[0.99.6] "Fit image to window" incorrect on retina

[lolmaus]

Hi! Using 0.99.6 64-bit on Windows 10 Pro.

When I use "Auto image size" → "Fit image to window" on a non-retina display, the result is correct:



However, when I move the window to a retina display, the image is resized incorrectly. Here's an example for a 150% retina factor:



Apparently, some part of XnViewMP is accounting for the retina factor in its calculation while another part doesn't.

I would like to add that this hasn't been the case previously. This bug is a regression introduced at some point.

it was always like, if you click on 'fit image to window'?

I don't understand the question, please rephrase.

I would like to add that this happens only to images that are smaller and should be stretched in "Fit image to window" mode. Images that are larger and should be shrunk are fine.

Perhaps you had 'settings>View>Zoom on HiDPI screen...'?

Yes, unchecking that checkbox resolved my issue, thanks!

But I still think there's a problem with it enabled. If that behavior is intentional, why does it only affect smaller images?

On HiDPI screen, when enabled the image size doesn't use pixel scaling

Well, this option breaks "Fit to window" for smaller images, doesn't it?

No, why? Perhaps i don't understood the problem?
