[mapserver-dev] strange behavior when size != gif size (UMN 5.4.2)

[Steve Lime]

I will... In your version line there's 'SUPPORTS=RGBA_PNG' which is the signature for
the experimental PNG support. Wonder what versions are used by mapserver and then
GD? Does IMAGETYPE JPEG work for you?

Can you check your output with a GetMap-Request using &FORMAT=image/png?

I'm using the cgi-bin folder from the "Mapserver 5.4.2 release" that is
packed in the ms4w_3.0_beta6. downloaded from maptools.org

here is the mapserv -v result

MapServer version 5.4.2 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
OUTPUT=PDF
 OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE
SUPPORTS=ICO
NV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT
SUPPORTS=WFS_SERVER
SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI
SUP
PORTS=THREADS SUPPORTS=GEOS SUPPORTS=RGBA_PNG INPUT=JPEG INPUT=POSTGIS
INPUT=ORA
CLESPATIAL INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE
