How it works
Slicing by height
Each slide is as tall as the image and as wide as the shape you pick makes it, so a 4:5 slide of a 1000 px tall image is 800 px wide. The slide count is the image width divided by that, rounded up, so nothing is cropped.
slides = ceil(image width ÷ (height × ratio))
The leftover space
When the width does not divide evenly, the first and last slides get a fill: a blurred copy of the edge of the photo, or a colour you choose. The image sits centred across the strip.
