[Qgis-developer] Problems Displaying GeoTIFFs in QGIS 1.7.0

[Giovanni Manghi]

check the (a) raster properties and in "style" look for contrast
enhancement: if it is saved to something else than "no stretch" than it
can be the source of the problem. If a known bug of 1.7.

Save the option to "no stretch" and it works as workaround when you will
open any other raster.

Cheers

I viewed the same images in QGIS version 1.5.0 and saw the high quality images that I expected to see. Is there a problem with version 1.7 that degrades image quality?
