Calamus SL vs Laidout

Calamus SL has no write-up on Specifiction yet; its figures are above.

Laidout is free Linux desktop publishing software for arranging pages into folded print layouts, including book signatures, accordion folds and polyhedron nets. It also supports single pages and can help arrange posters for printers limited to small sheets. Its graphics objects include paths, ellipses, rounded rectangles, gradients, point sets, color meshes, warped images and captions. Laidout imports SVG, images, Scribus files and OFF polyhedra; PDF pages can be imported as rendered images, though PDF page import for reimposition is under development. Export options include PDF, SVG, Scribus, images, HTML galleries, Podofoimpose plan files, Page Atlas images and PostScript. Command-line use supports batch import, reimposition and export without opening a window. Laidout is released under GPL 3.0. The homepage identifies version 0.097 and says the stable release is old, suggesting a development snapshot or compiling from source where possible. Proper color management has not been a development priority; the FAQ suggests exporting to Scribus for that work.
