Resize Filter causes image to shift color (more contrast)
When Resize Filter is enabled, the color of the image changes.
Below is an example.
The image is a pure 128,128,128 grey image.
After enabling Resize Filter, image becomes 136,136,136:
It doesn’t matter which interpolation I use, they all cause this issue.

Does your image contain an ICC profile? If it does I think we are having the same problem.
ICC profile colors seem to be ignored if resize filter is on.
Example image (download and open it in NeeView):
I did some testing and tried enabling susie’s ifjpeg plugin. The problem doesn't exist with susie as it probably applies the ICC profile to the image before sending it to NeeView.

reporter Nope, my image don’t have ICC.
But I can only reproduce this bug with greyscale (i.e. 1 channel only, 8bit in total) image (bmp, jpg, or png), just like the one you posted.
Below is another one I used.

I can’t reproduce the problem using your image. (sha1= 96a47a49264e1e18352b3804645b306dea5ca355)
The color is 128,128,128 at any point (100% zoom / 105% zoom / resize enabled / resize disabled)

-
reporter Yeah, I use Win7
