      EnumValue
      get
      imageStretch
      
    
    
Gets or sets how the Picture's image is stretched within its bounding box. Some images will be a different aspect ratio than their given size or #desiredSize. This property will never change the size of the Picture itself, only the size of the image that is drawn in the Picture's #actualBounds.
Possible values are GraphObject.Fill, GraphObject.Uniform, GraphObject.UniformToFill, and GraphObject.None. The default is GraphObject.Fill.
