XnView Software

Tiff pic that was ok in 1.95.4 does not show correctly in 1.96.2 - thumbnail and the preview looks like b&w noise.

Hello !

• Confirmed here, it's shown in 1.96.2 as a granite area…
- It works in old versions 1.8… 1.9… also in Universal Viewer, Imagine (as Total Commander “Lister” plug-in)…

Confirmed using 1.96.2

The image is somewhat weird as far as compression is concerned. It is a 8 bit palletized image with less than 256 colours using NO COMPRESSION. Repacking it again with Irfanview, for instance, fixes it and reduces filesize from 1.3MB to 620 KB, using LZW compression and 550.2KB using DEFLATE (ZIP) compression.

I don't know why XnView fails to load it though.

I don't know about weird , but out of 300 tiffs in folder I would say 20% displays wrong (picture and thumbnail). All of them was written by Silverfast which I am using wit my scanner. I never had a problem with those files except in XnView which seems to be very picky with tiff files. Sometimes does not display tiffs in folder at all, not even thumbnails just empty folder in browser. Then Tiffs appearing in the folder if I chose from the menu filter/all and then I can switch back to the filter/images only then for a while everything is ok again, but that just weird behavior.

No matter what XnView is a piece of great software, keep up the good work and great support.

BTW, nconvert can change it to a normal-looking png.

It works also with xnShell but for some reason I can't see it correctly in 1.96.2, when in 1.95 everything was fine.
