Images2Pen

Images2Pen makes a bunch of images into a Penultimate(.pen) document with a bunch of pages, so you can draw on them with your Penultimate application.

Background

I LOVE Penultimate. I've been using it since the first version was released with my first-generation iPad, and 3M Smart Pen. It was just awesome, more after adding image is supported.

However, what I really wanted to do is get rid of heavy books or lecture notes in my backpack. There are many PDF/PPT annotation app in the App Store, but none of them satisfied me as much as Penultimate.

So I started to think, what if I can make Penultimate document on my Mac, with images rendered from PDF or PPT, put it on my iPad, and draw something on the images.
