任何处理JPEG的PHP函数似乎都不能在我的服务器上运行.
这段代码:
<?php
$im = imagecreatetruecolor(120, 20);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color);
header('Content-type: image/jpeg');
imagejpeg($im);
imagedestroy($im);
?>
创建一个空文件.
使用GIF或PNG函数将按预期创建包含文本"A Simple Text String"的图像.
这个:
$im = imagecreatefromjpeg("test.jpg");
回报
Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: 'test.jpg' is not a valid JPEG file in /path/to/test.php on line 2
