C# processLegendTemplate

[Tamas Szekeres]

Hi,

You might want to specify parameters for leg_group_html, leg_layer_html and
leg_class_html respectively. Like for example:

[leg_group_html opt_flag=12]
<tr>
    <td colspan=3 bgcolor=#cccccc><b>[leg_group_name]</b></td>
</tr>
[/leg_group_html]

[leg_layer_html order_metadata=legend_order opt_flag=5]
<tr>
    <td>
        <input type=checkbox name="map_[leg_layer_name]_status"
       value=1 [if name=layer_status oper=eq value=2]CHECKED[/if]>
     </td>
    <td colspan=2>
        <a href="[metadata name=href]">[metadata name=layer_title]</a>
    </td>
</tr >
[/leg_layer_html]

[leg_class_html opt_flag=14]
<tr>
    <td width=15> </td>
    <td>
        <img src="[leg_icon width=20 height=10]" width=20 height=10>
    </td>
    <td>
        [leg_class_name]
    </td>
</tr>
[/leg_class_html]

Without adding these parameters

msFreeHashTable(groupArgs);
msFreeHashTable(layerArgs);
msFreeHashTable(classArgs);

will fail in generateLegendTemplate (maptemplate.c)

I suggest to file a bug report on this issue with the requirement of
allowing to specify these template elements without adding parameters.

Best regards,

Tamas
