But where ? For Encode or for decode ? I here sayding about files decoding process , you as I see sayding about files encoding process

That's why I asking you add this for decoding optionaly

I mentioned the write/encode setting for Jpegli hoping that Piere might consider a similar option for reading/decoding.
We have to wait for his response.


Thank you )
By the way , if do based "Floyd-Steinberg dithering " for High color and True color me this fully suitable ) because quality ...

I ask do as here , why this so hard do ?
Simply add tab with settings as reading JPEG , with dither or without dither , and if with dither then level and method as do dithering , this will can improve XnView

I can not understanding , why in this topic we say about process ENCODING , I all topic try sayd about DECODING process and this settings in XnView MP absent , I can not set as need decoding JPEG , I can set as encoding to JPEG , but I con not set as decoding from JPEG to any other format , why so ...

0) I like XnView MP and that's why I want help do this viewer better , so good how much it will turn out
1) ACDSee 2025 me not like , slow and big program with worst work with file format WEBP , AVIF , there this formats saving with lossy always
2) in version home , not pro , apl work worse
3) and ...

I sure what I right , you can compare files here https://www.mediafire.com/folder/gf051u ... ality+next , then you see what files 1x1 always coincide and if compare files 1x2 or 2x1 you can see what files not coincide

I'm afraid I don't understand what this request is about.
To my knowledge, dithering is used to prevent color banding and to improve (perceived) image quality during reduction of color depth .
If an image with a color depth greater than true color (= 24 bits = 8 bits per channel) is opened in ...

sure, but you should not keep this secret here, you need to tell ACDSee devs that they made huge mistake in modern versions.
Once they fix it you'll get all the glory, all other image viewers will kneel, maybe even the libjpeg devs will thank you too.


I'm sorry , but you still use coders and ...

Then explaine this https://www.mediafire.com/file/iidfvc7r ... s.avi/file this is subtraction result XnView MP of result ACDSee Pro 5.0

I'm understand what you do... you open original file and file recived from XnView MP , if yes , so clear why you so sayd
But this not means what so better

Why? You realy think what if images in ACDSee Pro 5.0 with ide_acdstd.apl version 5.0 look better , so me need to complain on this ? You sure?

I'm sorry , but I think what you all not understanding and not want understand what I write (
You can understanding differ between zooming and dithering ?
As I understand , you still think what I sayding about zoom process , this but your error , I'm sayding about quality encoding , and because JPEG ...
