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


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

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



The font size in pixels


Angle in degrees in which text will be measured


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


The string to be measured

Return values

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.
