This is Lena in grayscale, downscaled and converted to 16-bit linear colorspace.
The PNG file was created out of the PGM file using OptiPNG. Any ...

YCbCrSubsampling in EXIF is not updated
Hello,
I noticed that XnView does not update the YCbCrSubsampling field in EXIF after a lossless JPEG rotation. My digital camera (as well as most others) create JPEGs using chroma subsampling 4:2:2, which in EXIF is encoded as (2,1). After a lossless 90' rotation this should become (1,2), yet ...

Incorrect display of 16-bit raw PNM
Hi,
I noticed that the raw PNM formats (both PGM "P5" and PPM "P6") that have MAXVAL=65535 are displayed incorrectly. I believe you somehow get the endianness wrong, because I'm seeing the least-significant 8 bits from the 16-bit image.
If MAXVAL is anything less than 65535, or if the format is ...

Display the "rule of thirds" grid in the crop rect
Dear Mr. Gougelet,
I am so happy to see XnView getting better and better with every new release!
I wonder if you could implement somehow the display of the rule of thirds grid while cropping. I am thinking about a checkbox, or a popup menu check option, that could toggle this grid. It could come ...
