imagettfbbox

(PHP 3>= 3.0.1, PHP 4 )

imagettfbbox -- Give the bounding box of a text using TrueType 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:

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