<p class=MsoNormal>Hi All, <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span lang=EN-US>First I’m just going to tell you that
I’m not really a programmer, I’m more of a script kiddie, so bare
with me.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>The thing is that we got a customer that wants
to limit how close the user can zoom in to the map. So I started to have a look
and found out that there was something that made the map not zoom in closer
than the scale 1:1. So I started do look in the code for what was preventing
this, but I didn’t find anything in the zoom widgets or in the zoom
functions in Map.js. So I started to think there was something in openlayers
that made it impossible to zoom in more. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Ok, so eventually I found out that we can send
some options when we initialize the open layers map, and I guess that 1:1 is
the default value. <a href="http://trac.openlayers.org/wiki/SettingZoomLevels">http://trac.openlayers.org/wiki/SettingZoomLevels</a><o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>So I looked in the code for where we
initialize an open layer map and found something on line 98 (this is MGE2009 so
the exact lines might have changed). Anyway I thought that I would try to send
some more options to the map and changed line 94 from<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>var options = {controls: [], fallThrough:
true};<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>to<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>var options = {controls: [], fallThrough:
true, minScale: 10000};<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>When I reload my map it initializes on
scale 1:10000, I can zoom in but not out. I try to change minScale to maxScale,
to make the opposite happen. But when I do that, nothing happens in the map, it
works like I had sent no extra option at all.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>So, could someone explain this behavior?
And could someone tell me how to solve my problem without using fixed
zoomscales?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Best regards<o:p></o:p></span></p>
