XnView Software

JPEG2000 support open file two methods :
1) full size
2) only windows resolution
this means what for example you opened image 4096x2304 , but you window or desktop resolution 2560x1440 оr 1920x1080 , in this mode decode images not as 4096x2304 , but as 2560x1440 or 1920x1080 , because detail smaller ...

Speed decoding JPEG2000 will be increase ?

This can add as separate plugin for tests )

When I can be try this ?
Currently I not known as this working and will I like it or not )
My format requirements :
1) compression speed , even on old PCs
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
please , make unifed modes in both ...

Yes , quality now it became better , but still lower as I want , quality still lower then in ACDSee Preo
You planed increase quality dithering in JPEG ?

Thak you ) this bug fixed )

Previously I was mistaken with link

Hi )
Please add this codec to XnView MP https://github.com/bitbank2/SLIC
I learned about this from my friend , he learned from here https://encode.su/threads/4141-Simple-L ... SLI)/page3

Hi )
If I use ACDSee Pro any version and I see JPEG2000 imagers , so I have this :
1) image size 4000x3000
2) in view set fit to window
and if window size or desktrop size 1000x750 , image load and view in progressive mode and decode as 1000x750 , if next I press full size - image reload with low ...

Please , add all this algorithms https://surma.dev/things/ditherpunk/ and will be learn which is better
In the end will better if this algoritms will be apply optionaly to all lossy or images with less colors
this for testing methods of dithering https://surma.dev/lab/ditherpunk/lab.html

Right , Dithering must be do use only for 1x2 1x1 1x1 or 2x1 1x1 1x1 or 2x2 1x1 1x1 , for 1x1 1x1 1x1 dithering not need use )
I also asked in JPEGLi https://github.com/libjxl/libjxl/issues/4146 , you can see what XnView MP and ACDSee Pro 5.0 with IDE_ACDstd 5.0.56.0000 reading file with differ , in ...

Which method compression in JPEG file was be used ? This very need for report , I mean what 1x1 1x1 1x1 or 1x2 1x1 1x1 or 2x2 1x1 1x1 )
And test was be do with classic JPEG compression methods or JPEG LI compression methods ?

Theme can close , because this resizer very not universal ) I do tests , and see what this resizers more often work bad then good

How I can fix this
Me not like what remains white in menu , how this fix ?
