Rails：attachment_fu插件，将PDF上传文件转换为图像

Question

Yo,

I've got attachment_fu set up on my server, and it works just fine. My goal, however, is to be able to upload PDFs and have them convert to image (then use all the pre-built attachment_fu options like resize and thumb produce the desired images). What currently happens is that PDFs upload and remain PDFs, whereas images go through all the motions of resizing and whatnot.

How can I get the functionality I want? Is there a simple way to go about doing this using the tools I already have, or should I just manually invoke RMagick to do the initial conversion? If so, how can I do that and then pass off the file to attachment_fu for handling?

Thanks, --Matchu
