PHP图像处理--最强的类

Mon, 03 Apr 2006 07:06:25 GMT

demo:

require_once "imgfilter.inc.php";

$chain = array();
//$chain[] = array("resize" ,array("width"=>"80", "height"=>"130"));
//$chain[] = array("roundcorner2",array("radius"=>"500px","transparent"=>"100"));
//$chain[] = array( "blend", array("background"=>"#555555"));
//$chain[] = array("cropsquare");
//$chain[] = array("border", array("color"=>"#FF0000"));
//$chain[] = array("grayscale");
$chain[] = array("overlay",array("overlay"=>"add_green_white_195x63.png"));

$m = new ImageModifier($chain);
$m->load(SITE_ROOT."MyTest/imgfilter/Nike_Swoosh_bg.jpg");
echo $m->getTag();

其中$chain数组是参数设定,然后直接调用原图像进行处理,还有缓存功能.效率也非常高.
