GIF support for PdfCatalogs (I'm almost there!)

[hknight]

The contrabution PdfCatalogs creates a PDF format catalog. It only supports JPEG and PNG type images. I need support for GIF images so I had an idea: why not convert the GIFs to PNGs in realtime while creatating the PDF document?

 

So I used NETPBM and the short script below to convert GIFs to PNGs

 

<?php 
$netpbmPath = "/home/me/public_html/gallery/netpbm"; // don't put at end 
header ("Content-Type: image/png"); 
$file = ereg_replace('.converted.png','',$_SERVER['QUERY_STRING']); 
echo `$netpbmPath/giftopnm $file | $netpbmPath/pnmtopng`; 
?>

 

I have tested this and the conversion works great!

 

NOW all that needs to be done is to somehow use the converted image instead of GIFs in pdf_catalogue.php.

 

I got the first part down but now I need help on the second part. How can I use the converted image instead of the GIFs in the PDF generation script?

 

Thanks!
