XnView Software

In viewing a folder of tif images, some images (and their thumbnails) are displayed with what appears to be histogram equalization.
When I display these images in mac Preview app or using Photoshop, they display normally.
Also if I export the image using Preview app without making changes the subsequent image is displayed correctly.
Do you know the reason for this?

could you send me a sample?

how to send you image?
can't seem to attach one here...

Here are the image examples...one displays correctly (roi.0204746100.tif) the other not (roi.0204753800.tif).
They both display fine in Preview and Photoshop, but not in xnviewmp

Nice acidous colors. Screens made in XnView Classic 2.35. In other programs capable of opening .tif lower picture looks green-on-black like the one above. i know you here are discussing MP flaws, but MP users often post in Classic forum, so I thought, why not?

tiffinfo.exe needs jpeg62.dll (Jpeg for Windows » Binaries) and zlib1.dll (Zlib for Windows » Binaries).

ok, i found the problem, min/max sample value not correctly readed....

You mean XnviewMP does not read the min max values correctly?
If so, will it be fixed in the next version?
When is next version?

Thanks.

Windows users of XnView Classic already received repair in v2.36.

I'm using macbook pro w osx 10.8.5
xnviewmp version 0.79 x64 (Mar 22 2016)

looking forward to this fix.
