GD2绘制图形在浏览器中不能显示
绘制了一个图形,如果是以ANSI格式编码可以在浏览器输出
但是以UTF-8格式编码就不能显示图形,这是什么原因?求指教!!!
代码如下:
<br />
<?php<br />
$im = imagecreatetruecolor(50,25);<br />
<br />
$red = imagecolorallocate($im,255,0,0);<br />
$str = 'ABCDEFGHIJKMNPQRSTUVWXTZabcdefghijkmnpqrstuvwxtz23456789';<br />
$str = substr(str_shuffle($str),0,4);<br />
imagestring($im,5,8,5,$str,$red);<br />
<br />
header('content-type:image/png');<br />
imagepng($im);<br />
imagedestroy($im);<br />
<br />
<br />
