Drop the four corners onto your photographed chart's corners, and the app straightens the photo into a flat, markable chart. It turns a wonky snapshot from a book, magazine or screen into a page you can stitch from.

This step appears when you start a project from a photo, the camera or the gallery, rather than a PDF.

Placing the Corners

Corner handles (x4)

[Screenshot: a photographed chart with the four corner handles placed on the grid corners]

Drag each one onto a corner of the printed grid. They cannot leave the photo.
Edge handles (x4)
Fine-tune each side of the outline.
Magnifier
Appears when you tap a handle. Tap an arrow to nudge 1 pixel, double-tap for 5. The outer arrows jump you to the other corners.

Chips and Buttons

Rotate chip
Turns the photo 90 degrees. Do this FIRST: rotating re-detects the corners and discards your adjustments.
Split into pages chip
Cut one big photo into several pages (new projects and added photos only). Full guide.
Next
Asks Whole Page (straighten the page, then frame the grid in a second pass) or Chart Only (crop straight to your corners).
X (close)
On a new project, abandons it. On a queued photo, cancels just that photo.

Did you know?

  • Previously impossible: stitchers asked for an easier way to load photos and self-scanned charts. This step is the answer, making a chart that only exists on paper stitchable in the app.
  • Warped page? Choose Whole Page at Next. The second pass lets you straighten the auto-detected grid before it becomes your chart.
  • Adding several photos? The title counts them through, for example "Adjust Corners (2/4)".
  • A photo that cannot be read shows a message, and Next politely refuses. There is no Back button on this step, and that is by design.
