"backshift" -> do something to negate the translation, for example compute the bbox of the two and align the center of one to the other. Or maybe better the midpoint of the top of the bbox of one to the other. Taking the top-left corner might be an idea, but it makes it hard to realign by a subpixel amount.
And mind you: we need _tests_ not just the images, I want to investigate if making the images in a different format helps (with/withou aa, messing with resolution, ... whatever the case might be) L On Tue, Jul 30, 2024 at 11:47 AM Luca Fascione <l.fasci...@gmail.com> wrote: > Yes we do need a few tests set aside for this.
