ResizeRegionCommand Constructor(Int32,ResizeRegionCommandType,Boolean)

Leadtools.ImageProcessing.Effects Namespace > ResizeRegionCommand Class > ResizeRegionCommand Constructor : ResizeRegionCommand Constructor(Int32,ResizeRegionCommandType,Boolean)



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.
Initializes a new ResizeRegionCommand class object with explicit parameters.

Syntax

Visual Basic (Declaration) 
Public Function New( _
   ByVal dimension As Integer, _
   ByVal type As ResizeRegionCommandType, _
   ByVal asFrame As Boolean _
)
Visual Basic (Usage)Copy Code
Dim dimension As Integer
Dim type As ResizeRegionCommandType
Dim asFrame As Boolean
 
Dim instance As ResizeRegionCommand(dimension, type, asFrame)
C# 
public ResizeRegionCommand( 
   int dimension,
   ResizeRegionCommandType type,
   bool asFrame
)
C++/CLI 
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.

Example

Run the ResizeRegionCommand on an image.
