can't open compressed geotiff - missing codec

[qgib]

Author Name: David Strip (@Llaves)
Original Redmine Issue: 8782
Affected QGIS version: 2.0.1

---

Adding a compressed geotiff layer produces an error message

    <filename> is not a supported raster data source
    Cannot open TIFF file due to missing codec

This same file will display in tiff viewer or browser, gdalinfo shows its properties, and if I uncompress the file, the uncompressed version will open in qgis.

I have now tested LZW and PACKBITS. Both are successfully opened by qgis 2.0.1
The file I have been testing against is a paletted file, which is no valid for the remaining compression modes.

Hi,

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.

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.

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.

seems then an issue in the osgeo4w 64 bit packages. Please file your notes here:

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.
