我正在尝试将我的功能从简单地调整图像大小扩展到添加水印。问题是没有添加水印。我已经确认路径是正确的。为什么它不起作用?
$image = imagecreatefromjpeg($this->getFile());
$size = getimagesize($this->getFile());
$watermark = imagecreatefrompng('../watermark.png');
$watermark_width = imagesx($watermark);
$watermark_height = imagesy($watermark);
$dest_x = $size[0] - $watermark_width - 10;
$dest_y = $size[1] - $watermark_height - 5;
//die($watermark_width);
$thumb_image = imagecreatetruecolor($this->getThumbWidth(), $this->getThumbHeight());
imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);
imagecopyresampled( $thumb_image, $image, 0, 0, 0, 0, $this->getThumbResizeWidth(), $this->getThumbResizeHeight(), $this->getWidth(), $this->getHeight() );
imagejpeg( $thumb_image, $this->getThumbDestination(), $this->getThumbQuality() );
imagedestroy($thumb_image);
imagedestroy($image);
