Centered text in a PDF file 1

[gullipe]

Hi

I am new to this Acrobat (PDF) forum (but have been occasionally on the Fortran forum for some years now). I am trying to write a PDF code, but I have problems centering text. Below is a short "program" that writes the text "Centered text" starting at position x=100, y=600. But how do I center this text at the position 100,600 ? Can anyone help?

I've never run into anyone trying to create a PDF by coding it - what most of us do is create a document that looks the way we want it to, in Word, Excel, Publisher, whatever, and then 'Print' to Acrobat Distiller or CutePDF or whatever.

Hi FredWagner

The problem is that the users of the program, that I am modifying do not all have "printers" like Acrobat Distiller, CutePDF or PDFWriter etc.

Anyway I desided to try to make a PDF file myself (with the program), and it has been successful up to now with the help of the PDF Reference manuals from Adobe (can be found on the internet) and the ISO 32000 PDF standard.

But there seems to be no text "centering" possibility in the PDF script (I have not found any yet at least). I thought that someone here might have the solution.

You'd probably have better luck on Adobe's Acrobat SDK list:
