I download dll and test, but the result has remained the same(
I use this algorithm:
Dim pages() As Integer = {1, 2, 3, 4, 5}
in_stream = New FileStream("in.pdf", FileMode.Open, FileAccess.Read)
out_stream = New FileStream("out.pdf", FileMode.Create, FileAccess.ReadWrite)
fileStamp = New PdfFileStamp(in_stream, out_stream)
st = New Stamp
st.BindImage("black_white_image.gif")
st.Pages = pages
st.Opacity = 0.03F
st.SetOrigin(90, FileHeight / 2 - 36)
st.IsBackground = False
fileStamp.AddStamp(st)
fileStamp.Close()
in_stream.Flush()
in_stream.Close()
out_stream.Flush()
out_stream.Close()
Please can you test new dll with my algorithm and fix it.
