Návratové hodnoty
imagettfbbox() returns an array with 8 elements representing four points making the bounding box of the text:
| 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 |
The points are relative to the text regardless of the
angle, so "upper left" means in the top left-hand
corner seeing the text horizontally.
