[D2D] Loss of detail (blur) for images scaled down

rehael » January 26th, 2019, 1:19 pm

Hi.

I noticed that after changing Rainmeter to 4.3.0.3729 one of the skins I use has blurry images.

HWA doesn't have impact on this – result it the same for HW on or off.

Left is 4.2.3111– right is 4.3.3729

The moon image is blurred and some details are lost. Same for the clouds – especially the bottom one with the rain – it isn't as crisp in 4.3 as it was in 4.2.

Is there some setting which could enable the crisp scaling?

The skin is https://www.deviantart.com/vclouds/art/VClouds-Weather-2-179058977

Any improvement if you remove the AntiAlias=1 option from the Image meters?

Looks like AntiAlias doesn't have any visible impact in 4.3 on Meter=Image. I created an example RMSkin and here's how it looks like on my machine:

4.2:

4.3:

skin:
Betatest43-AntiAlias_1.0.rmskin

We might be splitting hairs over some pixels here, but you wanted to know if anything you see that is "different" for you when using Rainmeter 4.3, so, well, here's that. :)

We will look into it... Thanks for reporting.

I actually think this is some difference with how "sizing" is done, not so much anything with "antialias". If I use the image(s) without sizing them, they seem to be the same in 4.2 and 4.3.

But with sizing, you are right...
