PHP实现PDF转图片的详细过程(使用imagick)

php --ri imagick

yum install ghostscript

/**
 * 将pdf文件转化为多张png图片
 */
function pdfToPng()
{
    $pdf = 'https://solveset.oss-cn-beijing.aliyuncs.com/1671686912.pdf';
    $path = public_path('uploads/');
    $im = new \Imagick();
    $im->setResolution(120, 120); //设置分辨率 值越大分辨率越高
    $im->setCompressionQuality(100);
    $im->readImage($pdf);
    $return = [];
    foreach ($im as $k => $v) {
        $v->setImageFormat('png');
        $fileName = $path . md5($k . time()) . '.png';
        if ($v->writeImage($fileName) == true) {
            $return[] = $fileName;
        }
    }
    print_r($return);
}
