I have a multipage TIFF with these properties.

: xnview_tiff_properties.png (19.8 KiB) Viewed 935 times

Opening the file displays this:

: Xnview_convert_color.png (5.5 KiB) Viewed 935 times

Why?

Hi Peter (-:

The color space of your TIFF file is YCbCr. XnView has to convert the image to RGB in order to display it.

BitsPerSample = <8,8,8>
PlanarConfiguration = 1, 2
Compression = 1 (none), 5 (LZW), 7 (JPEG)
PhotometricInterpretation = 6 (YCbCr)
