image - iText page number in header within PDF/A -

i have trying adjust code add page number in pdf pdf/a.

i have added font, color scheme , pdf/a creation works if leave out adding addition of pdftemplate.

// pdf created when part removed // though without page number in header pdfpcell cell = new pdfpcell(image.getinstance(total)); cell.setborder(rectangle.bottom); table.addcell(cell);" 

though header page number in too. out of clues how add font pdfpcell. other fields add phrase or paragraph can provide font.

the error thrown is: exception in thread "main" com.itextpdf.text.documentexception: com.itextpdf.text.pdf.pdfaconformanceexception: fonts must embedded. 1 isn't: helvetica @ com.itextpdf.text.pdf.pdfdocument.add(pdfdocument.java:809)

}

please take @ line:

table.addcell(string.format("page %d of", writer.getpagenumber())); 

in line, add string table directly. internally, pdfpcell created, phrase object. no font defined, default font (helvetica, unembedded) used.

please change above line into:

table.addcell(new phrase(string.format("page %d of", writer.getpagenumber()), fontarial); 

this solve 1 problem (unless i've overlooked other instances default font introduced). there other exceptions if want pdf/a level a, though.

i've written example creates pdf/a document based on csv file. i'm adding footer document reusing page event implementation: pdfa1a

the problem experiencing can explained follows: when tell pdfwriter needs create tagged pdf (using writer.settagged();), itext make sure appropriate tags created when adding element objects document. long stick using high-level objects, work.

however, moment introduce objects added @ absolute positions, take responsibility correctly tag content add. in case, adding footer. footers not part of "real content", hence need marked "artifacts".

in example, have adapted page event implementation in way allows me explain 2 different approaches:

in first approach, set role @ level of object:

image total = image.getinstance(t); total.setrole(pdfname.artifact); 

in second approach, mark content artifact @ lowest level:

pdfcontentbyte canvas = writer.getdirectcontent(); canvas.beginmarkedcontentsequence(pdfname.artifact); table.writeselectedrows(0, -1, 36, 30, canvas); canvas.endmarkedcontentsequence(); 

i use second approach pdfptable because if don't, have tag sub-elements of table (every single row) artifact. if didn't, itext introduce tr elements inside artifact (and wrong).
