Convert PDF to JPG

[nemonoman]

Anyone seen a script or class to convert an uploaded PDF file into a JPG, GIF or PNG?

This is a little script I wrote to take automatic screenshots of some of our sites. We keep a table (customers) with all of our customers and thier domains. This reads through that table, and passes each url to HTMLDOC (www.easysw.com/htmldoc). HTMLDOC stores a PDF version of a webpage. Then it uses GhostScript to convert the pdf file to a jpg.

The last part is what you are interested in.

passthru("gs -sDEVICE=jpeg -sOutputFile=./shots/$a_row[name]1.jpg -r300x300 ./pdf/$a_row[name].pdf");

Here is the whole script.

                $link = mysql_connect ($server, $user, $password);
                if (! $link)
                        {
                        die ("Couldn't connect to mySQL server");
                        }
                if (!mysql_select_db ($db, $link) )
                        {
                        die ("Coldn't open $db: ".mysql_error() );
                        }
	$getcust = mysql_query("SELECT * FROM customers");
	while($a_row = mysql_fetch_array($getcust))
		{

		echo "$a_row[name]\r\n";

		$a_row[name] =  str_replace(" ", "_", $a_row[name]);

		passthru("htmldoc --webpage -f /vhosts/webpieces.net/httpdocs/screenshots/pdf/$a_row[name].pdf [url]http://[/url]$a_row[location]");
		passthru("gs -sDEVICE=jpeg -sOutputFile=./shots/$a_row[name]1.jpg -r300x300 ./pdf/$a_row[name].pdf");
		$image = "./shots/$a_row[name]1.jpg";

		$thumbImgResized = Imagecreatetruecolor(640, 480); 	

		imagecopyresampled($thumbImgResized, ImageCreateFromJPEG($image), 0 , 0 , 0, 0, (640), (800), 2479, 3300); 

		ImageJPEG($thumbImgResized, "./shots/$a_row[name].jpg");             
		ImageDestroy($thumbImgResized); 

		passthru("rm -rf $image");
	}

Hope this helps!

Thanks for your helpful response. Any advice about using ghostscript? It's a mystery to me.

I honestly don't know much about GhostScript myself. It was installed on my server, and I needed to convert PDF to JPG. I did a quick search on Google and saw that GhostScript could do it!

Here is a link to the GhostScript Page. http://www.ghostscript.com/

Hope this helps some.
