public ResizeRegionCommand( 
   int dimension,
   ResizeRegionCommandType type,
   bool asFrame
)

'Declaration
 
Public Function New( _
   ByVal dimension As Integer, _
   ByVal type As ResizeRegionCommandType, _
   ByVal asFrame As Boolean _
)

'Usage
 
Dim dimension As Integer
Dim type As ResizeRegionCommandType
Dim asFrame As Boolean
 
Dim instance As New ResizeRegionCommand(dimension, type, asFrame)

public ResizeRegionCommand( 
   int dimension,
   ResizeRegionCommandType type,
   bool asFrame
)

function ResizeRegionCommand( 
   dimension ,
   type ,
   asFrame 
)

public:
ResizeRegionCommand( 
   int dimension,
   ResizeRegionCommandType type,
   bool asFrame
)

Parameters

dimension: Number of pixels by which to resize the region. This parameter only accepts positive values.
type: Value that indicates whether to contract or expand the image region.
asFrame: Value that indicates whether to create a frame associated with the resized image region. If this parameter is true, then the command creates a frame of thickness "dimension" for the resized region. If the type parameter is ResizeRegionCommandType.ExpandRegion, the frame created will exist outside the boundaries of the resized region. If the type parameter is ResizeRegionCommandType.ContractRegion, the frame will be within the boundaries of the resized region. If this parameter is false then the command resizes the region only, and does not create a frame.
