Re: [mapguide-users] Fusion legend performance fixes in the future?
Hi Jackie, Thanks for the reply. I am using AIMS 2013 with IE 8 and that is not what I'm seeing. Using Fiddler, I can see up to 300 OPERATION=GETLEGENDIMAGE calls in a row upon zooming in to a level where all layers are available. Each change in scale factor results in a re-request of each legend image. Here's a typical request: GET /mapserver2013/mapagent/mapagent.fcgi?OPERATION=GETLEGENDIMAGE&SESSION=a4daacfe-437a-11e3-8000-005056945141_en_MTI3LjAuMC4x0AF20AF10AF0&VERSION=1.0.0&SCALE=4622336.17439434&LAYERDEFINITION=Library%3A%2F%2FGVEA_AIMS%2FLayers%2FLand%2FGVEA%20Offices.LayerDefinition&THEMECATEGORY=0&TYPE=1&CLIENTAGENT=Fusion The legend widget uses the MapGuide.js getLegendImageURL function which in turn is using the GETLEGENDIMAGE operation. Is there something that I'm missing?

Re: [mapguide-users] Fusion legend performance fixes in the future?
Unless your users are in IE 7 or older (*shudder*), Fusion will render the majority of the icons on the web tier inline with the layer JSON by leveraging the Data URI feature that is supported by all browsers from IE8 onwards, eliminating the majority of GETLEGENDIMAGE request spam, the main performance bottleneck of the Legend widget. - Jackie -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Fusion-legend-performance-fixes-in-the-future-tp5087026p5087056.html Sent from the MapGuide Users mailing list archive at Nabble.com. ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
[mapguide-users] Fusion legend performance fixes in the future?
Hi All, On a current project, we have a map with about 220 layers and many of those layers are thematic (but none with over 10 themes). We have found that the legend widget is the single largest performance drag on the application. For instance, we might see an application rendering time of 30 seconds when the legend is enabled and 5 seconds when it is not. We can identify several reasons why the widget is so slow. An example is that it calls the GETLEGENDIMAGE operation for every layer and theme swatch whether it is visible (expanded) in the legend or not for a given scale factor. Whereas the AJAX viewer will request those images only when the layer or them is expanded. That includes at the time of the expansion. I'm sure that others have had similar issues with the Fusion legend and I am wondering if anyone is actively working on re-tooling the legend widget? I looked through TRAC and do not see any active tickets pertaining to this topic.

Re: [mapguide-users] Fusion: Zoom to selected features with multi selection
Hi Jackie, thanks fpr your reply. Good to know that I'm not the only one with that wish. But it's a trac which is intact for 3 years! And the milestone is stucked in 2.3. Are there any intentions to work on that further? -torrini -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Fusion-Zoom-to-selected-features-with-multi-selection-tp5086124p5086929.html Sent from the MapGuide Users mailing list archive at Nabble.com. ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
