XorImage Method

Description

Logical XOR the image with another image

Syntax

Visual Basic
Public Sub XorImage( _ ByVal ImgSrc As CiImage, _ Optional ByVal left As Long = 0, _ Optional ByVal top As Long = 0 _ )

Visual Basic

Public Sub XorImage( _
   ByVal ImgSrc As CiImage, _
   Optional ByVal left As Long = 0, _
   Optional ByVal top As Long = 0 _
)

Parameters

ImgSrc: Source image
left: Target position on object.Image. The default value is 0
top: Target position on object.Image. The default value is 0

Remarks

This method sets object.Image pixels to a result of the logical operation between themselves and corresponding pixels of ImgSrc located at left and top offsets.

BitsPerPixel property of object.Image and ImgSrc should be the same.

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

Example

VB Example (VB6)

Sub LogicalMethods(imageFile1 As String, imageFile2 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 imageFile1
  Dim Image As CiImage: Set Image = Ci.CreateImage
  Image.Open imageFile2
    ' Do processing
  Dim x, y: x = 20: y = 20
  Tools.AndImage Image, x, y
  x = x + Tools.Image.Width / 5 + 20
  y = y + Tools.Image.Height / 5 + 20
  Tools.OrImage Image, x, y
  
  x = x + Tools.Image.Width / 5 + 20
  y = y + Tools.Image.Height / 5 + 20
  Tools.XorImage Image, x, y
  
  x = x + Tools.Image.Width / 5 + 20
  y = y + Tools.Image.Height / 5 + 20
  Tools.PasteImage Image, x, y
    ' Save results
  Tools.Image.SaveAs imageFileOut, ciEXT
