In Visual Basic and C#, you can call this method as an instance method on any object of type Image. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

If an image is not a Bitmap instance, a temporary Bitmap is created for the check.

Note

This method compares images by raw content. If the images have padding in each stride (content row), padding content is considered as well.
