Looks like you’re right. I checked the debug output of the fit_font_into_metrics proc:
In Tk 8.4 with Monaco, I get 6 4 7 7 4 9 8 5 10 9 7 11 10 6 13 … And in Tk 8.6: 6 4 9 7 5 10 8 5 11 9 6 12 10 7 14 … I wonder if this is a rounding error? > On Feb 12, 2017, at 9:20 AM, Miller Puckette <m...@ucsd.edu> wrote: > > About that padding - the Tcl code sends Pd the font metrics on startup, and > Pd follows them in setting the dimensions of boxes.
