The simple code below should write a PDF file on disk. This file should contain an image and two lines of text – next to the image (ignore the use of tables for layout 😛 ):

<cfsetting enablecfoutputonly="yes" showdebugoutput="no">

<cfoutput>
<cfdocument filename="output#Left(server.ColdFusion.ProductVersion,1)#.pdf" 
		format="pdf" overwrite="yes">
	<cfdocumentsection marginleft="1">
        <table>
            <tr>
                <td><img src='../images/image.gif'></td>
                <td>This is a simple text<br>spanning on two lines.</td>
            </tr>
        </table>
    </cfdocumentsection>
</cfdocument>
</cfoutput>

The result is quite different in ColdFusion 7 vs ColdFusion 8, as the following image shows:

In CF8, the PDF text and image appear visible smaller than in CF7.
Now the strange part: if I add unit attribute to cfdocument tag (with any value, ‘cm’ or ‘in’) – the CF8 version shows exactly the same size as CF7.

Anyone has any idea why this happens?
