複製程式碼
程式碼如下:
Header ("Content-type: image/png"); $im = imagecreate(400,300); $black = ImageColorAllocate($im, 0,0,0); = ImageColorAllocate($im, 0,0,0); = ImageColorAllocate($im, 0,0,0); im, 184,44,6);
include("gb2utf8.php");
$obj=new gb2utf8();
$obj->gb="123abc中國456
$obj->Convert();
ImageTTFText($im, 20, 0, 5, 50, $white, "SIMKAI.TTF", $obj->utf8); "SIMKAI.TTF", $obj->utf8); ;
ImageDestroy($im);
?>
說明:
需要正確設定font文件,請先確認可以使用font直接(不使用gb2utf8)輸出英文。
