I am trying to produce a time series animated GIF, with an annotation at the bottom of the map that shows the time. Thanks to an example from Charlton Purvis found by a search of previous postings on making an animated GIF (modified to use a single layer, changing the filter to select for the data that is in my current time step):
http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0304/msg00482.h tml And a Wiki entry from Jeff McKenna about making a copyright notation: http://mapserver.gis.umn.edu/docs/faq/copyright-layer I have the basics, that is, an animated time series, with a statically placed text entry at the bottom (at a map-specific point, rather than a lat lon). However, the annotation layer can only display a single entry, not one that is updated with the time step. I am wondering how to do this, if I can modify the property of the annotation layer, or if I need to create a point of some sort from a dynamic postgis call. I can't seem to set the TEXT portion of the feature via php mapscript. Anyone have any ideas? (code and mapfile follow) foreach ($gifmaps as $thismap) { $thislayer = $amap->map->getLayerByName('stream_stat'); $filter = " projectid = $projectid and thismetric = '$thismap' "; $listobject->querystring = " select count(*) as numrecs from proj_group_stat "; $listobject->querystring .= " where $filter "; $listobject->performQuery(); $numrecs = $listobject->getRecordValue(1,'numrecs'); #$annotlayer = $amap->map->getLayerByName('copyright'); #$annotation = $annotlayer->getFeature(1,-1); if ($numrecs > 0) { $thislayer->setFilter($filter); $thislayer->set("status",MS_ON); #$annotation->set("TEXT", $filter); $image[$i] = $amap->map->draw(); $image_url[$i] = $image[$i]->saveWebImage(MS_GIF,1,1,0); $file_path[$i] = $amap->map->web->imagepath . substr(strrchr($image_url[$i], "/"),1); $anim_files = $anim_files . '"' . $file_path[$i] . '"' . " "; $i++; print(" Adding <i>$filter</i>, $image_url[$i] <br>"); } } // Create a unique filename and URL for the animated GIF output $anim_name = "anim".substr(strrchr($image_url[1], '/'),1); $anim_path = '"' . $amap->map->web->imagepath . $anim_name .'"'; $anim_url = $amap->map->web->imageurl . $anim_name; print("Creating $anim_path <br>"); $cmd = $anim_gif_cmd . " -o " . $anim_path . " " . $anim_files; print("Using: $cmd <br>"); system($cmd); # annotation layer LAYER NAME copyright STATUS ON TYPE annotation TRANSFORM false FEATURE POINTS 150 180 #this is the position of the text in image coordinates (pixels) END TEXT "From 2007/01/01 to 2007/06/30" #this is your displaying text END CLASS LABEL #defines the font, colors etc. of the text FONT "arial" TYPE TRUETYPE SIZE 10 BUFFER 1 COLOR 0 0 0 BACKGROUNDCOLOR 255 255 255 FORCE TRUE END END END Robert W.
