using (DwfImage image = (DwfImage)Image.Load(inStream))
 {
     DwfPageEPlot page = image.Pages[0] as DwfPageEPlot;
     if (page != null)
     {
         Cad3DPoint maxPoint = page.RealWorldMaxPoint;
         Cad3DPoint minPoint = page.RealWorldMinPoint;
         double width = maxPoint.X - minPoint.X;
         double height = maxPoint.Y - minPoint.Y;
     }
 }

Returns:: The minimum value of entities coordinates scaled to real-world units or 'null' value, if resource does not contain the 'Units' operand.
