I want to make book covers using Indesign's Data Merge.
The indd is a spread where page 1 is the flap from the back cover, page 2 is the back cover, page 3 is the spine, page 4 is the front cover, page 5 is the flap from the front cover.
Page 3, the spine, should vary it's width from a value set in a CSV used for data merging all variable text and images. It should then export to PDF with the correct spine width.
Could this be done using Basil.js ?
I haven't tried Basil.js before.
