I am working on making some books for Amazon KDP using Page-o-Mat, so that’s driving feature development right now.
I decided to create cover art using vector drawings, so I added the ability to add a list of drawing objects to a page. I currently support rectangles, ellipses, lines, text, and QR codes. Each object has keys to set stroke, fill, alpha, and other parameters.
A cover in KDP needs to be big enough to support the trim, bleed, and spine, so it ends up that page size is an arbitrary number. I had only supported standard sizes, like A5, Letter, etc. Now Page-o-Mat supports custom sizes and orientation.
I uploaded some books to KDP today. When they are approved, I’ll announce them here.
