slow raster loading<br></font><br>On Tue, Aug 9, 2011 at 2:37 PM, Tim Sutton <<a ymailto="mailto:lists@linfiniti.com" href="mailto:lists@linfiniti.com">lists@linfiniti.com</a>> wrote:<br>><br>> Yes thats why I was asking if the file permissions exist to write the<br>> aux.xml. If they don't behaviour should be the same as prior to my<br>> native raster stats commits i.e. stats will be recalced each time you<br>> open a project / add a layer and trigger something that needs the<br>> stats.<br><br>Tim, and others,<br><br>By the way, there is a mechanism in GDAL to support storing .aux.xml<br>information in an alternative directory when the file cannot be<br>created on the target directory due to permissions, read-only media, etc.<br><br>This is enabled by setting the GDAL_PAM_PROXY_DIR option to<br>point to a directory where files can be written. If there is a place<br>known to QGIS that would be good for this, it might make
sense<br>to take advantage of this.<br><br>Best regards,<br>-- <br>---------------------------------------+--------------------------------------<br>I set the clouds in motion - turn up | Frank Warmerdam, <a ymailto="mailto:warmerdam@pobox.com" href="mailto:warmerdam@pobox.com">warmerdam@pobox.com</a><br>light and sound - activate the windows | <a href="http://pobox.com/%7Ewarmerdam" target="_blank">http://pobox.com/~warmerdam</a><br>and watch the world go round - Rush | Geospatial Software Developer<br>_______________________________________________<br>Qgis-developer mailing list<br><a ymailto="mailto:Qgis-developer@lists.osgeo.org" href="mailto:Qgis-developer@lists.osgeo.org">Qgis-developer@lists.osgeo.org</a><br><a href="http://lists.osgeo.org/mailman/listinfo/qgis-developer" target="_blank">http://lists.osgeo.org/mailman/listinfo/qgis-developer</a><br><br><br></div></div></div></body></html>
