)Gives 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.
textThe text to be written.
font_indexA font resource, returned by imagepsloadfont().
size
size is expressed in pixels.
spaceAllows you to change the default value of a space in a font. This amount is added to the normal value and can also be negative. Expressed in character space units, where 1 unit is 1/1000th of an em-square.
tightness
tightness allows you to control the amount
of white space between characters. This amount is added to the
normal character width and can also be negative.
Expressed in character space units, where 1 unit is 1/1000th of an
em-square.
angle
angle is in degrees.
Returns an array containing the following elements:
| 0 | left x-coordinate |
| 1 | upper y-coordinate |
| 2 | right x-coordinate |
| 3 | lower y-coordinate |
| Version | Description |
|---|---|
| 7.0.0 | T1Lib support was removed from PHP, thus this function was removed. |
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, $y);
// Output and free memory
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>
