Digg  imagesetstyle
Set the style for line drawing
(PHP 4 >= 4.0.6, PHP 5)
Example 1022. imagesetstyle() example<?phpThe above example will output something similar to:  Code Examples / Notes » imagesetstylecruz
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. yhoko
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. michael_todd_335
Watch out! If you pass imagesetstyle() an empty array as the second argument, it will crash your server! I was messing with it just earlier and accidentally did so, and the page took a good minute to process, when my Apache server came up with the good ol' Windows 'Send Error Report' window. zackbloom
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; } |
