[postgis-users] Raster2pgsql.py Possible No Data Problem

[Andreas Forø Tollefsen]

Hi. Sorry. I was confused and used the Python 2.5.

Now i get some other errors when using python 2.6. Could it be my setup
which is not correct?

C:\Python26>python raster2pgsql.py -r
c:\prio_grid\source\mountain\mean_mnt_bin.
tif -t mountain -s 4326 -I -o mountain.sql
Traceback (most recent call last):
  File "raster2pgsql.py", line 1036, in <module>
    main()
  File "raster2pgsql.py", line 999, in main
    gt = wkblify_raster(opts, filename.replace( '\\', '/') , i, gt)
  File "raster2pgsql.py", line 941, in wkblify_raster
    summary = wkblify_raster_level(options, ds, options.overview_level,
band_ran
ge, infile, i)
  File "raster2pgsql.py", line 901, in wkblify_raster_level
    hexwkb += wkblify_band(options, band, level, xoff, yoff,

ock_size, infile, b)
