XnView Software

On the Saturn rings. I attached an image with side-by-side comparison.

Try downscale to e.g. 1806x961 pixels. You can see the output image in the first post: download/file.php?id=5149&mode=view

Still reproducible in XnView: MP 1.3 (and also in XnResize, btw).

The posterized image you see in my post is the downscaled version of the original. I don't see any artifacts on the original image:

Downscaling an image with gamma correction posterizes dark areas. See the attached image (50% size of the original).

To reproduce, downscale an image with "Use gamma correction" enabled.

After "Save as", status bar shows file size of the saved image instead of the original file size.

To reproduce:
1. Open an image in view mode. The status bar will show the file size of the image.
2. Use "Save as..." (the format doesn't matter)
3. The status bar ...
