Worked example
A 600 × 400 mm poster, 210 × 210 mm paper, 5 mm margins and 10 mm overlap gives 4 columns × 3 rows: 12 PNG pages.
Method
Subtract margins for each printable page. Step by printable size minus overlap, preserving image proportions inside the target poster. Edge tiles cover the remaining area.
Limits
Static JPEG/PNG/WebP up to 20 MiB and 40 million source pixels. At most 100 pages, 40 million pixels per page and 150 million combined. PNG output, not PDF or ZIP. Software may ignore resolution metadata; confirm paper size, disable fitting and measure the separate ruler first.
