The problem is that A4 is *NOT* exactly 210mm*297mm.

(Further more, the 2.835016835017 is incorrect. You convert from mm to pps by dividing by 25.4 and multiplying by 72. Hence the ratio is 2.83464566929133858267).

The code that I posted in may produces correct sizes.

(Except for the "m65" format, sorry. "m65" is the same as "dl", and should return the same values).

Try this...



<?



function mm2pt($val){

    return floatval($val * 2.835016835017);

    }



$xpdf = pdf_new();

pdf_open_file($xpdf);

pdf_begin_page($xpdf, mm2pt(210), mm2pt(297));



// ...



?>

The DIN paper sizes below are rounded.

Theese functions returns exact paper sizes:



<?php

function paperheight($papername) {

  $name=strtolower($papername);

  switch($name) {

  case "dl": return 11/2.54*72;

  case "m65": return paperheight("c6");

  case "ledger": case "tabloid": return  17*72;

  case "legal": return paperwidth("ledger");

  case "letter": return 11*72;

  default: return paperwidth($name)*sqrt(2);

  }

}

function paperwidth($papername) {

  $name=strtolower($papername);

  switch($name) {

  case "dl": return 22/2.54*72;

  case "m65": return paperwidth("c5");

  case "ledger": case "tabloid": return  14*72;

  case "legal": case "letter": return paperheight("ledger")>>1;

  default:

    $i=strpos("ebca",$name{0});

    $j=substr($name,1);

    if($i!=false && ($j>0 || $j==="0"))

      return 100/(pow(2,($i+$j*4-1)/8))/2.54*72;

    else

      die("Unkown paper format: $papername");

  }

}



$paper = "A4";

$w = paperwidth($paper);

$h = paperheight($paper);

echo "$paper: $w ppt * $h ppt";

?>

I spent a lot of hours tweaking numbers in my PDF source, trying to nudge things the right way, and, invariably, really messing up big-time...



Then one day I realized that all these numbers were supposed to be (INCHES * 72).



Now my PDF code looks more like:

<?php

.

.

.

  pdf_begin_page($pdf, 8.5 * 72, 11 * 72);

.

.  /* set up $helvetica as font */

.

  pdf_set_font($pdf, $helvetica, 9);

  $leading = pdf_get_value($pdf, 'leading');

  pdf_show_boxed($pdf, 0.5 * 72, 0.5 * 72, 4.0 * 72, $leading, 'left', '');

?>



0.0, 0.0 is at the bottom left.

8.5 * 72, 11 * 72 is at the top right.

Everything in between is in x.xx * 72 where x.xx is INCHES.



Suddenly, I can visualize the PDF while I'm typing.



Might work for you too.

Points for CD covers (approximate values)



Front cover           (119x119mm)   => 337.33x337.33 points

Inlay including sides (150x117mm)   => 425.21x331.66 points

Inlay excluding sides (137.4x117mm) => 389.49x331.66 points

When you use the mentioned size of an a4 pdf file it will make a pdf file in the this size: 209.9 x 297 mm. If you want to create a real a4 sized pdf you can use the following:



PDF_begin_page($pdf, 595.3, 842); 



It�s a small step i know... but it�s just the last mm.
