Description:
------------
I am filling the background of an image with a transparent red
(it shouldn't have an effect on the rest of the drawing). Over
it, I'm drawing a black, semi-transparent, square.
Reproduce code:
---------------
$img = imagecreatetruecolor(100, 100);
imagealphablending($img, true);
$trans = imagecolorresolvealpha($img,255,0,0, 127);
imagefill($img, 0,0, $trans);
$pTrans = imagecolorresolvealpha($img, 0,0,0, 64);
imagefilledrectangle($img, 10, 10, 50, 50, $pTrans);
imagealphablending($img, false);
imagesavealpha($img,true);
header('Content-Type: image/png');
imagepng($img);
Expected result:
----------------
I would expect the resulting image to be 100% transparent,
except for a grey, 50% transparent square.
Actual result:
--------------
Instead, the black is mixed with the red to form a dark-red
semi-transparent square. The red color should not be there,
because it was 100% transparent.
