I use the library and example located here
I want to have an image appear at the center of generated QR code. The size of the image is about 1/4~1/5 of the QR code image size. For example I want to make the following logo image further smaller.
I tried the following code to make the logo's size is 1/5 of QR code image size and it didn't work. Obviously I did something wrong. Highlighted code are modified.
Could someone show what I did incorrectly, please?

For x = 0 To bc.mWidth - 1
For y = 0 To bc.mHeight - 1
bc.GetARGB(x, y, argb)
LogoBC.GetARGB(x/5, y/5, largb) 'this line caused error: java.lang.ArrayIndexOutOfBoundsException: length=37636; index=37639
If largb.a > 0 Then
largb.a = 200
LogoBC.SetARGB(x/5, y/5, largb)
bc.BlendPixel(LogoBC, x/5, y/5, x, y)
End If
Next
Next
Return bc.Bitmap
