Font kerning #73
Description
kerning - the process of adjusting the spacing between characters in a proportional font, usually to achieve a visually pleasing result.
LVGL and lv_font_conv supports it, and built-in fonts seem to use it.
With ESPHome's font renderer, lack of kerning is noticeable:
See the space between í and c is bigger than the space between i and o simply because the accent of í pushes it to the right.
To reproduce:
- file: 'fonts/RobotoCondensed-Regular.ttf'
id: roboto_condensed_20
size: 20
bpp: 4
glyphs: [
0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,á,Á,é,É,í,Í,ó,Ó,ö,Ö,ő,Ő,ú,Ú,ü,Ü,ű,Ű,\,/,
