Description of the new feature / enhancement

• An option to trim the vertical white / Black vertical space in a comic chapter.
• Another option to leave ____ % vertical white / blank space in a comic when trimmed, bascially a limiter to not trim vertical white / black space below that.
• • _____ %, depends on the system's vertical pixel count.
• • For example, in a 1920 * 1080 px display. 20% trim limiter means, trim vertical white/black space > 216px.

Scenario when this would be used?

To trim down the large blank space in comics. Webtoons especially have large vertical white/black spaces in images.

Supporting information

Usage is very niche, but also kinda hard to implement because of many things.

• high chances of hitting a false positive, its very hard to decide if the white space is actually just blank or part of panel.
• high computation, loading will take more time, high cpu time, high ram usage.
• and if you want to add a custom field for deciding "%" of white space to leave, then on every change whole chapter will have to be re-rendered, so same cpu time as initial loading.

All that aside, I will only be able to work on it once gallery mode and #245 are done.

In my opinion, its better to have an external tool do this rather than Yomikiru, on all images in a folder at one.
If Yomikiru is doing this, that mean it will be done each time you open a chapter. There might be some tools for it already.

I couldn't find any app to do this. The apps I found are all designed to trim the white space around manga. Will comment here if I found any.

• This android app does this, but has no limiter option.
• It does the cropping thing (Vertical space + Horizontal space+ Image Strech/fitted into the empty horizontal space) in a second without loading. Maybe because its an android app and I used it on my mobile, I don't know. But its not perfect.
• Please check. This feature is titled 'crop borders' (or icon beside the settings icon when a comic is opened.)

This feature that I have requested, only needs to crop the vertical white/black space and not the horizontal white/black space.
