imagettfbbox returning 0's

[alias301reader]

when i use $box = imagettfbbox (20, 0, "arial", 55);
then $box[1] & $box[6] are both zero

any help would be very appreciated!

the fourth parameter should be a string. why are you passing an integer? if you intend the string to be 55 then pass the arguments thus:

$box = imagettfbbox(20, 0, "arial", "55");

i suspect that the function is interpreting the integer 55 as a null string. but also i would expect the x value for the left hand corners to be zero in most cases (meaning left aligned). that explains $box[6]. i suspect that $box[1] is zero (if you have not made a mistake and intended to type $box[0]) because there is no text and therefor the box is zero height. but this would also mean that $box[3] should also be zero.
