php怎么生成圆角图片(一)

具体如下：

代码如下:

$image_file = $_GET["src"];

$corner_radius = isset($_GET["radius"]) ? $_GET["radius"] : 20; // The default corner radius is set to 20px

$topleft = (isset($_GET["topleft"]) and $_GET["topleft"] == "no") ? false : true; // Top-left rounded corner is shown by default

$bottomleft = (isset($_GET["bottomleft"]) and $_GET["bottomleft"] == "no") ? false : true; // Bottom-left rounded corner is shown by default

$bottomright = (isset($_GET["bottomright"]) and $_GET["bottomright"] == "no") ? false : true; // Bottom-right rounded corner is shown by default

$topright = (isset($_GET["topright"]) and $_GET["topright"] == "no") ? false : true; // Top-right rounded corner is shown by default

$imagetype=strtolower($_GET["imagetype"]);

$backcolor=$_GET["backcolor"];

$endsize=$corner_radius;

$startsize=$endsize*3-1;

$arcsize=$startsize*2+1;

if (($imagetype=="jpeg") or ($imagetype=="jpg")) {

$image = imagecreatefromjpeg($image_file);

} else {

if (($imagetype=="GIF") or ($imagetype=="gif")) {

$image = imagecreatefromgif($image_file);

} else {

$image = imagecreatefrompng($image_file);

}

}
