<ul></ul><p>Hi,</p>
<p>Paletted and deflate compressed files works for me with QGIS 2.0.1 which comes with GDAL 1.9.2 on 32-bit Windows. Perhaps there is something wrong with the 64-bit GDAL 1.10.0. Try if you can do gdalinfo or gdal_translate with executables which are maybe in C:\\Program Files\\QGIS Dufour\\bin. I am not sure if that works, though. There can be troubles with paths.</p> QGIS Application - Bug report #8782: can't open compressed geotiff - missing codechttps://issues.qgis.org/issues/8782?journal_id=454312013-10-08T05:00:24ZDavid Striposgeo@stripfamily.net
<ul></ul><p>deflate works on 32 bit GDAL, but apparently not on 64 bit. I tested a deflate file against the 64bit gdal packaged with qgis 2.0.1 Dufur and it gives an error message that deflate is not supported. This might actually be a problem with the tiff lib rather than gdal itself.</p> QGIS Application - Bug report #8782: can't open compressed geotiff - missing codechttps://issues.qgis.org/issues/8782?journal_id=454322013-10-08T05:27:42ZDavid Striposgeo@stripfamily.net
<ul></ul><p>I just downloaded the latest release build of gdal from gisinternals.com (labeled release-1600-x64-gdal-1-10-1-mapserver-6-4-0). deflate compression is supported in this build. Apparently there is something wrong with the build packaged in Dufur.</p> QGIS Application - Bug report #8782: can't open compressed geotiff - missing codechttps://issues.qgis.org/issues/8782?journal_id=454412013-10-08T22:36:15ZGiovanni Manghigiovanni.manghi@gmail.com

<p>Only if you can reproduce the problem in OSGeo4W - although the standalone installers are made from OSGeo4W packages and should behave the same. They always are snapshots of OSGeo4W and OSGeo4W might already have newer packages. This is probably the case here too.</p> QGIS Application - Bug report #8782: can't open compressed geotiff - missing codechttps://issues.qgis.org/issues/8782?journal_id=455182013-10-10T20:32:17ZJürgen Fischerjef@norbit.de
