ScaleImage Method (CiTools)

Visual Basic
C#
Delphi
JScript
C++/CLI

'Declaration
 
Public Function ScaleImage( _
   ByVal ScaleX As System.Double, _
   ByVal ScaleY As System.Double _
) As System.Integer

'Usage
 
Dim instance As CiTools
Dim ScaleX As System.Double
Dim ScaleY As System.Double
Dim value As System.Integer
 
value = instance.ScaleImage(ScaleX, ScaleY)

public System.int ScaleImage( 
   System.double ScaleX,
   System.double ScaleY
)

public function ScaleImage( 
    ScaleX: System.Double;
    ScaleY: System.Double
): System.Integer;

public function ScaleImage( 
   ScaleX : System.double,
   ScaleY : System.double
) : System.int;

public:
System.int ScaleImage( 
   System.double ScaleX,
   System.double ScaleY
)

Parameters

ScaleX: Scale factor in horizontal direction
ScaleY: Scale factor in vertical direction

When ScaleX or ScaleY are less than 1.0 bi-tonal image is converted to grayscale before scaling. Then it is converted back to bi-tonal applying pScaleType and pScaleThreshold properties.

Image.HorzDpi and Image.VertDpi properties are multiplied by ScaleX and ScaleY respectively.

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

C#
VB.NET

void ScaleImage(string imageFile, string imageFileOut)
{
    // Open image file
    CiServer ci = Inlite.ClearImageNet.Server.GetThreadServer();
    CiTools Tools = ci.CreateTools();
    Tools.Image.Open(imageFile, 1);
    Tools.ScaleImage(0.5, 0.5);
    // Save results
    Tools.Image.SaveAs(imageFileOut, EFileFormat.ciEXT);
}

Sub ScaleImage(imageFile As String, imageFileOut As String)
    ' Open image file
    Dim ci As CiServer = Inlite.ClearImageNet.Server.GetThreadServer()
    Dim Tools As CiTools = ci.CreateTools()
    Tools.Image.Open(imageFile, 1)
    Tools.ScaleImage(0.5, 0.5)
    ' Save results
    Tools.Image.SaveAs(imageFileOut, EFileFormat.ciEXT)
End Sub
