Hi, GDALWarpOperation.ChunkAndWarpImage was reported to be extremly slow on larger geotiff (over 1GB). Is it possible that it is much slower with respect to GDALRasterIO() even without reprojection? Should I return to 'manualy' reading data via GDALRasterIO() + fidling with data extents and cells alignement? I thought that GDAL ChunkAndWarpImage will do it even faster, possibly knowing better (?) various formats nature.
Is there way to tune somehow performance? Currently no reprojection and GRA_NearestNeighbour. Still the same code which I posted before http://trac.osgeo.org/qgis/browser/trunk/qgis/src/providers/gdal/qgsgdalprovider.cpp?rev=15400#L625 Thanks for help.
