- srcImage Bitmap
-
The source image.
- findImage Bitmap
-
The image to find inside srcImage image.
- similarity Single
-
The similarity percentage threshold to compare the images.
A value of 100 means find a 100% identical image.
Note: High percentage values with images of big resolutions could take several minutes to accomplish.
TemplateMatch
An Array of
TemplateMatch that contains the
relative top-left corner coordinates of any matched image and their similarity percent.
This is a code example.

' A desktop screenshot, in 1920x1080 px. resolution.
Dim desktopScreenshot As New Bitmap("C:\Desktop.png")

Dim partOfDesktopToFind As New Bitmap("C:\PieceOfDesktop.png")
' Match part of the image in the desktop, with the specified similarity threeshold.
Dim matches As TemplateMatch() = MatchImage(srcImage:=desktopScreenshot,
findImage:=partOfDesktopToFind,
similarity:=80.5F) ' 80,5% similarity threeshold.
For Each match As TemplateMatch In matches

sb.AppendLine()
sb.AppendFormat("Similarity Image Percentage: {0}%", (match.Similarity * 100.0F).ToString("00.00"))
