Re: [mapserver-users] Output Raster format
Hi Mapserver is not much like web processing service. However, something can be done with layer PROCESSING directives SCALE and LUT. There may be other options for customizing which I am not aware. http://mapserver.gis.umn.edu/docs/howto/raster_data/#special-processing-directives Sometimes I have been thinking that it would be nice to have an option to push aerial photos out through some sort of sharpening filter. -Jukka Rahkonen- Lähettäjä: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Puolesta David Martinez Morata Lähetetty: 3. kesäkuuta 2008 11:48 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: [mapserver-users] Output Raster format Hello!

Re: [mapserver-users] Output Raster format
Thanks! I read about procesing functions, but I don't really understand the functions :S I have a WMS for raster cartographyc fonds and I need to do more clear images. the colors in the images are strong colors and when I insert a shape I have some problems to clear show this shape. Any sugestions? Thanks 2008/6/3 Rahkonen Jukka <[EMAIL PROTECTED]>: > Hi > > Mapserver is not much like web processing service.

Re: [mapserver-users] Output Raster format
Hi,
Try adding something like
PROCESSING "LUT=0:0,255:200"
It should give an linearly lightened image. Have a try and play with the LUT
input/output values, perhaps you'll get a more usable output. By using separate
LUT inputs you can control red, green and blue separately. If you want to use
WYSIWYG tool for colour adjustment take a sample image into GIMP, use curves
tool and save the GIMP curve file once you are satified. "PROCESSING LUT="
accepts the curve files saved from GIMP.
GIMP is not meant for big geospatial images. Use some reasonably sized image
excerpt for adjusting colours with it.
