NAME

system_defaultfont - Set / Replace the current default font

SYNOPSIS

boolres, height, baseline,
system_defaultfont( fontres, fontsz, fonth, fallback )

DESCRIPTION

For text rendering functions, some kind of font is needed. The default font is set either by using this function, or indirectly through the first render_text call with an explicit font ( arg. fontres is a string reference to a valid file in the SYS_FONT_RESOURCE namespace, fontsz is the size argument as used in render_text and fonth specifies anti-aliasing strength (0: disabled, 1: light, ...) It is also possible to specify an additional fallback font that will cover missing glyphs not found in fontres . The downside is that the glyphs might not visually blend with the primary ones in a visually appealing way, but may still be better than invisible characters.

NOTES

1

This is also implicitly updated in LWA arcan builds if it receives a FONTHINT event from the display server connection, and there is no event-trigger to detect if that occurs.

EXAMPLE

function system_defaultfont0()


      system_defaultfont("default.ttf", 12, 0);
end
