[mapserver-users] MapServer and 24bit Images

[José Pedro Santos]

Dear Steve, 

I try to do that but didn't work. The image appear all black. I use the Processing directive for the 3 bands and also I remove to test but nothing happen. Can be a problem of image...
To test in the browser if I put Format=image/png:mode=24bit don't work, the error said that is not supported, but If I use FORMAT=PNG24 that work but the image came all black. I'm using the last version of MapServer 6.2.0.

Also with output and without output the image appear all black. I have the image store in PostgreSQL DB with 145MB size.  

Any idea? 

Best Regards
José Santos

I’m assuming you’re using MapServer 6.x… If so then your output format may be the issue. GD doesn’t support 24-bit output, just 8-bit. Try deleting the OUTPUTFORMAT
and setting IMAGETYPE PNG24 and see if that works.

Hi Steve,




Thanks for the information. Basically I want only to display the layer (as WMS service) in the browser for testing or a real client. The layer have 3 bands and is a 24bit image



My MAPFILE is this one(OUTPUTFORMAT and LAYER parameters):



OUTPUTFORMAT # Parameter Outputformat

 NAME png24

 DRIVER "GD/PNG"

 MIMETYPE "image/png;mode=24bit"

 EXTENSION PNG

 IMAGEMODE RGB

END # End parameter Outputformat



LAYER # beginning of the layer parameter

 NAME "fapartest"

 TYPE RASTER

 STATUS ON

 DATA "PG:host=localhost port=5432 dbname='mydb' user='postgres' password='****' schema='public' table='mytable' mode='2'"

 PROCESSING "NODATA=0"

 PROCESSING "SCALE=AUTO"

 PROCESSING "BANDS=1,2,3"

.........



I don't have class parameter since I don't want to classify the map just visualize the information. Any idea?



Best Regards and thanks,



José Santos
