I was scanning a picture in windows to the tif-format. In windows there is a thumbnail that shows the picture ok. I also think an icc-profile is in the picture. I can't scan the picture at this resoluation under linux with sane. I would like to scan to tif since it puts an icc-profile in the file then and if I want to scan at 48 bits/pixel, I think that tiff is my only choice with the software I'm using. I'm trying to convert the picture to png under linux (and hoping to also put the icc-profile in the png), but it seems libtiff (I suppose) can't display it correctly and the conversion to png (using imagemagick's convert) also doesn't work.

When I try to view the original image, only a part of the image is displayed and there is an error message when I request info about the original tif-fil(output of tiffinfo):

If only part of the image was displayed then there must have been an internal error in the software. The problem could be due to running out of memory or temporary disk space. Libtiff does not display images (other than the tiffgt utility) so I assume that you were using additional software (ImageMagick ?) to view the image.

It's quite a big file (108 MB). I saw that the error has been mentionned in this mailinglist (in January or February).

If you can make this file available for download, I will be happy to download it in order to check that the file is ok, and verify that GraphicsMagick (similar to ImageMagick) can load and convert it ok.
