[gdal-dev] Problem to merge 2 images

[Jan Tappenbeck]

  hi !

i have got two images to merge and convert into ecw - but i only get a 
error-message and a black image.

i send following command:


gdal_merge.bat -of GTiff -o 
D:/GDAL_Projekte/xxxxxxxxxx/xxxxxxxxxx_gesamt.tif 
D:/GDAL_Projekte/xxxxxxxxxx/xxxxxxxxxx_300_nord_geo.tif 
D:/GDAL_Projekte/xxxxxxxxxx/xxxxxxxxxx_300_sued_geo.tif

gdal_translate -of ECW -co LARGE_OK=YES 
D:/GDAL_Projekte/xxxxxxxxxx/xxxxxxxxxx_gesamt.tif 
D:/GDAL_Projekte/xxxxxxxxxx/xxxxxxxxxx_gesamt.ecw

and here are the image-infos and the message - can anybody help me?

reagards Jan :-)
