Yeah, come to think of it, I now remember that I already used that "move" function before, when I created my Alde family of fonts -- so that's the easy part!
I haven't the slightest clue how to get my two fonts the same size in the first place, though. I'm assuming that it's a matter of "getting all the lines to match up" (so to speak), that is, getting my x-height, cap-height, etc. to all be the same, but the easiest way that I can think of to do that is to just start practically from scratch -- open up my Thoreau font, "save as" as a new Falsum font (the one of my own handwriting, which I want to match up to my Thoreau font), and then copy/paste each glyph, one at a time, from Falsum into the slots that were my Thoreau font.
If that makes any sense -- but all I can think is that surely there must be an easier way? Like, in the Font Properties dialog there's all those tabs, with various buttons to "calculate" different things. I always do run those "calculate" things, but I don't entirely know what they all mean.
If I wanted to make my Falsum font match up with my Thoreau font, then I presume I could just simply copy/paste certain numbers from within the Font Properties dialog from one font to the other, and that would do the trick?
But which numbers? There's a LOT of different numbers, lots of different "calculate" buttons.
Or maybe I'm off in the wrong direction, and there's another, better way to do this???
