thanks for answering,
I use the PdfContentByte.showText(BaseFont,size) and I create the font with
BaseFont(file,...), so I need to create the font with
BaseFont(PRIndirectReference (reader of original pdf), num)) and I would
have the font data ?? because currently I search in my system a file with
the same FontName of the PostScriptName of the font from the original
pdf....
