[Qgis-user] Blocking issue with tilted huge images

[Alexander Bruy]

Hi Stéphane,

seems this is actually not QGIS issue but GDAL one. See this
ticket in QGIS tracker https://hub.qgis.org/issues/1722 and another
in GDAL http://trac.osgeo.org/gdal/ticket/2076

> load such an image, QGIS (tested with 1.8 and 2.x) just freezes.
> Investigation shows this occurs only when the World file contains a rotation
> (is it trying to resample the complete image at loading time?). Manual
> edition of the World file to remove the rotation leads to smooth loading of
> the image.

> Can somebody help or suggest further tests?
