Strange algorithm for drawing bold text #232

Open x-qq opened 4 years ago

x-qq commented 4 years ago

Currently, text that uses FONT_BOLD is drawn 1) using bold.ttf 2) which is drawn twice with a 1 pixel offset (on top of already drawn text).

I guess this is made to achieve even more boldness?

I think it would be better to simply use an appropriate font and not have to do this.

Appropriate bitmap fonts, free to use - do not get blurred by SFML.

Tried disabling the double-drawing code and using LiberationSans-Bold.ttf in place of bold.ttf.

Results:

libsans

This seems reasonably good?

According to https://en.wikipedia.org/wiki/Liberation_fonts it is available for use under a permissive license.

Original double-drawn bold.ttf for comparison:
