11-56 Soft Font Creation EN
Orientation (UB)
Orientation byte specifies the orientation of the character. The
orientation of the character must match the orientation of the font.
If the orientation is not supported or is different from the orientation
specified in the font header, the character is discarded.
Left Offset (SI)
Left offset specifies the distance in dots from the reference point to
the left side of the character pattern on the physical page coordinate
system (this value is orientation dependent). The left and top offsets
locate the character reference point about the cursor position (see
Figure 11-6 and Figure 11-7).
PCL 5 printers support kerning (both negative left and right side
bearings) of both fixed-pitch and proportionally-spaced fonts. Note
that large offsets could place the character off the printable area of
the page causing the character to be clipped.
The legal range for the left offset is –16384 to 16384 dots.
Top Offset (SI)
Top offset specifies the distance in dots from the reference point to
the top of the character pattern on the physical coordinate system
(this value is orientation dependent.) The left and top offsets locate
the character reference point about the cursor position (see Figure
11-6 and Figure 11-7). The legal range for the top offset is –16384
to 16384 dots.
