Initializes a new
ResizeRegionCommand class object with explicit parameters.
Syntax
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.
