Bug description: ImageTTFText & ImageTTFBBox don't give accurate rectangle with angle
Description:
------------
Hello,
ImageTTFText & ImageTTFBBox don't give accurate rectangle with angle other
than 0.
I work on a png image.
Reproduce code:
---------------
$xx = 30;$yy = 200;$tsize = 18;$tangle = 45;
$p2 = ImageTTFText ($img, $tsize, $tangle, $xx, $yy,
'blue','C:/Windows/Fonts/arial.ttf',"MAgjpabiT01234567");
$p3 = @ImageTTFBBox($tsize,
$tangle,'C:/Windows/Fonts/arial.ttf',"MAgjpabiT01234567");
for($i=0; $i < 4; ++$i) {
$p3[$i*2] = round($p3[$i*2]+$xx+0.5);
$p3[$i*2+1] = round($p3[$i*2+1]+$yy+0.5);
}
imageline($img,$p2[0],$p2[1],$p2[2],$p2[3],'red');
imageline($img,$p2[2],$p2[3],$p2[4],$p2[5],'red');
imageline($img,$p2[4],$p2[5],$p2[6],$p2[7],'red');
imageline($img,$p2[6],$p2[7],$p2[0],$p2[1],'red');
Expected result:
----------------
I would expext to draw a rectangle fitting exactly around the drawn text.
This is true when angle is 0 but no more when rotating the text. Looks
like the surrounding box shift on the left versus the text when angle
increase.
Actual result:
--------------
I only have png image to show. If needed you can contact me by email.
Thanks for all your efforts in developping PHP.
