Description:
------------
When drawing a polygon with the default thickness everything is fine;
but when setting the thickness of the line > 1, I get strange results.
It looks as if certain lines of the polygons are not being drawn with
the correct thickness.
Reproduce code:
---------------
function getPolygon($width, $border_width, $sides)
{
$xcen = $width; $ycen = $width; $incr = 360/$sides;
$angle = 180; $k = 0; $max_height = 0;
for($j = 0; $j < $sides; $j++)
{
$points[$k] = $xcen + $width * sin(deg2rad($angle)) +
$border_width;
$k++;
$points[$k] = $ycen + $width * cos(deg2rad($angle)) +
$border_width;
$max_height = max($max_height, $points[$k]);
$k++;
$angle += $incr;
}
$img = imagecreatetruecolor(2*$width+10,
$max_height+$border_width+10);
$bg = imagecolorallocate($img,255,255,255);
ImageFill($img, 0, 0, $bg);
imagecolorallocate($img, 255, 255, 255);
$black = imagecolorallocate($img,0,0,0);
imagesetthickness($img,$border_width);
imagepolygon($img,$points,$sides,$black);
header("Content-type: image/gif"); imagegif ($img);
imagedestroy($img);
}
getPolygon(100, 5, 9);
Expected result:
----------------
For 9 sides, it should be like http://www.gabber.nl/cp/geometry_1px.gif
with a thicker line.
Actual result:
--------------
The output is http://www.gabber.nl/cp/geometry_5px.gif . This
happens
for most values of sides.
