IF we accept the idea that a bouding box is returned then: $bbox= imageftbbox ( $size, $angle, $font, $txt); $width = abs($bbox[4] - $bbox[0]); $height = abs($bbox[1] - $bbox[5]); may be a better kind of math. But it depends... You may want to subtract yet another '1' from both the width and the height. But try drawing a "p" and next try a "d". Their bounding boxes differ 1 px in height. Of course the respective boxes, by imagefttext(), are placed at a different y coordinate. I noticed that if a "p" or a "b" is drawn at (0, 30) the first character of the string actually starts on, fills, the third horizontal pixel. Also: if your image is only 30 pixels in heigth, drawing text at (0, 30) means that the bottoms parts of "p", "q", "y" and alike are somewhere else... ---- Manual Page -- http://www.php.net/manual/en/function.imageftbbox.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60161 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60161&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60161&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60161&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60161&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60161&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60161&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60161&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60161&report=yes Search -- http://master.php.net/manage/user-notes.php
