HTML Legend with Status Checking...<BR><BR></FONT></DIV>Gladly. Here is
my legend code:<BR><BR>[leg_group_html]<BR>
<tr><BR> <td colspan=3
bgcolor=#cccccc><b>[leg_group_name]</b></td><BR>
</tr><BR>[/leg_group_html]<BR><BR>[leg_layer_html]<BR>[/leg_layer_html]<BR><BR>[leg_class_html]<BR>
<tr><BR> <td
width=15> </td><BR>
<td><BR> <img
src="[leg_icon width=15 height=15]" width=15
height=15><BR>
</td><BR>
<td><BR>
[leg_class_name]<BR>
</td><BR> </tr><BR>[/leg_class_html]<BR><BR><BR>However, it
does not work as you say (and as the documentation on the web page says!).
Layers that are "off" do not show up (that's as expected and what I
want), that's fine, but layers that are out of SCALE DO show up, and that's
not as expected and that's not as the documentation states and that's NOT what
I want. For example, I have a layer called Ethiopia_Rivers...here's what
it looks like:<BR><BR>LAYER<BR> NAME "Ethiopia_Rivers"<BR> TYPE
LINE<BR> STATUS off<BR> GROUP Ethiopia<BR> DATA
"ethiopia_rivers"<BR> HEADER
'ethiopia_rivers.shp_header.html'<BR>
CLASS<BR> MAXSCALE
8710165<BR> Name 'Ethiopia
Rivers'<BR> COLOR 102 204
255<BR> TEMPLATE
ethiopia_rivers.shp_query.html<BR> END #
CLASS<BR>END # LAYER<BR><BR>Now, when I'm viewing my map at full extent,
my scale factor is 1:<FONT size=3><B> 20136789</B></FONT>, therefore if I
click on the Ethiopia_Rivers layer at that zoom level, nothing shows up in the
map. This is the exact behavior that I would expect...I'm out of scale
for that layer, so it doesn't show up in the map until I zoom in. The
PROBLEM, however, is that the "Ethiopia Rivers" icon and label pop up in my
legend...this is counter-intuitive, contrary to the documented behavior of
Mapserver, and just flat-out frustrating! If the layer is not showing up
in my map (because it's out of scale), then it should NOT be in my legend
either. Grrrr!!! Pardon me for sounding bitter...I'm not lashing
out at you, I'm very grateful for your help, I'm just frustrated at
Mapserver.<BR><BR>Thanks!<BR><BR>Martin, Daniel wrote:<BR>

I <BR>have sub-classed many of my layers so that symbols show up in different <BR>sizes depending on how far zoomed in you are. In other words, I'm using <BR>"MINSCALE" and "MAXSCALE" in my classes, but all of my classes show up <BR>in the legend and that's really annoying! I want ONLY the in-scale <BR>symbol to show up in the legend as it does in the map...any tips on how <BR>to do this without Mapscript? I see the "if" conditional statements in <BR>the HTML Legend How-to, but there's no status of "SCALE" to
check with <BR>those statements... if I could put an if statement in my legend template <BR>that checked whether or not a class or layer was in scale, then I'd be <BR>in business...any way to do this?<BR><BR>Thanks!<BR><BR><BR></PRE></BLOCKQUOTE><PRE wrap=""><!----><BR><BR><BR></PRE></BLOCKQUOTE><BR></BLOCKQUOTE></BODY></HTML>
