Error in Merge function

[D-Off]

I find a error in function Merge (GflAx Light Library 2.70). For example, make the project in VB.NET, create a form:

Code: Select all

Public Class Form1
    Dim gf As New GflAx.GflAx

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        gf.LoadBitmap("C:\test1.jpg")
        gf.MergeAddFile("C:\pr.jpg", 50, 10, 10)
        gf.Merge()
        gf.MergeClear()
    End Sub
End Class

The files 100% exist and way correct. Other functions works normally, but gf.Merge except a error (screenshot)

Excuse me, I have wrong understood, what use this function. But now appeared other problem. See the source code and results:

Code: Select all

Dim gf As New GflAx.GflAx

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        gf.NewBitmap(300, 200)
        gf.MergeAddFile("a.jpg", 50, 0, 0)
        gf.MergeAddFile("b.jpg", 50, 0, 0)
        gf.Merge()
        gf.MergeClear()
        PictureBox1.Image = Image.FromHbitmap(gf.GetPicture.Handle)
        gf.SaveFormat = GflAx.AX_SaveFormats.AX_BMP
        gf.SaveBitmap(System.Environment.CurrentDirectory & "\outGFL.bmp")
        PictureBox1.Image.Save(System.Environment.CurrentDirectory & "\outPB.bmp")
    End Sub

Such scene appears here is In PictureBox1:

But GflAx it is correct saves:

Why such different results?
