Bounding-box coordinates


Returns an eight-element array, consisting of the x and y coordinates of the bounding box (the rectangle enclosing the rendered text) of the specified text. The coordinates are independent of the angle of rotation of the text. Thus, if the image is rotated, the coordinates are taken as the upper-left corner of the box around the text relevant to the text, not the upper-left corner of the rotated string. The elements of the array are arranged as shown in the following table.

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


Existing since version 3.0.1


Example 446. Display coordinates

// display coordinates
$array = imagettfbbox(20, 20, "VERDANA.TTF", "SAMPLE!");
while (list($key, $val) = each($array)) {
    echo "$key => $val<BR>";
