Spread splitter not keeping aspect ratio

[Zaphain]

When using split and rotate, regardless whether upscaling is set to keep the aspect ratio, the resulting three images will all be stretched to the full resolution. I'm unsure if this is a bug in behavior or whether I should be asking for an added option to have the aspect ratio preserved here and the images instead be centered.

Do you have an input example ?

On closer look, it seems the rotated image is fine, it's just the split ones. Those are definitely stretched. The correct aspect ones were just done in imagemagick to show what I think it should be. (There's a typo in one of the image descriptions, but nevermind that, you can tell what I mean)

Also, I think if you wanted to keep more of the feeling of the pages being connected, you could left align image b, and right align image c. That might be best instead of centered.

I could confirm that issue happen to me too.
I run KCC in webtoon mode, option Strech/upscale had been auto-checked, but the ratio of the result are not keep

I'm unable to reproduce your problem.
With those settings:

I get the following, where orig.jpg is the original image

Okay, I see where the issue is, this doesn't happen when epub is chosen as the output, it's only affecting the KFX output. https://imgur.com/a/uqDTyo7

OK, it must be here in the code.
KFX mode is stretching for split images

kcc/kindlecomicconverter/image.py

Lines 312 to 313 in 88ffcef

	if self.opt.stretch or (self.opt.kfx and ('-KCC-B' in self.targetPath or '-KCC-C' in self.targetPath)):
	self.image = self.image.resize(self.size, method)

I've tested with Calibre and KFX Conversion Output Plugin without the stretch.
It works. I'll commit this and make a new release.
I must admit I've never used the KFX output before, only MOBI files.

Could you please check this issues with these setting. The ratio is not keep
