Choose a template or import an existing layout, then drag, resize, and edit text or object regions. The editor exports centered yxyx boxes for MOSS-Image; generated placement and lettering can still vary.

From regions to a valid layout prompt

Boxes use [top, left, bottom, right] order and coordinates measured from the canvas center. Keep regions broad and separate, copy the generated JSON, then test it in Studio before relying on the design.

Need field definitions, canvas ranges, and error examples? The MOSS-Image JSON Layout Guide remains the reference page.
