Ah, great! That fixed it :-)
Is there an official 1.11.3 release in the works? It's a bit of hassle for
me to integrate it into our build system here, so if there's a new official
version out soon I probably won't bother to integrate the current snapshot.
Thanks so much for your help, Even!

When using the same image in GeoTIFF with overviews, it works correctly,
which may indicate something with the ECW drivers. I suppose it must be
something triggered by something weird I'm doing though, or else I would
think that other people would have the same problem.
The weird thing is that if
Thomas,
2 suggestions to help narrowing down the issue :
- try gdalwarp of GDAL 2.0 that can select the most appropriate overview
given the target resolution / raster size
- try with the ECW translated as a GeoTIFF to check if it isn't an issue with
the ECW driver itself.

Argh, I managed to send it while editing :-)
Anway, input to this code section is the wanted overview level and the
derived scale factors in X- and Y-direction. Output is the vrtDS dataset
that is used in the GDAL Warp api later.
Are there any obvious mistakes I've made here?
I see that in GDAL
Hi,
I am having a bit of trouble with warping a dataset (an ECW file) with
multiple overviews. The base file is huge, so I am selecting the overview
that matches closest to my output resolution and makes an in-memory VRT of
this, consisting of the overview bands of the original image.
This seems
