I created some artboards in Affinity Designer, and gave each artboard a specific height and width. I also want to export each artboard, so I changed to the Export Persona, but to my surprise, the slice has a different size than what I expected (from the screenshots in this question, the Export Persona slice added one pixel to the width). How can I make sure that the Export Persona is using the same size as in the Designer Persona?

For only one artboard, I would just change the size manually, but I have 64 artboards!

I am using Affinity Designer 1.8.1 on macOS Catalina 10.15.3.

It seems that my artboards were not aligned pixel perfect, and the slices need to guess the width and height because of it, thus 1 pixel error occured.

I posted my question on the Affinity Forum, and I got help from someone there, who pointet it out for me.

I ended up creating a new document, forcing pixel alignment from the start, and now the slices are correct.
