Notes on OSD Font Creation

29.8.1

Note 1 on Font Creation (Font Width)

In OSD display, vertical and diagonal lines in fonts that are one dot wide may appear to be narrow
due to a shift of 0.5H. Display fonts should be created with liberal thicknesses.
29.8.2

Note 2 on Font Creation (Borders)

Borders extend beyond the character display frame in the X-direction, but no borders extend
beyond the display frame in the Y-direction. Moreover, when borders are to the right or left of
blank characters (H'000), borders extend beyond the display frame, but for the first and the 32nd
characters in a displayed row (16th character when the character size is enlarged to double height
× double width), no borders extend beyond the display frame.
Examples of borders which extend beyond the display frame appear in figures 29.16 through
figure 29.18.
