# imagettfbbox

(PHP 4, PHP 5)

imagettfbbox — Give the bounding box of a text using TrueType fonts

### Opis

array imagettfbbox ( float `$size` , float `$angle` , string `$fontfile` , string `$text` )

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

### Parametry

`size`

  The font size in pixels

`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

### Zwracane wartości

imagettfbbox() 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.
