Пример 1. imagesetstyle() example

$w = imagecolorallocate($im, 255, 255, 255);
$red = imagecolorallocate($im, 255, 0, 0);
/* Draw a dashed line, 5 red pixels, 5 white pixels */
$style = array($red, $red, $red, $red, $red, $w, $w, $w, $w, $w);
imagesetstyle($im, $style);
imageline($im, 0, 0, 100, 100, IMG_COLOR_STYLED);
/* Draw a line of happy faces using imagesetbrush() with imagesetstyle */
$style = array($w, $w, $w, $w, $w, $w, $w, $w, $w, $w, $w, $w, $red);
imagesetstyle($im, $style);
$brush = imagecreatefrompng("http://www.libpng.org/pub/png/images/smile.happy.png");
$w2 = imagecolorallocate($brush, 255, 255, 255);
imagecolortransparent($brush, $w2);
imagesetbrush($im, $brush);
imageline($im, 100, 0, 0, 100, IMG_COLOR_STYLEDBRUSHED);

`When lines drawn with imagesetstyle seem to produce a thin white line only, make sure antialiasing is disabled.
<?
imageantialias($im, false);
$style = array($gridxcolor, $gridxcolor, IMG_COLOR_TRANSPARENT, IMG_COLOR_TRANSPARENT);
imagesetstyle($im, $style);
imageline($im, $x, 0, $x, $ymax+5, IMG_COLOR_STYLED);
imageantialias($im, true);
?>
Setstyle and Antialias don't go together.`

`Use this to set the style to any combination of pixels.
You can pass as many modifiers as you wish.
Use the format [num]r[red]g[green]b[blue].
For example:
$im=dashed($im,"4r255g0b0","2r0g255b0","5r0g0b255");
imageline($im, 0, 0, 600, 600, IMG_COLOR_STYLED);
function dashed($im){
$size = func_num_args();
for($i = 0; $i < $size; $i++){
$arg = func_get_arg($i);
if(!is_resource($arg)){
$r=substr($arg,strpos($arg,"r")+1,
strpos($arg,"g")-strpos($arg,"r")-1);
$g=substr($arg,strpos($arg,"g")+1,
strpos($arg,"b")-strpos($arg,"g")-1);
$b=substr($arg,strpos($arg,"b")+1,
strlen($arg)-strpos($arg,"b"));
$color = imagecolorallocate($im,$r,$g,$b);
$x = substr($arg,0,strpos($arg,"r"));
$vals[$i] = array_fill(0,$x,$color);
}
}
for($k=0;$k<count($vals)+1;$k++)
if(array_key_exists($k,$vals)) $prop=array_merge($prop,$vals[$k]);
imagesetstyle($im, $prop);
return $im;
}`

`When drawing lines that are >1px thick you'll have to setup the array corresponding to this fact (since there's no multi-array support for this function).
For example if the line's 3 pixels thick each 2nd color goes to the 2nd line, each 3rd color to the 3rd line and so on.`
