[Geoserver-users] GIF - transparent

[Holb E. <hol...@ax...>]

Hi!

I would like to animate a wms layer from javascript. I use a image/gif output format. I animate a viewparam - type datetime. It works but the gif is not transparence.
If I add a 'transparent:true' pair to layer params, its wrong.

I use OpenLayers with Geoserver 2.3.1 and Windows7

My script:
it works
                wms_l = new OpenLayers.Layer.WMS("Mérések",
                                wMS_ServiceURL,
                                {
                                      layers: wms_layer
                                    , request:"animate"
                                    , featurePrefix: featureprefix
                                    , viewparams: view_Params
                                    , aparam:"time"
                                    , avalues:"2014-02-01,2014-02-05"
                                    , format:"image/gif";subtype=animated"
                                    , format_options: "gif_frames_display:200;gif_loop_continuosly:true"
                                    , version:"1.1.1"

                                },
                                {
                                    isBaseLayer: false
                                    , yx: { 'EPSG:4326': false }
                                }
                            );

it does not work
                wms_l = new OpenLayers.Layer.WMS("Mérések",
                                wMS_ServiceURL,
                                {
                                      layers: wms_layer
                                    , request:"animate"
                                    , featurePrefix: featureprefix
                                    , viewparams: view_Params
                                    , aparam:"time"
                                    , avalues:"2014-02-01,2014-02-05"
                                    , format:"image/gif";subtype=animated"
                                    , format_options: "gif_frames_display:200;gif_loop_continuosly:true"
                                    , version:"1.1.1"

                                    , transparent: true

                                },
                                {
                                    isBaseLayer: false
                                    , yx: { 'EPSG:4326': false }
                                }
                            );
Can anybody help me?
