Correcting a couple of the comments above:
1. The array values _are_ documented correctly (LL, LR, UR, UL).
2. The values are relative to the baseline point (lower left) passed in ImageTTFText. I passed the
string "xyzzyXYZZY" at 11 points an 0 angle and got back:
(-1,-12) (84,-12)
(-1,3) (84,3)
Which means the text will start one pixel to the left of the base line point, will rise above the
base line point by 12 pixels and will drop below the baseline point by 3 pixels. (remember that Y
is 0 at the "top" of the image and some large positive integer at the "bottom"
of the image)
3. A non-zero angle _does_ return the proper values. For an angle of 45, with the same example
above, I got:
(-10,-8) (51,-69)
(1,3) (62,-58)
As you can see, the thing is angling upward by about 45 degrees; certainly looks like it rotated
about the base line point.
