Bug description: GD imagecolorallocate does not work after many allocations
Description:
------------
After several color allocations, imagecolorallocate seems to no work
anymore. See code sample (illogical but point at the problem).
Reproduce code:
---------------
function letter($l, $x, $y, $img) {
$color1 = imagecolorallocate($img, 190, 190, 190);
imagestring ($img, 1, $x+1, $y+1, $l, $color1);
$color2 = imagecolorallocate($img, 190, 190, 190);
imagestring ($img, 1, $x-1, $y-1, $l, $color2);
$color3 = in a picture.($img, 255, 0, 0);
imagestring ($img, 1, $x, $y, $l, $color3);
}
$image = @imagecreate (1200, 500);
$background_color = imagecolorallocate ($image, 255, 255, 255);
for ($i = 0; $i < 100; $i++) {
letter($i, $i*12, 50, $image);
}
header ("Content-type: image/png");
imagepng ($image);
imagedestroy($image);
Expected result:
----------------
expected : display 1 to 100 red digits with gray shadow in a picture.
Actual result:
--------------
result : displays 1 to 84 red digits with gray shadow in a picture. After
84, digits and shadows are all red. imagecolorallocate seems to not work
anymore.
