Here is an example result:

High resolution sample image

Epitome for sample image

The epitome itself may not be very interesting, however, it can be used to reconstruct details of a degraded image.

Original low resolution image

However, there were only four templates available for the layout and style of the PDF. During my internship at Solidworks Labs, I created Presentation Studio Theme Editor, which allows users to create their own templates. Some of its features are:

  • What you see is what you get
  • Drag and resize elements with snapping
  • Z-ordering
  • Context pop-up bars
  • Undo and redo
  • Drag and drop images and text
