[gdal-dev] Problem with gdalwarp and resampling_method

[Jan Tappenbeck]

  HI !

i will translate a tif-image between two systems and use following command

gdalwarp -s_src EPSG:25832 -t_src EPSG:31468 
D:\XXXX\Orthophotos\2616_5806_RGB.tif 
D:\XXXX\Orthophotos\2616_5806_RGB_GK.tif

then i get following message...

Usage: gdalwarp [--help-general] [--formats]
     [-s_srs srs_def] [-t_srs srs_def] [-to "NAME=VALUE"]
     [-order n] [-tps] [-rpc] [-geoloc] [-et err_threshold]
     [-te xmin ymin xmax ymax] [-tr xres yres] [-ts width height]
     [-wo "NAME=VALUE"] [-ot Byte/Int16/...] [-wt Byte/Int16]
     [-srcnodata "value [value...]"] [-dstnodata "value [value...]"] 
-dstalpha
     [-r resampling_method] [-wm memory_in_mb] [-multi] [-q]
     [-cutline datasource] [-cl layer] [-cwhere expression]
     [-csql statement] [-cblend dist_in_pixels]
     [-of format] [-co "NAME=VALUE"]*
     srcfile* dstfile

Available resampling methods:
     near (default), bilinear, cubic, cubicspline, lanczos.

when i modify the command to ....

gdalwarp -s_src EPSG:25832 -t_src EPSG:31468 -r near D:\XXXX\Orthophot ...
or
gdalwarp -s_src EPSG:25832 -t_src EPSG:31468 -r bilinear 
D:\XXXX\Orthophot ...
or
gdalwarp -s_src EPSG:25832 -t_src EPSG:31468 -r cubic D:\XXXX\Orthophot ...
or
gdalwarp -s_src EPSG:25832 -t_src EPSG:31468 -r cubicspline 
D:\XXXX\Orthophot ...
or
gdalwarp -s_src EPSG:25832 -t_src EPSG:31468 -r lanczos 
D:\XXXX\Orthophot ...

it resonse the same message and nothing will happen!

the image-informations are...
