刚学IMS，对里的参数搞不太懂！

<P>在MapFrame.htm中的</P>
<P>var mWidth = getMapWidth();<BR>  var mHeight = getMapHeight();<BR>  var sWidth = screen.width;<BR>  var sHeight = screen.height;<BR>  var ovRatio = mWidth / mHeight;<BR>  var locHeight = parseInt(mHeight/5);<BR>  var locWidth = parseInt(locHeight*ovRatio);<BR>  var loadBannerLeft = parseInt((mWidth - 273)/2);<BR>  var loadBannerTop = parseInt((mHeight - 30)/2);<BR>  <BR>  vspc2 = mHeight;</P>

<P>ArcIMSparame.js中的</P>
<P>var panFactor = 85/100;<BR>var zoomFactor = 2</P>
<P>var selectMargin = 25/100;</P>
<P>var selectPointMargin = 25/1000<BR></P>
