Use a brush to create a thick line.



To create a 3x3 red brush:



<?php

$brush_size = 3;

$brush = imagecreatetruecolor($brush_size,$brush_size);

$brush_color = imagecolorallocate($brush,255,0,0);

imagefill($brush,0,0,$brush_color);

imagesetbrush($im,$brush);

?>



Then use imageline() or imagepolygon() with IMG_COLOR_BRUSHED as the color.



To stop using the brush, destroy it:



<?php imagedestroy($brush); ?>



The brush can also be created from an existing image.
