Transposes all characters in a font.


int transpose_font(FONT *f, int drange)
This function transposes all characters in a font, effectively remapping the font. Example:
      FONT *myfont;
      FONT *capitals;
      /* Create a font of only capital letters */
      capitals = extract_font_range(myfont, 'A', 'Z');

/* Now transpose the characters in the font so that they will be used */ /* for the lower case letters a-z */ transpose_font(capitals, 'a'-'A'); textout_ex(screen, capitals, "allcaps", 100, 100, makecol(255,255,255), 0);
Returns 0 on success, -1 on failure.
