Feature request: .sai2 preview support in XnView MP

[natsu]

Hi,

First of all, thank you for creating XnView — it’s an excellent image viewer, and I use it regularly.

I draw with PaintTool SAI 2 and often keep many .sai2 files. It would be very helpful if XnView MP could show previews/thumbnails for .sai2 files, so I can browse them the same way I browse PNG/JPEG.

For reference, I built a research plugin and got .sai2 preview working on XnView Classic (Susie plugin). The same approach does not currently work with XnView MP:

.sai2 does not store a plain embedded PNG/BMP. The preview comes from canvas chunks (thum / intg) that need decoding. My repo includes notes and sample files if that helps.

I’d really appreciate it if XnView MP could support .sai2 preview in a future update. Thank you again for your work on XnView.

Best regards,
Natsu
