pdf with preview image

Hi,

we are also very interested in a feature like this. We have many clients uploading PDFs of brochures and manuals, and it would be great to be able to present a thumbnail/preview from these uploads.

Did some googling and it seems like ImageMagick/Ghostscript can do this, I'm unsure if GD is capable.

Maybe Interactivetools can extend CMSB or create a plugin to do this?

Hi,

I use this script for my projects :

With a little chance, it can function on your server.

Djulia

An example :

if($upload['extension'] == 'pdf') {
    $path_parts = pathinfo($upload['filePath']);
    /*
    [dirname] => /home/www/folder/...
    [basename] => filename.pdf
    [extension] => pdf
    [filename] => filename
    */
   
    $pdf = $upload['filePath'];
    $quality = 90;
    $res = '30x30';
    $exportPath = $path_parts['dirname'].'/'.$record['num'].'_'.$path_parts['filename'].'.jpg';
    exec("'gs' '-dFirstPage=1' '-dLastPage=1' '-dNOPAUSE' '-sDEVICE=jpeg' '-dUseCIEColor' '-dTextAlphaBits=4' '-dGraphicsAlphaBits=4' '-o$exportPath' '-r$res' '-dJPEGQ=$quality' '$pdf'",$output);
}

echo '<img>...';


You must certainly adapt it to your need.

It is also possible to adapt it in a plugin for a use in backend.

I think this would work great for an upload field. We can than run your code to produce and present the thumbnails (maybe there should be some kind of cache). But I was more thinking about a wysiwyg field, then the client must know the url to manually insert the thumbnail and then link it to the PDF. For most clients this would be too technical and difficult.

But thanks for your code, it is an interesting starting point, but I hope Dave and his team will implement this into CMSB.

> (maybe there should be some kind of cache).
Yes, I make some check if the image is generated (for a period of time).
In this case, I use this image.
In the contrary case, I use script.

Thanks!

All the idea's look great!!

i'm going to look into it next week hope to come with some great idea's my self and with my programmers.

I too wish it would be a standard feature in cmsb

Thnx

Hi Maurice

At this time we don't have plans for PDF thumbnails officially but I also like the ideas brought up in this thread. Keep us up to date with how you make out!
