Wow, Mark. Impressive. Many thanks.
Easy Windows "hack" for creating a .PNG from a .PDF: use the Windows "Snipping Tool" or "Snip & Sketch" tool to capture the screen shot of the .PDF. The image can then be saved or copied and pasted.
Accessible via your keyboard in Windows: Windows + Shift + S to bring it up. Better yet, find it in Windows and save it to your taskbar. Snipping Tool can be found at: C:\Windows\System32 .
