XnView Software

For fix need set as here )

I understand what need uncheck ) now work normally )

Maybe , but in ACDSee Pro and other programs and browser , this work normally , because I think what this bug in XnViewMP , this is avatars , that's why DPI in this images not recalculated , besides in other images this bug not detect for example in this images all correctly )

Yes , this so , but you need remember what JPEG never not was be lossless , and this means what we can say only quality in lossy mode , and because yes , values from 0 to 100 where 100 maximum quality of lossy quality ) , but in WebP available both mode , lossy and lossless , however quality range ...

Maybe , but then need modify value Quality to Lossy quality , I think what if this do, users will more clear )

Hi )
I can not understand why in WEBP quality 100% does not mean lossless quality, but select lossless quality means lossless quality, why this so?

2) decompression speed , even on old PCs
3) compression force , I wait what this format will smaller than JPEG XL , but faster than JPEG XL same ...

Thiss so and will leaved ? Or we recive unifed filters for risizer and viewer ?
Also , I want understand , what for in resizer avaiable cubic with low quality and not replaced to bicubic with better quality ) and what for in viewer absent lanczos2 mode and mitchel
