void tfont (hwid) FNTPLT.C Level 13
int hwid The width (in pixels in the 8192 ´ 6266 GraphiC pixel space) of the line. Using very thick lines slows down plotting. A value of 5 or less is recommended, and 10 is the maximum allowed.
tfont() sets a parameter that specifies the width of lines used to make thick fonts. Thickening will be toggled when the escape symbol # has been inserted into the strings. tfont() should not be used with filled fonts.
