[UMN_MAPSERVER-USERS] C# processLegendTemplate

[Jean Michel PIERRET]

Hi,

 

            Thank you for your assistance, while seeking I found a solution
to circumvent the problem.

 

int ret;

layerObj lo = null;

classObj co = null;

imageObj io = null;

 

lo = this._map.getLayerByName(layer);

 

io = co.createLegendIcon(this._map, lo, 19, 15);

ret = co.drawLegendIcon(this._map, lo, 19, 15, io, 0, 0);

 

Regards.

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

Hi,

 

How I can use processLegendTemplate in c#

 

My source :

 

            map = new mapobj(@"C:\Fichier.map");

 

            ...

 

            string str = null;

            string[] names = null, values = null; 

            

            names = new string[] {"map" };

            values = new string[] { @"C:\Fichier.map" };

 

            str = map.processLegendTemplate(names, values, names.Length);

 

            ...

 

Error :

 

{"msFreeHashItems(): Hash table error. Can't free NULL
table;msFreeHashItems(): Hash table error. Can't free NULL
table;msFreeHashItems(): Hash table error. Can't free NULL table"}

 

 

Thanks for your help.
