Ticket #2432 (closed task: fixed)
PAM proxy mechanism should work for overviews too
|Reported by:||warmerdam||Owned by:||warmerdam|
When GDAL_PAM_PROXY_DIR is set, it should also be used for creation and preservation of overviews (.rrd or .ovr). This appears not to be the case.
gdaladdo --config GDAL_PAM_PROXY_DIR /home/warmerda/proxy_db --config USE_RRD YES --config HFA_USE_RRD YES utm.png 2 ERROR 6: The PNG driver does not support update access to existing datasets. GDAL: GDALOpen(utm.png) succeeds as PNG. GDAL: GDALDriver::Create(HFA,utm.aux,512,512,1,Byte,0x7ffff3a78590) ERROR 4: Creation of file utm.aux failed. Overview building failed. GDAL: GDALClose(utm.png) GDAL: GDALDeregister_GTiff() called.
It also does not work for .ovr files.
