没有那个字体 换一个字体或把字体文件拷到相对应的目录

在C盘路径下 有arial字体文件啊。 
我把putenv('GDFONTFATH=C:\windows\fonts');
改成putenv('GDFONTFATH=C:\Windows\Fonts');
报错为:Warning: imagettfbbox() [function.imagettfbbox]: Could not find/open font in E:\AppServ\www\make_button.php on line 38


但是在文件夹中的确有Arial字体文件

请大侠帮助!~~~

不好意思
报错一直为 Warning: imagettfbbox() [function.imagettfbbox]: Invalid font filename in E:\AppServ\www\make_button.php on line 38

是字体变量的问题。把 
putenv('GDFONTFATH=C:\windows\fonts');
$fontname='Arial';

直接改成
$fontname = 'c:/windows/fonts/arial.ttf'就可以了,大小写不敏感。

我也遇到了这种情况,也按照#4楼的做了,还是出现那种情况,找不到文件名

字体路径的反斜杠是怎么写的,是\还是/,我试了好几种,都不行,并且字体在系统中存在
