    in .net Core 6 I’ve create an App to parse text content from a given PDF.

    Everything’s fine but the PREVIEW and the export test shows something is missing…

    I’ve attached the ORIGINAL PDf (named “ACETOLURO (BIM 002).pdf”) and the “copy” same, exported via code using

    [code]Dim ex As New PdfFilter
        ex.FileName = "D:\Prova.pdf"

    named “Prova.pdf

    As u can see, the bottom of the first page is BLANK, here and in some other pages (whole page almost blank)…

    Any suggestion?
