Re: [PATCH] Zoom to fit on empty canvas
Hi John, JP,
I will take a look at how this would work with GerbView, hopefully later
There is no worksheet item in GerbView, so we might want a more abstract
idea of what the "default view" should be.
For the units question, for sure this needs to be resolved, I don't have
suggestions yet until I look at the code some more. But, I would think it
makes sense for GAL to work on one units system across all applications,
and code in common to use that units system also, and then it is up to
applications to scale things when they insert them into GAL views.
