B4J Question [Solved] Bitmap comparison

Sub ImageAreSame(bitmap1 As B4XBitmap, bitmap2 As B4XBitmap) As Boolean
    
    Dim bc1 As BitmapCreator
    bc1.Initialize(bitmap1.Width,bitmap1.Height)
    bc1.CopyPixelsFromBitmap(bitmap1)
    
    Dim bc2 As BitmapCreator
    bc2.Initialize(bitmap1.Width,bitmap2.Height)
    bc2.CopyPixelsFromBitmap(bitmap2)

    Dim x, y As Int
    Dim ARGB1, ARGB2 As ARGBColor
    
    For x = 0 To bc1.mWidth-1
        For y = 0 To bc1.mHeight-1

            bc1.GetARGB(x, y, ARGB1)
            bc1.GetARGB(x, y, ARGB2)

            If ARGB1<>ARGB2 Then Return False
        Next
    Next

    Return True
End Sub
