Apply bilinear filter at 100% zoom for HiDPI monitors

Post by sacharja »

Hi,

I've seen some small improvement for some use cases:

- select a zoom factor of e.g. 170% on a HiDPI display in Windows 10 (Settings > Display > Advanced Scaling Settings)
- activate the following XnView MP setting "Zoom on HiDPI display: 1 image pixel equals to 1 monitor pixel" (image is correctly scaled)
- click on the opened image and hold the left mouse button, so that the image is shown with 100% zoom factor

Then there are artifects visible because no bilenear filter is applied. On a LowDPI Display this is correct, however on a HiDPI Display bilinear filtering is necessary for 100% zoom, because the image needs to be zoom in the background.

Would be awesome if bilinear filtering could activated on 100% zoom as well for HiDPI displays.

Thx, were you able to reproduce? Seems this is still open in 1.5.5:

On my 4k (windows scale factor 170% & XnView Zoom on HiDPI display):
1. Standard view with 109% zoom (zoom factor a result of automatic zoom fit to window)
109%.png

2. view with 100% zoom (pressing "-" in XnView until it shows 100%)
100%.png
3.
