Layouts
A layout is a paged document: a stack of spreads with one page size, optional facing pages, bleed and margins. Images are placed on spreads exactly as they will print — use it for catalogues, portfolios and photo books.
Page setup
Choose the page size, orientation, facing pages, bleed and margins when you create the layout; all of them can be changed later from the settings dialog in the editor. Bleed and margin guides are drawn on every page.
Adding images
Open the library sidebar to browse and filter your files. Drag tiles onto a page (or the pasteboard beside it), or double-click a tile to drop it at the centre of the view. Every image belongs to the spread it sits on.
Boards
Don't need pages? A board is the free-form sibling of a layout: the same editor on an infinite canvas.
