Dear readers of this list,
currently I am trying Pixel, an image manipulation application by Pavel Kanzelsberger (http://www.kanzelsberger.com) available for all major platforms.
I exported a Pixel image as a tiff-image using that application; you can see the file at http://www.linopus.de/debian/pixeltest.tif However, on Debian Sarge GNU/Linux using libtiff 3.7.2 pixeltest.tif is not rendered correctly in applications using libtiff (The Gimp, Scribus, Konqueror etc.). For the incorrect rendering see a screenshot at http://www.linopus.de/debian/pixeltest-konqueror.png.
It is rendered correctly, however, on the same system by XnView (which, as far as I now, does use its own libraries). Additionally, pixeltest.tif is rendered correctly by Adobe PhotoShop 6 and Deneba Canvas 9 on a Windows system.
Therefore I am inclined to believe that libtiff is the reason for the incorrect rendering. If this is a known issue I would like to know if there is a workaround, if not, I would like to report it as a bug.
