搞了两天，没弄成，宣布失败，求高手帮忙！！
下面这个代码，是可以直接把图片处理为四个角都为园的。
但是现在产生的图片是没生成文件的，想改为处理的文件可以生成一个在指定目录。。
弄了两天，总是不行。。。求高手帮忙看看。。谢谢！
例如运行网址：http://www.xxx.com/pic.php?gopic=1234.jpg
pic.php代码如下：
<br>
<?php <br />
class RoundedCorner { <br>
private $_r; <br>
private $_g; <br>
private $_b; <br>
private $_image_path; <br>
private $_radius; <br>
<br>
function __construct($image_path, $radius, $r = 255, $g = 255, $b = 255) { <br>
$this->_image_path = $image_path; <br>
$this->_radius = $radius; <br>
$this->_r = (int)$r; <br>
$this->_g = (int)$g; <br>
$this->_b = (int)$b; <br>
} <br>
<br>
private function _get_lt_rounder_corner() { <br>
$radius = $this->_radius; <br>
$img = imagecreatetruecolor($radius, $radius); <br>
$bgcolor = imagecolorallocate($img, $this->_r, $this->_g, $this->_b); <br>
$fgcolor = imagecolorallocate($img, 0, 0, 0); <br>
imagefill($img, 0, 0, $bgcolor); <br>
imagefilledarc($img, $radius, $radius, $radius*2, $radius*2, 180, 270, $fgcolor, IMG_ARC_PIE); <br>
imagecolortransparent($img, $fgcolor); <br>
return $img; <br>
} <br>
<br>
private function _load_source_image() { <br>
$ext = substr($this->_image_path, strrpos($this->_image_path, '.')); <br>
if (empty($ext)) { <br>
return false; <div class="clear">
</div>
