RFC: Improve annotation magnitude clarity #208

Closed qpwo closed 2 weeks ago

qpwo commented 1 month ago

When looking at currents in an annotated circuit, 843.76f and 843.76n look rather similar. So do 843.76f and 8.4376f. Sometimes I make mistakes because of this. I wonder if there's some easy improvement to make? A few ideas, best ideas first:

  1. make bigger numbers a bigger font
  2. add option to use fixed precision. If you set it to e-11 then the number would always render like XXX.XXn. I guess it would be separate options for currents and voltages. Or maybe only an option for currents.
  3. make the f,n,u, etc different colors
  4. add an option for minimum current to show in annotation

I think any one of these would be sufficient and a great improvement

You can make texts bigger by adding attribute text_size_n=s, where n is an integer representing the text item in the symbol: 0= first text item, 1= second text item and so on, s is a double representing the desired text size. In a lab_pin.sym label adding text_size_1=0.5 will make the annotated voltage value bigger than default (0.2)

This is an example where both label and annotated voltage are set to bigger size. See the text_size_* = 0.7 attributes: 1
