<p>Mit imagettfbbox() kann man die Außenmaße für die Ausgabe
|
||
|
eines Textes im<br>
|
||
|
TrueType-Format ermitteln. Als Parameter wird die Schriftgröße
|
||
|
(size), der<br>
|
||
|
Schriftwinkel (angle), der Name der TTF-Datei als URL oder absoluter Pfad<br>
|
||
|
(fontfile) und der auszugebende Text (text) benötigt. Als Rückgabewert
|
||
|
erhalten<br>
|
||
|
Sie ein Array mit den genauen XY-Koordinaten aller vier Ecken der Schrift.
|
||
|
Im<br>
|
||
|
unteren Beispiel gab der Funktionsaufruf folgende Werte zurück:<br>
|
||
|
1 , -1 , 320 , -1 , 320 , -18 , 1 , -18<br>
|
||
|
Mit diesen Daten könnte man wie im unteren Beispiel gezeigt einen
|
||
|
Kasten um<br>
|
||
|
den Text platzieren.<br>
