Title: Message Title

Tobias Warneke created an issue   GeoServer / GEOS-9177 external legend graphics problems using GeoServer 2.14 Issue Type: Bug Affects Versions: 2.14.3 Assignee: Unassigned Components: styling Created: 08/Apr/19 10:07 AM Priority: Medium Reporter: Tobias Warneke Due to a complex style, we want to use an externally generated image as a legend. Therefore we put it right into the style configuration as legend graphics. 1. The url is only recognized, if it ends with a valid extension (we use a dummy parameter &helper=legend.png). ExternalGraphicPanel (line 91) 2. The image size is fixed. That seems to be a problem, due to our legend graphics is generated and may vary in size. 3. Assume we used the legend url: http://192.168.10.115:8088/gm.gisserver/rest/projects/test_fh2_postgresql/reports/generate/simple?reportid=201.1000&reporttype=PNG&helper=legend.png then within the capabilities document the legend part is: <LegendURL width="160" height="144"> <Format>image/png</Format> <OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink" xlink:type="simple" xlink:href=""http://192.168.10.115:8088/gm.gisserver/rest/projects/test_fh2_postgresql/reports/generate/simple?reportid=201.1000&reporttype=PNG&helper=legend.png" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">http://192.168.10.115:8088/gm.gisserver/rest/projects/test_fh2_postgresql/reports/generate/simple?reportid=201.1000&reporttype=PNG&helper=legend.png"/> </LegendURL> You see, the workspace URL is attached in front of it (http://192.168.10.115:8088/geoserver/styles/test_fh2_postgresql/) 4. How is a GetLegendGraphic request formulated? We don't know the size of our generated image. We want to set with / height for geoserver generated legend graphics. If we put width / height = 20 into our URL, the complete external legend graphics is scaled to 20x20. Best regards Tobias Add Comment   Get Jira notifications on your phone!
