復制代碼 代碼如下:

function pdf2png($pdf, $filename, $page=0) {
if (!extension_loaded('imagick')) {
exit('no imagick');
return false;
}
if (!file_exists($pdf)) {
return false;
}
$im = new Imagick();
$im->setResolution(120, 120);
$im->setCompressionQuality(100);
$im->readImage($pdf . "[" . $page . "]");
$im->setImageFormat('png');
$im->writeImage($filename);
$im->readImage($filename);
$im->resizeImage(120, 150, Imagick::FILTER_LANCZOS, 1);
$im->writeImage($filename);
return $filename;
}
