Default Feature Request: New image scaling option

I wrote a script that detects scene cuts in video and put JPEG thumbnails on new items representing the cuts.

But the thumbnails look pretty crazy in practice because of the default image scaling strategy.

I think there should be an option to "scale images based on item height only" (it should center & crop the image too after scaling)

First: That script is a very clever idea. Very nice!

And yes, this preview looks a bit weird. But those thumbnails only get shrink because the item width is to small. If you zoom in, they all should fit in but also get repeated horizontally.

Do you mean you want the image stay at max height and that it should be cropped by the item boundaries? Because this would be the only option I could imagine. But this would crop it really far if the item is very small (short). And the chances are high that you then can't recognize anything if you zoom out to far. (Though you also can't see whats on the image wwith the actual behavior.)

Anyway. The option would be a good idea. And also the option to stop the repeating preview. (Or is this already possible?)

My scipt is just a wrapper around a free tool called scenedetect. My script calls that to find cuts & generate the thumbnails. So that needs to be installed first.

I couldn't find an option to change scaling strategy.

Yes I mean option to always use full item height, then centre and crop the image if not enough space.

Usually what you want to see most of is in centre anyway, so cropping a bit off won't matter - shrinking it makes it even less recognisable to me.

In the meantime, this thread might help, especially Justin's answer.

That seems more to do with what happens in the video window than thumbnails on items.

Correct, plus only working with images that have transparency (using the image overlay preset)..plus it's been fixed with the latest update.

Its still a great idea.

And I have to agree: It would be better to let the thumbnails untouched in their size. I remember, I also stumbled over this scaling problem while once creating a picture show. It looks ugly, makes the images unrecognizable and destroys the overall design of the arrange view.

So please allow an option or change it completely. Also the repeating isn't very helpful as it implies it would be a sequence or a video file instead of an image. Just the thumbnail at the beginning of the item should be okay.

Many thanks
ELi
