PHP GD图像损坏在imagecopy（）
我在使用PHP 5.3.3时遇到了一些奇怪的问题，我正在尝试为图像添加水印。
$body = @imagecreatefromstring($image_data['body']);
imagejpeg($body, null, 85);
$body = @imagecreatefromstring($image_data['body']);
$logo = @imagecreatefrompng(APP_ROOT . self::WATERMARK_PATH);
$body_width = (int) @imagesx($body);
$body_height = (int) @imagesy($body);
$logo_width = (int) @imagesx($logo);
$logo_height = (int) @imagesy($logo);
$image = imagecreatetruecolor($body_width + 4, $body_height + $logo_height);
imagecopy(
$image, $logo,
intval($body_width / 2) - ceil($logo_width / 2), $body_height,
0, 0, $logo_width, $logo_height
);
imagejpeg($image, null, 85);
$body = @imagecreatefromstring($image_data['body']);
$logo = @imagecreatefrompng(APP_ROOT . self::WATERMARK_PATH);
$body_width = (int) @imagesx($body);
$body_height = (int) @imagesy($body);
$logo_width = (int) @imagesx($logo);
$logo_height = (int) @imagesy($logo);
$image = imagecreatetruecolor($body_width + 4, $body_height + $logo_height);
imagecopy(
$image, $body,
1, 1,
0, 0, $body_width, $body_height
);
imagecopy(
$image, $logo,
intval($body_width / 2) - ceil($logo_width / 2), $body_height,
0, 0, $logo_width, $logo_height
);
imagejpeg($image, null, 85);

<?php $body = imagecreatefromjpeg('http://i.stack.imgur.com/KJjDi.jpg'); $logo = imagecreatefromjpeg('http://b.vimeocdn.com/ps/161/161028_300.jpg'); $body_width = (int) imagesx($body); $body_height = (int) imagesy($body); $logo_width = (int) imagesx($logo); $logo_height = (int) imagesy($logo); $image = imagecreatetruecolor($body_width + 4, $body_height + $logo_height); imagecopy( $image, $body, 1, 1, 0, 0, $body_width, $body_height ); imagecopy( $image, $logo, intval($body_width / 2) - ceil($logo_width / 2), $body_height, 0, 0, $logo_width, $logo_height ); header('Content-Type: image/jpeg'); imagejpeg($image, null, 85); ?>
