# imageftbbox

(PHP 4 >= 4.0.7, PHP 5, PHP 7)

imageftbbox — Give the bounding box of a text using fonts via freetype2

### Description

imageftbbox ( float `$size` , float `$angle` , string `$fontfile` , string `$text` [, array `$extrainfo` ] ) : array

This function calculates and returns the bounding box in pixels for a FreeType text.

> Note:

> imageftbbox() is an extended variant of imagettfbbox() which additionally supports the `extrainfo`.

### Parameters

`size`

  The font size in points.

`angle`

  Angle in degrees in which `text` will be measured.

`fontfile`

  The name of the TrueType font file (can be a URL). Depending on which version of the GD library that PHP is using, it may attempt to search for files that do not begin with a leading '/' by appending '.ttf' to the filename and searching along a library-defined font path.

`text`

  The string to be measured.

`extrainfo`

  Possible array indexes for `extrainfo`
  Key | Type | Meaning
  --- | --- | ---
  linespacing | float | Defines drawing linespacing

### Return Values

imageftbbox() returns an array with 8 elements representing four points making the bounding box of the text:

0 | lower left corner, X position
1 | lower left corner, Y position
2 | lower right corner, X position
3 | lower right corner, Y position
4 | upper right corner, X position
5 | upper right corner, Y position
6 | upper left corner, X position
7 | upper left corner, Y position

The points are relative to the text regardless of the `angle`, so "upper left" means in the top left-hand corner seeing the text horizontally.

### Examples

Example #1 imageftbbox() example

`<?php
// Create a 300x150 image
$im = imagecreatetruecolor(300, 150);
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
// Set the background to be white
imagefilledrectangle($im, 0, 0, 299, 299, $white);
// Path to our font file
$font = './arial.ttf';
// First we create our bounding box
$bbox = imageftbbox(10, 0, $font, 'The PHP Documentation Group');
// This is our cordinates for X and Y
$x = $bbox[0] + (imagesx($im) / 2) - ($bbox[4] / 2) - 5;
$y = $bbox[1] + (imagesy($im) / 2) - ($bbox[5] / 2) - 5;
imagefttext($im, 10, 0, $x, $y, $black, $font, 'The PHP Documentation Group');
// Output to browser
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
?>`
