Export preview - add JPEG-LI

[meteorquake]

I've removed the old JPEG from the save as types, to leave only JPEG-LI.

* It would be handy to have a JPEG-LI preview option under File - Export...

Given the great usefulness of this and the fact that it is basically the same as the JPEG hopefully this would be a relatively trivial thing.

IMHO in Export will be better change turbo-jpeg on jpegli.

however, I would go further and remove dead/dying/unnecessary_for_export formats:
bmp
jpeg-2000
jpeg-xl
jpeg-xr
pcx
tga

leaving there only few formats (eg Photoshop has only gif,png,jpg in Export dialog):
avif
jpeg
png
tiff - maybe remove it as well
webp


Want to save into other format? - use "Save as..."

Jpeg XL is not unnecessary format
It is future format, which replace jpg, png, gif, webp, tiff on very wide fields industrially. Google may try to stop jxl in browsers but even here it will appearance.
You will see...

Yes, I wouldn't remove those lossy-enabled formats. In everyday usage they have a small edge in terms of result although they are slower and for many purposes the speed of some of them (e.g. JPEG2000) may be a real block to their usage - but for some it is not, and non-everyday usages may prefer them.
I don't have a problem with less-used formats being there, or ones that are part of historical interest for those who love format history, but perhaps at some point they could be put in a lesser priority position.

Thanks to your detailed description I can reproduce the problem.

The export dialog is very important for standard picture formats for internet websites and testing new formats and their settings.

So the following formats are very important for me.

- JPEGLI encoder
- AVIF
- HEIC/HEIF
- WEBP
- PNG
- GIF

---

Unimportant formats for export dialog:
- BMP
- TIFF
- PCX
- TGA

This problem is supposed to be fixed in XnView MP 1.8.1. Please check and confirm the bug fix here.

I get a strange colour effect for the preview when choosing JPEG-LI (I tried different settings but that didn't make any difference), which doesn't happen when that is not ticked, however the actual export is okay.
Screenshot of export preview problem and a sample file causing it are attached.
