PDF_get_value

Note:

imagewidth and imageheigh do not return the actual width and height.  Instead they are 2 times the actual width and height.  I don't understand why, but this seems to be the case with multi page tiffs (and maybe other images).  In order to insert a multi page tiff into a PDF without out of control extra space do the following:

<?php
$pdf = pdf_new();
pdf_set_parameter($pdf, "licensefile", "/etc/pdflib/licensekeys.txt");
pdf_open_file($pdf, "/tmp/tifftest.pdf");

for ($i=1; $i<=4; $i++) {

$image = pdf_open_image_file($pdf, "tiff", "/tmp/test.tif", "page", $i);

$w = pdf_get_value($pdf, "imagewidth", $image);
$h = pdf_get_value($pdf, "imageheight", $image);

// $w and $h are at this point 2*width and 2*height!!

// To place the image without having lots of extra space:

pdf_begin_page($pdf, $w/2, $h/2);
pdf_place_image($pdf, $image, 0, 0, 0.5);
pdf_close_image($pdf, $image);
pdf_end_page($pdf);

}
 
pdf_close($pdf);

?>

$width = PDF_get_value($p, "imagewidth", $image);

There should be many more. For example I found this in the manual, wich was very helpfull for me:
$textx = pdf_get_value($p, "textx", 0);
$texty = pdf_get_value($p, "texty", 0);
These will extract the current textposition in the document.

The Magic keywords are:
IMAGEWIDTH, IMAGEHEIGHT, RESX, RESY,
CAPHEIGHT, ASCENDER, DESCENDER, FONT
I looked in the sourcecode ...

See the main PDF manual page (the "PDF" link to the left) for the magic words that this function accepts.

To get the current font size, use something like this:

<?php $fontheight = PDF_get_value($pdf, "fontsize"); ?>
