Bug description: lines drawn with imageline() are ugly
Description:
------------
i dont think this is a bug, it may be, and i dont know if reporting this
here will do any good,
when drawing lines in gd, other than 90degree angles; the endings of the
lines always become horisontal
and it looks really, REALLY cheap! it doesnt show when the lines are 1
pixel wide but when drawing thicker lines, it becomes VERY obvious, this
is my greatest obstacle in my project right now, ive emailed boutell.com
but got no answer.
thanks,
Osman Darcan
Reproduce code:
---------------
<?
$im = imagecreate(400, 400) or die ("Cannot Initialize new GD image
stream");
header ("Content-type: image/png");
$grey = imagecolorallocate ($im, 155, 155, 155);
$blue = imagecolorallocate ($im, 0, 0, 255);
$green = imagecolorallocate ($im, 0, 155, 0);
imagesetthickness($im,9);
imageline($im,5,5,50,50,$blue);
imageline($im,50,50,100,300,$blue);
imageline($im,100,300,300,40,$blue);
imageline($im,5+20,5+20,50+20,50+20,$green);
imageline($im,50+20,50+20,60+20,300+20,$green);
imageline($im,100+20,300+20,300+20,40+20,$green);
imagepng($im,"",60);
?>
Expected result:
----------------
try different values for imagesetthickness
Actual result:
--------------
you'll see that some lines look very weird.. im not sure its a bug but
it's sure ugly allright..
php and gd deserves something as simple as a decent option to set
thickness to lines.. shouldnt be so hard to implement?
