Thanks for the link. I tried out the features, and could only manage to get the "LandScape" one working. When I tried "AutoSize", "Stretch" and "FitWidth", none of it seemed to change what the PDF looked like.
For example, when I was testing Autosize, I had
<body>
<div style="width:1275px; height:2100px;">
Content
</div>
</body>
The width and height correspond to 8.5x14 at 150dpi. When I created the PDF though, it just cut off the content widthwise, and heightwise is still letter size, and the content got cut off and spread across two pages instead of fitting on one legal page.
Am I setting the width and height on the wrong elements? Do I have the set the dpi somewhere?
