 Sub ConvertiPdfImg(nomefile As String)
     Dim Render As PDFRenderer
     Dim img As Bitmap
     Render.Initialize("",Main.pthDOC,nomefile)
     For i = 1 To Render.PageCount
        img = Render.renderPageforDisplay(i)
        ' now save img in a file
        Dim out AsOutputStream
        out = File.OpenOutput(File.DirRootExternal, "page" & i & ".png", False)
        b.WriteToStream(out, 100, "PNG")
        out.Close
     Next
End Sub

What different between renderPageforPrint and renderPageforDisplay?
Why converted img file has background black?

Te lo spiego in italiano, uno serve a fare rendering per apparire sullo schermo il secondo solo per essere stampato e ovviamente sono due cose differenti.

P.S. Apri un nuovo argomento per ogni domanda cosi sarà più facile per gli altri trovare le risposte alle stesse tue domande consultando i titoli degli argomenti

one to make rendering to appear on the screen the second only to be printed and of course there are two different things.

P.S. Open new thread

The library was wrapped up by Don Manfred, he can know the problem. If he does not answer you anymore, it seems better to follow his suggestion and open another thread. He'll surely have a better answer from you ;-)

I think that the problem was on the creation of pdf. For now i solved with writing a white rect big such as the page before write any others components
Thank everyone
