'Declaration
 
Public Function Create( _
   ByVal Width As System.Integer, _
   ByVal Height As System.Integer _
) As System.Integer

'Usage
 
Dim instance As CiImage
Dim Width As System.Integer
Dim Height As System.Integer
Dim value As System.Integer
 
value = instance.Create(Width, Height)

public System.int Create( 
   System.int Width,
   System.int Height
)

public function Create( 
    Width: System.Integer;
    Height: System.Integer
): System.Integer;

public function Create( 
   Width : System.int,
   Height : System.int
) : System.int;

public:
System.int Create( 
   System.int Width,
   System.int Height
)

Parameters

Width: Width of the new image in pixels
Height: Height of the new image in pixels

This method creates a bi-tonal image with all pixels are set to white and resolution is 300 dpi.

Use CreateBpp to create a color or grayscale image object

This method generates an error if object.Image.IsZone is true.
