[mapserver-users] Mapserver seem change the line size in raster dataset

[Andrea Peri]

Hi Jukka.

This is a direct getmap over our wms

http://www502.regione.toscana.it/ows2/com.rt.wms.RTmap/wms?map=owstopoweb&version=1.3.0&map_resolution=91&TRANSPARENT=true&LAYERS=rt_topoweb.800k.rt&STYLES=&CRS=EPSG:25832&SERVICE=WMS&REQUEST=GetMap&FORMAT=image/png&BBOX=563561.9927077,4809257.3212631,817953.27072102,4878814.3834541&WIDTH=1302&HEIGHT=356

The raster is setting with this layer mapfile:


  OUTPUTFORMAT

    FORMATOPTION "INTERLACE=OFF"
    FORMATOPTION "QUANTIZE_DITHER=OFF"
    FORMATOPTION "COMPRESSION=6"  # Compression: 0=no compression,
9=best, 6=default compression
    FORMATOPTION "QUANTIZE_FORCE=ON"
    FORMATOPTION "QUANTIZE_COLORS=256"
   TRANSPARENT ON
  END
