I have made a sketch in Visio.
I plan to save it to
I have the option of saving as PDF/A-1 (a or b not specified).
Would I want to make a habit of saving these images as PDF/A,
or is this completely superfluous for the purpose.
A reasonable algorithm would be:
Review the generated PDF file. Are all needed features present, is the PDF file viewed and imported correctly?
If yes, then the generated PDF file is very likely the better choice, more robust and better suited to be used in later years. Done.
Else, goto 4.
Export via PDF. Done.
