Coldfusion: display TIFF blob as a PDF

I must read a blob (a TIFF image) from an Oracle database and display it in a browser as a PDF. I write the blob to a TIFF file, then use <cfdocument> to display the TIFF image as a PDF. The second step is very slow, and on the largest blobs there is not enough memory:

java.lang.OutOfMemoryError: Java heap space.

Converting TIFF to PDF in ImageMagick from ColdFusion is even slower.

Is there a better way to do this in ColdFusion?

Here is my code:

<cfimage action="write" source="#queryName.theTIFFblob#" destination="newfile.tif" >
<cfdocument format="pdf" >
<img src="newfile.tif">
</cfdocument>

Thank you.

galadore and Jones911:

Thanks to you both. I suspected there was a limitation to the tools but hoped to get that confirmed by experts before considering other methods.

Jones911 I upped the CF ram to 1024mb and still hit the wall.

galadore if I find no other solution I may do the conversion offline, using cfschedule perhaps, and email it to the user.

I do not think there is a solution - in the end we are using a different tool than ColdFusion image processing (Java) - but the comments were helpful. Thanks for the input to both of you.
