Re: [Qgis-user] qgis 1.7 geotiff problem
Hi, I can confirm this problem with ecw raster. The workaround is fine (ubuntugis 64bits in a debian chroot).

[Qgis-user] qgis 1.7 geotiff problem
Dear list, I have some very large geotiff-files (up to 10 GB) from satellite imagery that I need to load into QGIS. To speed up the rendering, I created pyramids on those images with gdaladdo. In QGIS 1.6 this worked very fine and the images where loaded (after adding them with "Add Raster Layer") within a few seconds. Now, after I updated to QGIS 1.7, it takes several minutes to load the images into QGIS with "Add Raster Layer" (after being loaded, however, everything works fine and I can zoom in and out without any time-consuming rendering processes). Anyone has an idea why QGIS 1.7 takes so much time to load the images, as it was working fine in QGIS 1.6? I am using QGIS on Ubuntu 10.10 64bit.
