Is there a utility program available that enables one to create custom screens for the STM32L053 Discover Board? I've looked at a couple of demo programs for the E-Paper display and see that the graphics elements are contained within data structures. Is there some kind of a utility program that allows one to create the images visually or import them from a utility program used to create them visually so that they can be added to the various data structures used to build the screens?

Looks like STM Application note AN4500 How to display size-optimized pictures on a 4-grey level E-Paper

from STM32 embedded memory does a good job of answering my questions.

That appnote refers to XNView (according to wikipedia, It is licensed as freeware for private, educational and non-profit uses. For other uses, it is licensed as commercial software.) as the conversion utility. My impression is that the result is monochromatic, but did not dig deeper. Please report  your findings.
