I wanted old style vector fonts in a program and realized I had to work them up myself. Here's a demo program that goes along with the scribble font editor I posted earlier.

Thanks. Sometime someday the text might rotate but I really don't need that for what I wanted these for. Looks like careful placement of the line segments when initially draw might speed it up (not sure however).

Here's what Bplus Font looks like:
I had to make special arc and line drawing subs which draw thickness by drawing thousands of tiny circles along a line or arc.

Circles following the lines was where I figured I'd go if I wanted to make thicker lines. I just fiddled with slapping them at the coordinate points for the line segments so far (because it's lazy-easy).

I took the plunge and used the circles technique to plot the points on the lines. It isn't perfect yet because I'm using the default circle drawing but it certainly works.

I updated the main font drawing subs to make use of draw, which simplifies rotating the text. I haven't gone full draw commands and may not as the scribble font code is small and the conversion between the two schemes makes for more dynamic scaling options. The scribble font editor will be getting some updates but not likely to see them for a few days.
