1. Yes, it doesn't follow the same aspect ratio. You'll have to change it. Just scale to the 270x192 resolution.
Yes, that's what I've been doing. Takes a bit more time having to unlock the AR and type the different res, especially when testing what works best when rescaling... oh well, no idea why they would've chosen to do this. Probably something left-over from the older games.
2. I have already recommended GIMP in this forum, but I use Photoshop. I used to work with computer graphics and I still have an older version of it. For the mod, I used the bicubic sharper (photoshop has 3 bicubic interpolation methods). Nearest neighbor tends to present sharp results, but usually causes jagged edges. I would have to open GIMP (it's installed on another computer) to remember the methods available. Anyway, if you can't find a decent method, send me the files and I'll try to scale them in Photoshop for you. Yet, for the smaller size, because of the different aspect ratio, you'll necessarily have some loss. You can try to sharpen it after scaling, too. Just place some TOAW map on a lower layer and work on it with filters and manually, if necessary. There's only three tiles for dug-in positions.
Yes, I would guess PS probably has more options, and higher quality, given it's a paid product and used by the pros.
In Gimp 2.10 there's:
- Cubic (Is this is the same as bicubic?)
Apparently, the last two replaced the old Sinc/Lanczos I remember from older versions. Not sure if these new ones are better.
LoHalo is supposed to be better for downscaling more than half, but I think Cubic seems to be better.
Linear is maybe "nearest neighbor"?
I think the game does some scaling as well, so probably it doesn't matter much when zoomed out anyway.
I've used Gimp for many years but not regularly, so I only know the basics, what I've needed for small modding projects. I like it though, the new 2.10 is really good, and with a dark theme so it looks like PS
