One axis only
A strip is a split along one direction. That sounds like a special case of a grid, and on the board it is — one column of four rows is four stacked strips — but the questions people bring to it are different. With a long chat screenshot or a scanned receipt the question is how tall each page should be and whether text survives the cut; with a panorama it is how many columns and where the seams fall. This route opens the board with a Strips panel that asks exactly those questions.
By count, the spare pixels are shared out one at a time so the strips differ by at most one pixel and add up exactly to the picture. By length, every strip is the height you set and the last one takes whatever is left, so a 1080-pixel-wide screenshot 7000 pixels tall cut at 1920 gives three full pages and a 1240-pixel remainder rather than a squashed last page.
A worked example
1080 × 7000 → 4 files · columns 1080 = 1080 px · rows 1920 + 1920 + 1920 + 1420 = 7180 px
| File | Cell | From x, y | Pixels |
|---|---|---|---|
| screenshot-r1c1.png | row 1 · col 1 | 0, 0 | 1080 × 1920 |
| screenshot-r2c1.png | row 2 · col 1 | 0, 1860 | 1080 × 1920 |
| screenshot-r3c1.png | row 3 · col 1 | 0, 3720 | 1080 × 1920 |
| screenshot-r4c1.png | row 4 · col 1 | 0, 5580 | 1080 × 1420 |
Overlap is for readers
A cut through a line of text leaves the top half on one page and the bottom half on the next, and nobody can read either. An overlap repeats a band of pixels across each join, so the line appears whole on one page or the other. Forty to eighty pixels is enough for most screen text at phone resolution. For a panorama posted as columns the opposite is usually wanted — no overlap — so the columns line up edge to edge when swiped.
The 9:16 and 4:5 chips are starting lengths, labelled as commonly used because they match the shapes most phone screens and feeds display, not because any platform requires them. They scale with the picture: on a picture 1440 pixels wide, the 9:16 page is 2560 pixels tall.
A strip holds the pixels of the picture and nothing more. Cutting a small screenshot into many pages does not make any page sharper; it only makes each one shorter.
How to do it here
- Open the picture. Drop a long screenshot, a scan or a panorama on the board.
- Choose the direction. Under Strips, pick Stacked or Side by side.
- Count or length. Set a number of strips, or a strip height — the 9:16 and 4:5 chips fit pages to the picture's width.
- Add an overlap and cut. Set the overlap in pixels (or press [ and ]), then cut.
