Clipping large image into smaller sections

[Daisyyy]

Hello, 

i a trying to split up a large image into three smaller ones with a bit of an overlap on each page. My image is about 20x18. I would like to print it on 3 pages but be able to overlap the pages after I print them. How is this possible? In Inkscape it is clipping. Not sure how to do this in affinity.

Convert it to PDF and choose "Poster" when opened in Acrobat Pro.

If you use the ‘Place’ command in Affinity Photo, the canvas will act as a window onto the placed image where only what you see on the canvas will be included when you export to any image file format. So, if you create a new document at the desired tile size and click to place the original image on it at full size, you can simply adjust its position to give you each of the three overlapping tiles.
