Re: [mapserver-users] Specify resolution (or pixel size) in WMS requests
Hello, last december 2011 Astrid wrote a mail about the behaviour of RESOLUTION and DEFRESOLUTION. We tested again with MapServer 6.2 and here are the results. The size of the symbols, texts and lines was not like we expected. They were often too small. Have a look at the mail from 14. december 2011 http://lists.osgeo.org/pipermail/mapserver-users/2011-December/071077.html We tested with MAP.RESOLUTION=288&MAP.DEFRESOLUTION=72, SIZEUNINTS Meters, the scaled layers with SYMBOLSCALEDENOM 1. http://localhost/cgi-bin/mapserv62b1?map=/data/umn/resolution/map/resolution_test.map&MAP.RESOLUTION=288&MAP.DEFRESOLUTION=72"&VERSION=1.1.1&REQUEST=GetMap&SERVICE=WMS&LAYERS=notscaledPoint,scaledPoint,notscaledLine,scaledLine,notscaledPolygon,scaledPolygon,Polygon_with_symbols,notscaledLabel,scaledLabel&STYLES=&SRS=EPSG:31466&BBOX=2517600,5672315,2518960,5673675&WIDTH=2000&HEIGHT=2000&FORMAT=image/png&BGCOLOR=0xff&TRANSPARENT=TRUE&EXCEPTIONS=application/vnd.ogc.se_xml The behaviour of MapServer 6.0 and MapServer 6.2 is just the same. This time we have a demo project where we tried the different cases. You can download it at: UMN: https://svn.wheregroup.com/download/mapserver_resolution.zip PDF: https://svn.wheregroup.com/download/mapserver_resolution_pdf.zip Results: POINTS * scaled or not scaled Points/Symbols: displayed correct, scaled and notscaled are the same in the map LINES * scaled lines: displayed correct * unscaled lines: too small (1:2000, 1:5000, 1:1000), correct (1:2) POLYGON * scaled Polygone/Outline: displayed correct * not scaled Polygone/Outline: too small (1:2000), correct (1:5000, 1:1,1:2) * scaled or not scaled Polygone with symbols: displayed correct LABEL * scaled Label: too small * not scaled Label: too big (1:1000, 1:2000, 1:5000, too small (1:2) For us it would be good to get this problem solved, as at the moment we generate a copy of the mapfile for the print with symbol- and labelsize multiplyed with factor 4. It would be charming to solve the print with one mapfile. We could do testing and maybe I could look for sponsoring too. Is there someone else interested to solve this? Is there a ticket already?

Basically, I am looking for a way to something analogous to DEFRESOLUTION in a WMS request. The standard says, that a pixel is 0.28 mm x 0.28 mm (25.4/0.28 ~= 90.71 DPI).
