Sure, Fabien, here it is. Note that basically, I took your program and
deleted what I didn' t need.
I didn't need, for instance, a file pickup list -- That's because I know
beforehand which file I want to display.

I could put to good use some niceties like a zooming button, but I can do
without them.


























*Private $hPdf As New PdfDocumentPublic Sub Form_Open()  Me.Center  Try
$hPdf.Open("/home/fernando/.config/libreoffice/4/user/basic/EmpregoDoHífen.pdf")
If Error Then      Message.Error("Unable to open the file : " &
"/home/fernando/.config/libreoffice/4/user/basic/EmpregoDoHifen.pdf")
Return    Endif  DocumentView1.Count = $hPdf.Count
DocumentView1.RefreshEndPublic Sub DocumentView1_Layout(Page As Integer)
DocumentView1.Layout.Width = $hPdf[Page + 1].Width + 150
DocumentView1.Layout.Height = $hPdf[Page + 1].Height + 150EndPublic Sub
DocumentView1_Draw(Page As Integer, Width As Integer, Height As Integer)
Paint.DrawImage($hPdf[Page + 1].Image, 0, 0, Paint.Width,
Paint.Height)EndPublic Sub Button2_Click()  Me.CloseEnd*
