How to set fit width when embedding pdf in Chrome?

When I embed a pdf to view on Chrome/ Firefox , no matter I set width /
set the parameter , it does not change the width of the pdf content, the
only thing I can control is the pdf viewer size but not pdf page size, are
there any way to control it? thanks
<object type="application/pdf" data="2010%20AHS%20XC%20Results.pdf"
width="1500" height="1200"></object>
<object type="application/pdf"
data="2010%20AHS%20XC%20Results.pdf#view=fit" width="1500"
height="1200"></object>
<object type="application/pdf" data="2010%20AHS%20XC%20Results.pdf"
width="1500" height="1200">
<parm name="view" value="fit/>
</object>
