ah... the problem between imageftbbox() and imagefttext() lies in the mirroring of the y-axes. Below you see, for a font-size 16 the boudingboxes of "b", "p" and "bp": < b: w=9 h=15 b(0,-1) b(9,-1) b(9,-16) b(0,-16) < p: w=9 h=16 p(0,4) p(9,4) p(9,-12) p(0,-12) < bp: w=20 h=20 bp(0,4) bp(20,4) bp(20,-16) bp(0,-16) If drawing "bp" using imagefttext() at y=0, the the top of "bp" indeed is at y=-16, and the bottom of "bp" at y=4. (Plus or minus a pixel here and there, because at y=0 there actually is a vissible pixel.) ---- Manual Page -- http://www.php.net/manual/en/function.imageftbbox.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60166 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60166&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60166&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60166&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60166&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60166&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60166&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60166&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60166&report=yes Search -- http://master.php.net/manage/user-notes.php
