[Users] legend icons Geoext PDF print

[Rémi Lagoin]

Thanks Andreas,

I also tried this example, the legendPanel works well, printing the PDF is
done, but I only have the layer name in the caption, not the legend image
associated.

Here is my code :

--------------
var mapPanel, printPage;

Ext.onReady(function() {
    // The printProvider that connects us to the print service
    var printProvider = new GeoExt.data.PrintProvider({
        method: "GET", // "POST" recommended for production use
        capabilities: printCapabilities // from the info.json script in the
html
    });
    // Our print page. Tells the PrintProvider about the scale and center of
    // our page.
    printPage = new GeoExt.data.PrintPage({
        printProvider: printProvider,
        customParams: {
            mapTitle: "Printing Demo",
            comment: "This is a simple map printed from GeoExt.",
            copyright: "This is a simple map printed from GeoExt."
        }
    });

    feux = new OpenLayers.Layer.WMS("feux", "http://xxxx/feux",
            {layers: "feux", format: 'image/jpeg', transparent: true},
{singleTile: true});

   // The map we want to print
    mapPanel = new GeoExt.MapPanel({
        region: "center",
        layers: [feux],
        center: [146.56, -41.56],
        zoom: 6
    });

    // The legend to optionally include on the printout
    var legendPanel = new GeoExt.LegendPanel({
        region: "west",
        width: 150,
        bodyStyle: "padding:5px",
        layerStore: mapPanel.layers,
        defaults: {
        style: 'padding:5px',
        baseParams: {
            FORMAT: 'image/png',
            LEGEND_OPTIONS: 'forceLabels:on'
        }
    }

    });

    mapPanel.map.addControl(new OpenLayers.Control.LayerSwitcher());

    var includeLegend; // controlled by the "Include legend?" checkbox

    // The main panel
    new Ext.Panel({
        renderTo: "content",
        layout: "border",
        width: 700,
        height: 420,
        items: [mapPanel, legendPanel],
        bbar: ["->", {
            text: "Print",
            handler: function() {
                // convenient way to fit the print page to the visible map
area
                printPage.fit(mapPanel, true);
                // print the page, optionally including the legend
                printProvider.print(mapPanel, printPage, includeLegend &&
{legend: legendPanel});
            }
        }, {
            xtype: "checkbox",
            boxLabel: "Include legend?",
            handler: function() {includeLegend = this.checked}
        }]
    });
});
-----------
And an extract of my Yaml config :

       - !columns
           widths: [100]
           absoluteX: 300
           spacingAfter: 5
           items:
            - !legends
               maxIconWidth: 0
               maxIconHeight: 0
               classIndentation: 0
               layerSpace: 5
               layerFontSize: 10


Is something wrong ?

Thanks a lot,

Rémi
