[mapserver-users] MapServer and 24bit Images

[Carlos Ruiz]

José,

Yo presento imágenes de 3 bandas como WMS sin problema alguno. Debo decir que no uso de OUTPUTFORMAT en estos casos ya que desde los parámetros del URL se especifica el formato de salida (parámetro FORMAT).


Por lo que veo, estás queriendo acceder a una capa tipo raster desde una base de datos en Postgres.

¿ Integraste una capa raster a Postgres (gracias a que en las ultimas versiones de PostGIS se incluyó lo que era el proyecto WKTRaster) ? ¿ O estás queriendo acceder a un archivo raster directamente ? 


Desconozco si las directivas PROCESSING aplican para una capa raster en PostGIS, nunca he intentado trabajar con esto.


Saludos desde México



José,

I work with 3 bands images as WMS with no problem at all. I must say that i didn't use the OUTPUTFORMAT because I can specify the output format in the URL (FORMAT parameter).

As I see, you want to show a raster layer from a Postgres database.

¿ Do you added a raster layer into Postgres (thanks to the latest versions of PostGIS which added the WKTRaster project) ? or ¿ Do you want to access directly to a raster file ?

I don't know if the PROCESSING directives apply to a PostGIS raster layer, I've never tried to work with this.


Cheers from México

 
IC Carlos Ruiz

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
