) : array$text
, resource $font
, int $size
, int $space
, int $tightness
, float $angle
) : arrayGives the bounding box of a text rectangle using PostScript Type1 fonts.
The bounding box is calculated using information available from character metrics, and unfortunately tends to differ slightly from the results achieved by actually rasterizing the text. If the angle is 0 degrees, you can expect the text to need 1 pixel more to every direction.

Examples
Example #1 imagepsbbox() usage
<?php
// Create image handle
$im = imagecreatetruecolor(200, 200);
// Allocate colors
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
// Load the PostScript Font
$font = imagepsloadfont('font.pfm');
// Make a bounding box for the font
$bbox = imagepsbbox('Sample text is simple', $font, 12);
// Define our X and Y cordinates
$x = ($bbox[2] / 2) - 10;
$y = ($bbox[3] / 2) - 10;
// Write the font to the image
imagepstext($im, 'Sample text is simple', $font, 12, $black, $white, $x, $y);
// Output and free memory
