console.log(o_binary_string.s_binary_text)

change threshhold

the threshold controls how much of the font will be visible, foreach FontFace there is a best threshhold value

o_binary_string.n_threshhold = 0.0
console.log(o_binary_string.s_binary_text)

logs the following, because threshhold is set to 0.0

                          xx
  xx                xx    xx
 xxxx               xx

xx  xxxxxxxx  xx    xx      
              xx            
            xxx

change font face

a very good font face is visitor1

var s_font_url = "https://fonts.cdnfonts.com/s/7338/visitor1.woff"
await o_binary_string.f_load_font(s_font_url)
console.log(o_binary_string.s_binary_text)

Deno

because of the not supported document.createElement("canvas") and the not supported new FontFace(...) on denojs, O_binary_string works only with a simple ‘arial’ font. nonetheless it works!

new O_binary_string("O_binary_string", 15)
