这是一个非常简单的格式转换代码，可以把.PDF文件转换为.JPG文件，代码要起作用，服务器必须要安装Image Magick 扩展。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 $pdf_file = './pdf/demo.pdf'; $save_to = './jpg/demo.jpg'; //make sure that apache has permissions to write in this folder! //(common problem)   //execute ImageMagick command 'convert' and convert PDF //to JPG with applied settings exec('convert "'.$pdf_file.'" -colorspace RGB -resize 800 "'.$save_to.'"', $output, $return_var);   if($return_var == 0) { //if exec successfuly converted pdf to jpg print "Conversion OK"; } else print "Conversion failed.".$output;
