Hi people,
I´m trying to display a raster layer from a tileindex file (.shp). The
source rasters for this shapefile are jpeg with the following info:
Driver: JPEG/JPEG JFIF
Size is 6401, 4001
Coordinate System is `'
Origin = (-15999.111000000001000,100001.744000000010000)
Pixel Size = (2.500000000000000,-2.500000000000000)
Corner Coordinates:
Upper Left ( -15999.111, 100001.744)
Lower Left ( -15999.111, 89999.244)
Upper Right ( 3.389, 100001.744)
Lower Right ( 3.389, 89999.244)
Center ( -7997.861, 95000.494)
Band 1 Block=6401x1 Type=Byte, ColorInterp=Gray
The OUTPUT objects:
IMAGETYPE png32
OUTPUTFORMAT
NAME gif
DRIVER "GD/GIF"
MIMETYPE "image/gif"
IMAGEMODE PC256
EXTENSION "gif"
TRANSPARENT ON
END
OUTPUTFORMAT
NAME jpeg
DRIVER "GD/JPEG"
MIMETYPE "image/jpeg"
IMAGEMODE PC256
EXTENSION "jpg"
END
OUTPUTFORMAT
NAME png32
DRIVER "GDAL/PNG"
IMAGEMODE RGBA
TRANSPARENT ON
END
The layer object:
LAYER
NAME vinte_cinco_alta
METADATA
"wms_title" "vinte_cinco_alta"
END
STATUS ON
TILEINDEX '25000_alta.shp'
TILEITEM 'location'
TYPE RASTER
#PROCESSING "SCALE_1=3,0"
#PROCESSING "SCALE_2=3,0"
#PROCESSING "SCALE_3=3,0"
#PROCESSING "SCALE=AUTO"
#PROCESSING "COLOR_MATCH_THRESHOLD=1"
#PROCESSING "BANDS=2
OFFSITE 255 255 255
TRANSPARENCY ALPHA
PROJECTION
"init=epsg:27492"
END
DEBUG ON
MINSCALE 10000
MAXSCALE 26000
END
My prob is that i can´t force mapserver only to render the black color in
the rasters (i tried changing several parameters in the layer object, and
using different output declarations). If it´s possible can u show it to me?
The output format isn´t important, just wanna get fully transparent layers
(in colors grey and white, keeping black).
Thanks in advance!
Cumps, Pedro Mendes
