Unfortunately, having to deal with ECW is not a matter of being maniacs
of proprietary formats but of many useful free geoinformation provided in
ECW format. Actually, not having ECW (or mrsid) support can be a cause
of not using qgis at all.
What about designing a separate external tool that would use gdal 1.6
for a fast conversion
of ECW to a fully gdal 1.7 supported compressed format? This would be
a temporary solution while
gdal finds a better solution for ECW support (best) or while ECW is
dropped by producers
of public geodata.
What format would you suggest to replace ECW ? JPEG2000 ? Is OpenJPEG
mature enough ?
gdal 1.8 will feature an openjpeg driver, I didn't have time to test it
but it supports stream and levels.
