# ImageTTFBBox

(3.0.1 - 3.0.18 only, PHP 4 >= 4.0.0)

ImageTTFBBox -- Give the bounding box of a text using TypeType fonts

## Description

``array imagettfbbox` (int size, int angle, string fontfile, string text)`

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

`text`

  The string to be measured.

`size`

  The font size in pixels.

`fontfile`

  The name of the TrueType font file. (Can also be an 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.

`angle`

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

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 horizontallty.

This function requires both the GD library and the FreeType library.
