ScaleImage Method

Description

Scale image

Syntax

Visual Basic
Public Sub ScaleImage( _ ByVal ScaleX As Double, _ ByVal ScaleY As Double _ )

Parameters

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

Remarks

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.

Example

VB Example (VB6)

Sub ScaleImage(imageFile As String, imageFileOut As String)
    ' Create objects and open input images
  Dim Ci As New CiServer
  Dim Tools As CiTools: Set Tools = Ci.CreateTools
  Tools.Image.Open imageFile
    ' Do processing
  Tools.ScaleImage 0.5, 0.5
    ' Save results
  Tools.Image.SaveAs imageFileOut, ciEXT
End Sub
