In case anyone else wants the createLegendIcon to return the image based what would be drawn at the current mapscale, here is what I did.
In the mapserver 7.0.4 source code, mapscript/php/mapscript_i.c line 1116 has scale_independant hard coded to MS_TRUE. I changed it to MS_FALSE, recompiled and have the behavior that I was expecting.

Do not click links or open attachments unless you know they are safe. I am finding that createLegendIcon returns a different legend item than what is used in the map output when using scaledenom in the style. Below is a test script that produces what I am talking about. The script will create 4 images. map_scale_873.png -> map->draw output with a 873 scaledenom map_scale_2618.png -> map->draw with a 873 scaledenom legimg_scale_873.png -> createLegendIcon output with a 873 scaledenom legimg_scale_2618.png -> createLegendIcon output with a 873 scaledenom I was expecting that the legend image at the 873 scale, legimg_scale_873.png would match the map output, map_scale_873.png. Can anyone see a problem, is this a bug, or is this expected behavior? <?php $mapstr = <<<EOT MAP NAME AERIAL EXTENT 100 100 400 400 SIZE 100 100 UNITS FEET LAYER NAME 'TEST' STATUS ON TYPE LINE FEATURE WKT 'LINESTRING(250 250, 250 500, 500 500, 500 250,250 250)' END CLASS NAME "Boundary" STYLE WIDTH 4.0 MAXWIDTH 6.0 COLOR 150 255 150 MAXSCALEDENOM 1000 END STYLE WIDTH 2.0 MAXWIDTH 2.0 COLOR 0 0 0 PATTERN 20.0 10.0 5.0 10.0 END MAXSCALEDENOM 1000 END STYLE WIDTH 4.0 MAXWIDTH 4.0 COLOR 150 255 150 MINSCALEDENOM 1001 END END END END END EOT; $map = ms_newMapObjFromString($mapstr); $map->selectOutputFormat('png'); $img=$map->draw(); $name=round($map->scaledenom); $img->saveImage("map_scale_$name.png"); $tmpLay =$map->getLayer(0); $tmpclass = $tmpLay->getClass(0); $tmpImg = $tmpclass->createLegendIcon(50,50); $tmpImg->saveImage("legimg_scale_$name.png"); $map->setextent(200,200,300,300); $img2=$map->draw(); $name=round($map->scaledenom); $img2->saveImage("map_scale_$name.png"); $tmpImg->saveImage("legimg_scale_$name.png"); ?> Thanks, Paul _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org <mailto:mapserver-users@lists.osgeo.org> https://lists.osgeo.org/mailman/listinfo/mapserver-users <https://lists.osgeo.org/mailman/listinfo/mapserver-users>
