I have no used the ColdFusion stuff that you are using, but the call to
GetMapImage does have a DPI parameter, that you can use.<br>
I have no trouble getting the images as I want, although the PDF format
usually reduces quality a bit.<br>
<br>
Try looking at the code in the viewer for "Printable Page", as it shows
how to use the calls.<br>

<p class="MsoNormal">The Streamed Image from the rendering service is
being
poured into a PDF file…the problem is that the quality of the PDF
varies based
on the Resolution my Screen is at when I render the Stream, instead of
being
consistent in the PDF. If I’m at 1024 x 768 the PDF map is grainier
than if I’m
at 1920x1200 resolution when I stream the image How can I address this
to
make the PDF quality the same for all users?<o:p></o:p></p>
